Debugging in IDE
- Setting Breakpoints: Breakpoints are markers that pause the execution of the test script at a specific line of code. In Selenium IDE, you can set breakpoints by clicking on the line number in the script editor or by right-clicking on the line and selecting "Toggle Breakpoint." This allows you to stop the execution at specific points to examine variables, step through the code, and analyze the flow.
- Stepping Through Execution: Once a breakpoint is set and the test script is executed, Selenium IDE will pause at that breakpoint. You can then use the debugging controls provided in the IDE, such as "Step Over" (to execute the next command), "Step Into" (to dive into a function or method), and "Step Out" (to exit the current function or method). These controls allow you to navigate through the script line by line, observing the changes and behaviour of elements and variables.
- Inspecting Variables and Elements: While debugging, you can inspect the values of variables and the state of web elements. Selenium IDE provides a debugging console or an interactive panel where you can view and evaluate variables, execute JavaScript expressions, and inspect the properties and attributes of elements on the web page. This helps in understanding and diagnosing any issues encountered during test execution.
