Test automation uses software tools to create, execute, manage, and report software tests. It replaces many manual tasks. Test automation is often used for regression tests, which are repetitive actions, and for both functional and non-functional testing.

Test Automation Examples

• A tester uses a tool to automate the testing of a web application’s user interface. He records the actions of clicking on buttons, entering test data, and validating outputs. He then replays the recorded script to test the application on different browsers and devices.
• A tester uses a tool to automate the testing of a software's compatibility with with different operating systems, browsers, and browser versions. He creates the test automation scripts in a programming language. He then executes the test scripts and analyzes the results.
  
• A tester uses a tool to automate the testing of a mobile application’s performance. He sets up the parameters of load, concurrency, and duration. He then runs the test and monitors the response time, throughput, and resource utilization of the system.
• A tester uses a tool to automate the testing of an e-commerce application’s security. He creates test cases to check for vulnerabilities such as SQL injection, cross-site scripting, and broken authentication. He then executes the test cases and reports the findings.

Tips for Test Automation

• Evaluate and choose a suitable test automation tool that meets your software requirements, skill level, and budget.
• Define a test automation strategy (in your test plan) that aligns with your scope, testing objectives, and resources.
• Design and develop reusable, maintainable, and modular test scripts that follow automation coding standards and automation design patterns.
• Execute test automation regularly and continuously as part of your software test life cycle.
• Analyze test automation results and metrics to identify defects in test automation, and improvement opportunities.
