CLion 2020.3 Help

Test Runner tab

The Test Runner tab opens in the Run tool window when a testing session begins, and features the same toolbar buttons.

Test runner tab
  1. The run toolbar is almost the same as that for the Run tool window, but features testing-specific buttons.

  2. The left-hand pane shows the tree view of all tests within the current run/debug configuration.

    • The root node represents the test selected to run.

    • The nested nodes represent the hierarchy of test suites and test cases.

    • The leaf nodes represent the individual tests.

    The status of each test is indicated by an icon. Double-click a node to open the respective test class or test method in the editor.

  3. The inline statistics show the list of executed tests with the execution time of each test.

  4. The testing toolbar provides controls that enable you to monitor the tests and analyze results. Some of the commands are duplicated on the context menus of the test tree nodes.

  5. The output pane shows the output of the current test suit.

Test HistoryTest History

Open the list of internally saved results of test sessions. Each item is supplied with the name of the run configuration and a time stamp.

To view the results of a testing session from the CLion history, select the item with the suitable run configuration and time stamp. The loaded test results are shown in a new tab, and the name of the corresponding run configuration is displayed in the title bar.

To re-run the tests from the loaded session, click Rerun.

Import Tests from FileImport Tests from FileLoad previously exported test results. This button opens a dialog in which you can select the required XML file with test results.

Click this cog button to access the context menu with the following options:

  • Track Running Test: turn this option on to monitor execution of the current test. If a test suite contains multiple tests, the tree view of tests expands to show sequential test methods, as they are executed.

  • Show Inline Statistics: turn this option on to have the statistics shown next to a test result, displaying the time used for executing each test.

  • Scroll to Stack Trace: turn this option on to have the console scroll to the beginning of the trace of the last failed test.
    If you click the root node (the test package) in the tree view with this option turned off, the console will show the very beginning of the test.

    This option is helpful when a test package contains multiple test classes and test methods. If some of the tests fail, you can scroll in the console to the beginning of a stack trace of an exception or assertion.

  • Open Source at Exception: use this option to explore the results of a test that fails as an error, throwing an uncaught exception.
    If you double-click the failed test class or method in the tree view with this option turned on, the respective test class or method will open in the editor, with the caret placed at the line that caused the problem.

  • Navigate with Single Click: turn this option on to have the currently selected test in the tree view synchronized with the editor automatically.

  • Set Auto Test Delay: point to this node to reveal the list of available delays between file saving and rerunning tests. The selected value gets the check mark.

  • Select First Failed Test When Finished: turn this option on to have the first failed test automatically selected in the tree view upon completing the tests.
