Need for Automation in Software Testing

In the fast-paced technology industry, manual testing doesn’t fit right for businesses looking for fast and short testing cycles, easy deployment, exceptional performance, and better integration. Does that mean the development team should compromise on quality to fall behind deadlines? No, and the game-changer alternative has always been to implement automation in software testing. We can have an example of Google, which uses a custom internal testing framework named Bazel that combines test automation, integration, and UI testing.

Let’s dive into the blog to understand automation in software testing and how it can enhance reliability, quality, and speed for software deployment.

What is Automation Testing in Software Testing?

Automation testing in software testing is the method of conducting tests through automation software and tools. Following the best practices for testing, it supports the execution of pre-scripted tests before the production release. Integrating automation will help to validate functionalities, reliability, and performance of the software to meet expected standards and requirements.

Automation for different types of software testing broadens the scope through comprehensive test suites for every feature and functionality. In complex scenarios, manual testing can be too tedious and difficult to perform, while automation delivers faster results, accuracy, promptly debugs, and deploys high-quality software.

Critical Areas to Implement Automation

Automation has transformed software testing with a multitude of software and tools that fit your specific business needs. Before making the decision, it is crucial to understand which part of your software testing needs to implement automation. Whether you are targeting functional or non-functional testing, you should consider key areas where automation is required:

Predictable Workflows

Implementing automation for predictable workflows saves time and reduces manual errors for rule-based tasks that don’t frequently change. This ensures more stability with the standard sequence for user experience, while freeing the QA team to focus on other complex scenarios.

Example: eCommerce websites are automating the login process, checkout, and product search following predictable workflows.

Core Business Logic

It comprises functionalities that directly affect business operations and user experiences. Automation ensures that after every code update, these tests ensure for critical component function without any human intervention. Majorly for the part where security and financial risk are involved.

Example: Fintech businesses use this automation for payment processing to ensure every transaction calculates the right fees, interest, and secure payouts.

Regression-Sensitive Areas

These are the areas where changes can directly impact existing features. Automation for regression testing ensures that new code does not break old functionalities, allowing the team to release updates without compromising software integrity.

Example: Any changes to the user profile, like contact number or address, can directly impact the dashboard and the notification system. So, automation regression testing can quickly verify that features allow it to remain functional.

Cross-Platform Compatibility

For software testing, checking for cross-platform compatibility ensures the application performs consistently across different browsers, operating systems, and devices. Testers often use automation tools like BrowserStack and Selenium Grid to simulate different scenarios and execute test cases.

Example: A banking application uses automation to test for UI/UX issues, reducing manual efforts, it ensures the features work consistently across MacOS, Windows, iOS, and Android.

Performance and Load Testing

It signifies how your software will perform depending on user traffic and different levels of data volume. Automation tools like Gatling and JMeter can simulate 1000+ virtual users to access the system. Checking for load testing ensures that the platform remains stable.

Example: A Movie Ticket booking platform like BookMyShow requires automated testing to handle peak traffic during the festival season.

CI/CD Integration

Integrating automation for Continuous Deployment/Continuous Integration (CI/CD) ensures real-time quality checks. It can minimise the risk of defective code before production, supporting rapid development cycles. Tools like CircleCI, Jenkins, or Gitlab CI are used to execute automated test suites.

Example: Food delivery platforms like Zomato and Swiggy, developers can push new updates for the coupon system and restaurant filters. Automation testing helps to test for changes using tools like Jenkins or GitHub promptly.

Top Benefits of Using Automation Software Testing

Automation in software testing does not replace humans entirely, but it can level up for the majority of components to improve efficiency, software quality, and faster deployment. Compared to manual testing, it can provide a range of benefits, including:

Improved Testing Cycles

For software testing, automation can bridge the timeline between software development and deployment. It can accelerate the testing process to execute faster than manual efforts, for faster feedback, which can reduce the release cycle from weeks to days for competitive industries where user demands change rapidly.

Better Test Coverage

Automation testing allows for the execution of large volume test cases across multiple data inputs, environments, and devices. Trying that with manual testing would be time-consuming and increase the risk of errors, but an automated process enhances the depth of test coverage.

Consistency and Accuracy

Automated tests operate through tools and software that guarantee each test is performed consistently with constant logic. Also, it can validate results against the estimated outcomes without any risk or deviation. Throughout the process, it provides accurate results, eliminating all bias.

Scalability

Most QA teams struggle with scalability due to manual testing, but with automation, it becomes easy to perform parallel test execution for scaling testing efforts. Live streaming platforms use this to run 1000+ automated tests simultaneously across multiple devices, browsers, and applications.

Early Detection for Defects

Integrating test automation in software testing allows earlier detection of bugs before it gets finally deployed. Software where new features are frequently added should automate unit and integration tests for detecting errors in coding. So, bugs get easily detected before reaching out to the QA and production teams.

DevOps and Agile Practices

In case your QA team requires rapid iterations and continuous integration, automation for software testing syncs with agile and DevOps models. Automated test suites ensure a quality check for every sprint to maintain quality with shortened development timelines.

Automation Best Practices in Software Testing

The software industry has been evolving with frequent updates for languages, frameworks, and technologies. Following the QA best practices, testers can deploy faster with quality features, and software implements test automation.

Design Reusable and Modular Test Scripts

It is advisable to create automated test scripts for modular functions that can be reused and applied to different scenarios. It can simplify maintenance and reduce data redundancy. Also, to abstract details from web pages, you can implement design patterns like the Page Object Model.

Data-Driven Testing

QA teams can store their testing data in databases and external files rather than test scripts. It helps to run the same test for different data sets, also manage data-driven frameworks to improve test coverage and flexibility.

Continuous Integration

Integrating an automated test framework into CI/CD pipelines will automatically run tests for each code change. It helps to track progress with setting up notifications and dashboards to identify test failures and issues.

Parallel Testing

Following the parallel test across multiple browsers or devices to reduce execution time and improve efficiencies. It can optimise tests under different environments to ensure better coverage and catch defects.
