What is Test Automation: Benefits, Strategy and Best Practices

OVERVIEW

Automation testing utilizes software tools and scripts to automate the execution of tests in software development and quality assurance processes. It involves writing and running automated test scripts, with the primary objective of reducing human intervention and enabling the repetitive execution of tests. This not only saves time but also enhances overall test coverage.

Automation testing proves cost-effective in the long run, where manual testing struggles with repetitive tasks, such as regression testing, causing increased pressure on manual testers as software expands. Despite the initial effort, automation testing is more efficient, reducing errors, speeding up test completion, cutting costs, and improving software quality.

Testers use frameworks like Selenium, Playwright, Appium, etc., to automate test cases and accelerate execution, which is especially beneficial for repetitive tests like integration and regression testing. Faster tests yield quicker results, providing teams with frequent feedback for issue detection and functionality improvement.

In this tutorial, we will look into each aspect of test automation, starting from knowing what it is, its benefits, types of automation testing, and more.

Let’s get started.

What is Automation Testing?

Automation testing is a software validation method that ensures software functionality aligns with end-user requirements before release, allowing organizations to conduct specific tests without human intervention. Automation testing proves highly effective for handling large or repetitive test cases.

Organizations aim to save time, reduce costs, and enhance overall software quality by automating repetitive and time-consuming manual testing procedures. Automation testing serves the purpose of cross-checking if a software application performs as expected.

This involves using scripted sequences executed by testing tools, with outcomes reported and results compared to previous test runs. The advantage lies in the reusability of automated test scripts, promoting efficiency and consistency.

Benefits of Automation Testing

In software testing, the significance of test automation lies in its ability to speed the testing process, making it more efficient and less open to human errors. With the capability to execute tests quickly and frequently without human intervention, automation allows for the early detection of issues and ensures a faster testing cycle.

Which Tests Should Be Automated?

This section focuses on what test cases to automate and what to not. Let’s explore it in two parts: What is automated testing (automatable) and automated testing (non-automatable)? Even though you can automate tests such as smoke, sanity, and regression tests, tests requiring human expertise might need manual intervention. Here is a table demonstrating the same.

What are the Types of Automation Testing?

Automation testing comes in various forms, each serving specific purposes in software development. Common types include Unit Testing, which examines individual components, and Functional Testing, which assesses overall system functionality. Collectively, these methods enhance efficiency and reliability in the software testing process. Let’s check all the different types of automation testing below.

Functional Testing

Functional testing checks if the features of an application meet the software requirements, ensuring they deliver consistent results that align with what users expect for the best performance and experience. It involves testing by providing inputs and checking if the outcomes match what users expect.

• Unit testing

This type of testing is done by developers while writing code for an application. The main goal of unit testing is to check if each part or unit of the code works correctly. It ensures you get the expected output when you give a particular input to an element of the code. Unit testing is like building the foundation for more complex features in the application.

For instance, an e-commerce website that allows customers to order personalized T-shirts. The website has various functionalities like selecting a color or the T-shirt, adding custom text, and choosing a size; during unit testing, developers test each of these functionalities individually to ensure that each function works as expected.

• Integration testing

When different developers build modules or components separately, quality engineers must check if these parts work well together. This is where integration testing becomes crucial. Integration testing ensures a system’s various modules and components function correctly when combined.

In modern software setups, microservices often interact with each other. Integration testing becomes even more critical to guarantee that these microservices communicate properly and operate as intended.

For instance, consider a banking app where users can set up a savings account, and there’s a feature to transfer money from their main account to the savings account. Since these are separate modules, testers would perform integration testing to ensure the transaction process between the two functions is smooth and accurate. This ensures that all parts of the banking app work seamlessly together.

• System testing

In this testing phase, the software undergoes comprehensive testing to confirm that all business and functional requirements are fulfilled. This testing is often called end-to-end testing and occurs just before user acceptance testing.

The system testing environment must closely mirror the production environment for accurate validation. Additionally, it follows the white box testing method, where testers have no involvement in the development of the system.

For example, consider a fitness app with features like setting and tracking monthly fitness goals, consolidating fitness metrics, creating personalized exercise sessions, and integrating with smartwatches. Each function is evaluated individually and collectively in system testing to ensure smooth integration.

• Regression testing

Whenever software introduces a change or new feature, there’s a risk of disrupting existing functionalities. To ensure the stability and continued performance of the software, regression testing is conducted each time alterations are made. Due to the labor-intensive nature of regression testing, it’s often automated for efficiency.

For instance, let’s take a widely used software application. The Chrome browser has introduced a new feature that improves bookmark management, where users can now organize bookmarks into folders and subfolders with nested structures. This new feature provides a more organized and user-friendly bookmarking experience.

Now, the development teams need to perform regression testing to ensure that this new bookmark management feature doesn’t affect the core functionalities of the web browser.

• Smoke testing

When a new software build is completed, it undergoes smoke testing by Quality Assurance (QA) to ensure that only the most critical and essential functionalities produce the intended results. This phase, often called smoke testing, serves as an early-stage acceptance test, adding a verification layer to decide whether the new build can progress to the next stage or requires rework.

For instance, Imagine a team is working on a weather app, and they have just completed a new version. Before extensive testing, they perform smoke testing to check the core functionality that provides current temperature information quickly.

The QA team performs a quick check to ensure that, when a user opens the app, it correctly shows the current temperature for their location. So, if the smoke test passes, it indicates that the fundamental aspect of the weather app — offering the current temperature — is working as expected. If it fails, the team knows an issue needs immediate attention before further testing.

• Sanity testing

Like regression testing, sanity testing is done for a new software version with small bug fixes or added code. If the new build doesn’t pass sanity testing, it won’t proceed to more detailed testing. While regression testing looks at the entire system after changes, sanity testing focuses on specific areas affected by new code or bug fixes.

For instance, consider an e-commerce website where users cannot add a specific product to their cart even when it is in stock. After fixing this issue, sanity testing is carried out to ensure that the “add to cart” function works correctly.

Non-functional Testing

Non-functional testing evaluates a software application’s performance, usability, dependability, and other non-functional characteristics. Unlike functional testing, it focuses on aspects beyond specific features. This type of testing aims to ensure the software meets non-functional criteria, such as reliability and efficiency.

• Performance testing

Performance testing ensures a software application meets its performance goals, including response time and throughput. This type of testing reveals how various factors, such as network latency, database transaction processing, data rendering, and load balancing between servers, impact the performance of the software. Performance testing is typically conducted using tools like LoadRunner, JMeter, and Loader.

For instance, consider a popular e-commerce website set for a big sales event, expecting massive user traffic. Performance testing becomes crucial to ensure the website can handle the increased load without slowing down or crashing. Performance testing tool simulates many users accessing the website simultaneously, checking how well the site handles this increased demand. It assesses response times for actions like product searches, adding items to the cart, and completing the checkout process.

• Load testing

Load testing is a critical aspect of software testing that assesses the stability of an application under a specific load, typically equal to or less than the anticipated number of users. In practical terms, if a software application is designed to handle 250 users simultaneously with a target response time of three seconds, load testing is conducted by applying a load of up to 250 users or a number slightly below that. The primary objective is to confirm that the application maintains the desired response time of three seconds even when subjected to the specified user load.

For instance, imagine an online banking system expecting a maximum of 500 users accessing their accounts concurrently during peak hours. Load testing is executed by simulating this user load to validate that the system remains stable and responsive. The goal is to ensure that the online banking platform can efficiently handle up to 500 users without experiencing performance issues or delays, meeting the expected user experience criteria. This type of testing is crucial for identifying potential bottlenecks and optimizing the application’s performance under realistic usage scenarios.

• Stress testing

Stress testing is conducted to verify that a software program or system can withstand an unusually high load or demand. For instance, stress testing could involve subjecting a web application to many concurrent users attempting to log in simultaneously. This assesses the system’s ability to handle stress and high traffic volumes without compromising performance or functionality, ensuring a robust user experience even during peak usage.

For instance, consider online ticket booking platforms expecting massive traffic during an event or festival. Stress testing would simulate a scenario where a significantly more significant number of users than usual try to access the platform simultaneously to ensure that the system remains responsive and functional under such intense demand.

• Volume testing

Volume testing is used to verify that a software program or system can effectively handle a substantial volume of data. For instance, if a website is designed to accommodate traffic from 500 users, volume testing assesses whether the site can manage the specified volume without experiencing performance issues or data overload.

Let’s take an example of an online database management system used by large e-commerce platforms. Volume testing will ensure that the uploading and managing an extensive dataset and transaction between records is done effortlessly, without slowing down the performance of the database system even when handling large volumes of data.

• Usability testing

Usability testing ensures a software program or system is user-friendly and easy to navigate. For instance, in the context of an e-commerce website, usability testing could focus on determining whether users can quickly locate essential elements like the “Buy Now” button. This type of testing assesses the overall user experience, including navigation, instruction clarity, and interface intuitiveness.

For instance, consider that a mobile banking application is under usability testing, and testers evaluate how easy it is for users to perform everyday tasks such as transferring money or checking account balances. Testers check the clarity of interface and easy navigation and if the mobile application is user-friendly and satisfies its users. The goal of usability testing is to ensure that the users can clearly and effortlessly interact with the application with a positive user experience.

To execute usability testing, you must be aware of its various methods. Explore this guide on usability testing methods. This guide will provide you with different methods by which you can make your usability testing effective.

• Compatibility testing

Compatibility testing ensures a software program or system is compatible with other software, operating systems, or environments. For example, during compatibility testing, a tester checks that the software functions seamlessly and without issues when interacting with various software applications and operating systems.

For instance, Compatibility testing is performed to see if the software works well on different web browsers (Chrome, Firefox, Safari) and is compatible with various operating systems (Windows, macOS, Linux) and checking how the software integrates with other tools commonly used in project management, like communication platforms or document-sharing applications.

• Accountability testing

Accountability testing is conducted to verify if a system functions as intended. It ensures that a specific function delivers the expected outcome. If the system produces the desired results, it passes the test; otherwise, it fails.

For Instance, consider an online shopping website where users can add items to their shopping cart and proceed to checkout. Accountability testing for this system involves checking if the “Add to Cart” function works correctly. If a user adds a product to the cart, the system should accurately reflect, and the item should be visible in the user’s cart.

• Reliability testing

Reliability testing assumes a software system functions without errors within predefined parameters. The test involves running the system for a specific duration and under certain processes to assess its stability. The reliability test will fail if the system encounters issues under predetermined circumstances. For instance, in a web application, reliability testing ensures that all web pages and links consistently perform without errors, providing a reliable user experience.

For instance, consider a web-based email service focused on ensuring the reliability of its core functions — sending and receiving emails. High user activity is simulated in a continuous 72-hour test, including attaching files and marking emails as spam.

Specific scenarios, such as sudden spikes in user activity or temporary server outages, are introduced to evaluate the system’s response. This reliability testing aims to confirm error-free email transactions and the system’s capability to handle diverse user activities seamlessly. If the test uncovers issues, further investigation and improvements are undertaken to enhance the system’s reliability.

• Security testing

This testing process protects the software program or system from unauthorized access or attacks. Organizations conduct security testing to identify vulnerabilities in the security mechanisms of their information systems.

For instance, consider an e-commerce platform that stores sensitive customer information, including personal details and payment data. Security testing for this platform would involve simulating various security threats, such as attempts to hack into the system, unauthorized access to customer accounts, or exploitation of potential vulnerabilities in the website’s code.

Types of Automation Testing Frameworks

Automation testing frameworks provide guidelines for automated testing processes. These frameworks define the organization and execution of test scripts, making it easier to maintain, scale, and enhance automated testing efforts. Various testing frameworks serve different project requirements and testing objectives based on various advantages in terms of reusability and maintainability.

Below are some automation testing framework types that help developers and testers choose the right framework for their project needs.

• **Linear framework (or Record and Playback): **This is a basic framework where testers write and test scripts for individual cases, like recording and playing back actions on a screen. It’s commonly used by larger teams and those new to test automation. Understand the distinction between scripting testing and record & replay testing with tools like Selenium IDE and Katalon.

• Modular-based framework: Suitable to its name, we use this framework to organize each test case into tiny parts known as modules, where the modules are quite independent. These modules are handled uniformly using a master script, saving time and optimizing workflow. However, you would need prior planning, as well as expertise, to implement this framework.

• Library architecture framework: Built on a modular framework, this approach breaks down test cases and groups tasks within a script into different functions stored in a library. While enhancing reusability and flexibility, it demands more time and expertise to set up. This framework enhances reusability and flexibility but requires more time and expertise.

• Data-driven framework: A Data-driven framework is one in which test cases are written around a dataset rather than a set of steps. This can be useful if a project is under time pressure or has enormous test cases. With this framework, the test cases can be executed by anyone with access to the data as long as they can import it into their platform. The typical data-driven framework will include a suite of test steps, each containing all the information needed to execute that step against a dataset.

• Keyword-driven framework: A Keyword-driven framework is a software design pattern in which the implementation of a system is separated from its specification and implementation. The specification is expressed as an interface that contains method names without any associated implementation. The implementation of the specification is represented as an interface stub (or proxy) that contains method implementations but does not expose the code that implements the methods. The code that uses the interfaces to access data and services does not depend on a particular implementation, so it can be changed later.

• Hybrid testing framework: This test automation framework combines manual and automated tests to achieve higher-quality software. The Hybrid Framework builds upon the foundation of Behavior-Driven Development (BDD), Test-Driven Development (TDD), and Acceptance Test-Driven Development (ATDD). Rather than focusing on a single approach, it utilizes BDD’s human-readable feature files, TDD’s unit tests, and ATDD’s acceptance tests.

In the following section, let’s cover some of the most popular automation testing frameworks and tools based on different aspects, such as web-based, performance-based, API-based, and more.

To address this, we commonly use Selenium’s defined waits, such as Implicit and Explicit waits, which help manage synchronization issues during script execution. To learn more about waits, follow this guide on Selenium Waits, which will provide valuable insights with examples for better understanding.

Selection of tool

Selecting the appropriate testing tool can be challenging, given the variety of options, ranging from free tools like Selenium, Cypress, and Playwright to paid ones like TestComplete. Vendors sometimes exaggerate the capabilities of their products, suggesting they are a perfect fit for every situation. This can be confusing, particularly when choosing tools without thorough research and evaluation. To make a wise decision, it’s crucial to establish specific criteria based on the application and insights from experienced users.

Solution:

Conduct a thorough assessment by defining specific testing requirements. Explore and trial various tools, considering community feedback and engage with vendors. Test small projects and evaluate costs, scalability, and integration capabilities. Prioritize training and support quality, and validate tool effectiveness through a proof of concept. Adopt an iterative approach, making adjustments based on evolving testing needs and user feedback.

Diverse testing environments

Ensuring thorough testing for applications across various devices, browsers, and operating systems is a significant challenge for both web and mobile platforms. Users access apps through various OS and platform combinations on different devices, highlighting the need for a robust test automation approach to achieve comprehensive coverage and maintain reliability.

Solution:

Use LambdaTest to overcome this challenge; this platform allows you to access a wide range of real devices, browsers, and OS configurations, making it easier to conduct thorough testing across diverse environments. Furthermore, prioritizing test cases based on critical devices and OS combinations enhances efficiency and maximizes coverage.

Inadequate testing infrastructure

Testing complex applications in various environments, especially with regression tests, is time-consuming. Clients, however, expect quicker product deliveries to stay competitive. This pressure often leads to rushed testing, prioritization issues, and insufficient test coverage, allowing bugs to reach production.

Solution:

To address this, teams should plan and prioritize test cases, evaluating which ones benefit from automation and which require manual execution. Striking a balance between manual and automated testing is key to success. Prioritizing tests helps identify critical areas early, saving time and ensuring thorough testing. Implementing these solutions not only tackles challenges effectively but also streamlines development and testing efforts for the timely delivery of robust applications.

Having inadequate testing infrastructure and maintaining the test infrastructure can be challenging. Consider LambdaTest to provide a scalable and efficient solution to deal with inadequate testing infrastructure by allowing teams to focus on strategic test planning and execution without the burden of managing testing infrastructure. This ensures timely and robust product deliveries while meeting client expectations.

Running your test scripts on the test execution platform is a breeze. With all these features of LambdaTest, you can bring down the test execution time. You can also track the issues and sort them out effectively.

Popup and alert handling

While interacting with a web application, various types of popups and alerts may appear. Examples include browser-level notifications like camera or microphone access requests, web-based alerts such as site notifications or prompts to leave a site, and OS-level pop-ups that Selenium can’t directly handle.

Solution:

For handling browser-level notifications, use ChromeOptions for Chrome and FirefoxOptions/FirefoxProfile for Firefox. Web-based alerts can be managed using Selenium’s built-in Alerts class with methods like accept() and dismiss(). However, Selenium can’t directly handle OS-level pop-ups. For such cases, where pop-ups are considered flash objects, the Robot class is commonly used to interact with them. Combining these approaches is essential to handle different types of web testing pop-ups effectively.

Test case prioritization

Adding more tests slows down the automation testing process, causing delays, missed milestones, and disruptions in release cycles. It’s crucial to prioritize test cases to improve regression testing efficiency.

Solution:

To address this challenge, consider increasing simultaneous test executions or prioritizing which tests to automate first. Prioritization introduces questions about daily, weekly, or less frequent test execution and potential test optimizations for speed. Finding a balance between quality standards, resource conservation, and test case prioritization is challenging but essential for maintaining software reliability within specified timelines.

Now that you have learned almost all about automated testing, it’s time to learn some of its best practices in the following section.

Best Practices for Test Automation

In this section, we will discuss the best practices for automated testing to get the most out of it.

Decide the test cases that might require automation

It’s impossible to automate every test. You need to check what test automation requirements are before automating. Hence, you must sit with your team and prioritize the test cases you need to automate. First, you must set a goal and determine the tests you need to automate.

It’s strongly suggested that you check the app functionality as soon as you add it. You can also take some time to organize your smaller tests into more significant automation tests. Organizing automated tests based on the functionality and major or minor application division is also recommended.

Choose the best automated testing tool

Which testing tool do you need to learn about? This is an answer everyone needs to know, right from beginners who are starting to seek an answer to the question. Even though there are plenty of automation and UI automated testing tools in the market, the tool you choose should be good enough to simplify your tasks and give you the break you need.

Allocate testing tasks wisely

Know your team’s strengths before allocating the tasks. For example, a few team members might be more vital when they write automated test scripts. A few of them might do well when asked to write test cases. Some may excel at writing test reports. Hence, it’s always good to know what your team is good at. To ensure that this happens, team communication is a must. If these tools are integrated with project management tools such as Jira integration and Slack integration, they will help you out, in the long run, to keep your team communication smoother.

High-quality Test Data is mandatory

Test data is mandatory for data driven framework testing. The input data is usually stored as a part of an external file. You can read the data from a database or other sources such as tables, Excel sheets, XML, or text files. The best tool is the one that gets a clear gist of the data file and content and iterates the content while performing automation testing. When you leverage external data, these automation tests become reusable and easy to maintain.
