Explore test results
After IntelliJ IDEA finishes running your tests, it shows the results in the Run tool window on the Test Runner tab.
The console on the right shows the output of the current test session. It allows you to see the detailed information on the test execution and why your tests failed or were ignored.
The Test Runner toolbar located above the list of test results allows you to show and hide successful and ignored tests, display how much time it took to run each test, export, import, and sort test results.
Next to each test on the Test Runner tab, the IDE displays an icon that marks the test status:
|Test error. This status is assigned to tests that caused an exception from the tested source code.|
|Test failed. If at least one child test fails, all its parent tests are marked as failed.|
|Test in progress.|
|Test passed successfully.|
Test terminated. This status is assigned to tests that were stopped.
If at least one test receives this status, then all unfinished tests and their parent tests are marked as terminated.
Sort and filter test results
Use the following options on the Test Runner toolbar if you want to focus only on the failed tests or if you want to reorganize test results:
Disable the Show Passed option to hide successful tests.
Disable the Show Ignored option to hide ignored tests.
Click to sort test results alphabetically.
Click to sort test results by duration.
Track test execution
In IntelliJ IDEA, you can monitor execution of the current test. If a test suite contains multiple tests, the list of tests expands to show test methods as they run one by one.
To monitor test execution, click on the Test Runner toolbar and enable the Track Running Test option.
Manage test results
Click on the Test Runner toolbar and enable the following options:
Scroll to Stack Trace: if a test produced a lot of output (for example, logging) before failing, this option automatically scrolls the output console to the assertion failure once you select the test on the Test Runner tab.
Open Source at Exception: if you double-click a failed test method on the Test Runner tab with this option on, the editor will scroll to the line on which the exception was thrown (instead of scrolling to the test method declaration).
Navigate with Single Click: open the code for the selected test automatically in the editor.
Select First Failed Test When Finished: automatically select the first failed test in the list upon completing the test session.
Include Non-Started Tests into Rerun Failed: if some tests were ignored or not started during the previous test run, this option executes them together with the failed tests when you click (Rerun Failed Tests ).
To view the execution time for tests, click on the Test Runner toolbar and enable the Show Inline Statistics option.
Jump to test declaration
Select the necessary test from the list on the Test Runner tab and press F4.
View assertEquals difference
If a unit test contains string
assertEquals failures, the IDE enables you to compare the strings and view the differences.
Right-click the necessary test and select Differences viewer.from the context menu. You will be able to compare strings in the dedicated
View results of previous tests
IntelliJ IDEA automatically saves results of the last 10 tests. To open the list of recent tests:
Export and import test results
Export test results to a file
Click on the Test Runner toolbar.
Select the format in which you want to save the file: HTML, XML (use this format if you want to import this file later to IntelliJ IDEA), or Custom, apply XSL template (click next to this option and select the *.xsl code style definition file).
Specify the name of the output file and its location.
If you want to open the file in your browser after you export it, select the Open exported file in browser checkbox. Click OK.
Import test results
To load a previously exported file, click on the Test Runner toolbar.
In the dialog that opens, select the .xml file with test results and click Open.
