Viewing and Exploring Test Results
Basics
Depending on the selected node in the tree view of tests, the Test Runner displays information on the various levels. In the Test Runner, you can view statistics of the tests, navigate to stack trace, show or hide successful tests, and more.
Use the Testing toolbar to control visual representation of the test results.
View statistics
The Test Runner shows information about the execution time for each test. To view this information, click 
on the toolbar, and then click the Show Inline Statistics option.
The values displayed in the Statistics tab are not accurate and only give an approximate estimate of the test performance. For example, if a garbage collector works during the test run, the memory usage shown in the Statistics tab is wrong.
where:
The run toolbar is almost the same as that for the Run tool window, but features testing-specific buttons.
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.
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.
The output pane shows the output of the current test suit.
The inline statistics show the list of executed tests with the execution time of each test.
Important note
If a unit test contains string assertEqual failures, the test runner provides the ability to view differences between the compared strings. Choose the from the context menu of the failed test that contains assertEquals, and explore differences in the Differences viewer.
