Debugging Tests
Debugging means finding and fixing problems in your tests. A test failure does not always point to a broken application. Sometimes the test itself has an issue. Debugging helps you identify the cause. One simple way to debug is by checking logs.
Logs tell you what happened during the test. They can show where things went wrong. Another useful method is using breakpoints. Breakpoints stop the test at certain spots. This lets you check the application and test script step by step.
To debug well, stay calm and take it slow. First, run the test again to see the failure. Then, go through each test step carefully. Look for differences between what you expect and what happens. Use screenshots or videos to record the test.
These tools can spot issues you might not notice. Selenium and Appium have debugging features. With Selenium, use browser developer tools to check elements and network activity. Appium offers an inspector for mobile app elements
Tests can fail for many reasons. Network glitches, timing errors, or app changes can trip them up. Always check if the application changed before blaming the test. Debugging gets better with practice. Write down common problems and how you fix them. This builds your skills and makes debugging faster next time.
