This topic provides information about debugging tests and consists of the following sections:
Debug Recorded Tests #
TestCafe Studio's debug mode helps you understand what is happening on your web page during testing. In this mode, TestCafe Studio pauses the test and allows you to debug the tested page using the browser's developer tools. You can check the web page's state, DOM elements' location, their CSS styles, etc.
You can activate the debug mode in one of the following ways:
Add the Debug action to a particular position of a test. The test is paused when the test reaches this action.
Enable the Debug mode option for a run configuration in the Run Configurations dialog. In this case, the test is paused before the first test action.
Enable the Pause the test when it fails option for a run configuration in the Run Configurations dialog. TestCafe Studio automatically enters the debug mode when the test fails.
Once the test is paused, you can open browser's developer tools and debug.
During debugging, the browser window displays a footer with the following buttons:
- The Unlock Page button unlocks the tested page and allows you to interact with its elements.
- The Resume button resumes the test.
- The Next Action button allows you to skip to the next test action.
Debugging Features #
TestCafe Studio includes features that help you find the cause of issues in your tests.
TestCafe Studio can capture screenshots during a test. You can analyze these screenshots to determine the cause of issues.
There are two ways to take screenshots:
Use the Take Screenshot action to take a screenshot in a particular place in a test.
Turn on the Take a screenshot if a test fails option for a run configuration in the Run Configurations dialog to take a screenshot when a test fails.
TestCafe Studio stores the screenshots in the directory specified in the Run Configurations dialog and displays them in test reports.
Test Speed #
Tests are executed at full speed with minimum delays between actions. You can adjust the speed in one of the following ways:
Use the Set Test Speed action. The action parameter allows you to specify the test speed from 1 to 0.01.
Change the Speed option's value in the Run Configurations dialog's Advanced Options section.
Debug Coded Tests #
See Debugging in TestCafe documentation for more information about debugging coded tests.
