Unit Test Sessions window
Ctrl+Alt+R
dotCover runs unit tests in the Unit Test Sessions window. The window appears automatically when you run tests from the current document or from the project or solution. For more information, see Using Unit Test Sessions.
The window is designed to help you run any number of unit test sessions, simultaneously and independently of each other. Sessions can be composed of any combination of tests. In the debugging mode, only one session can be run at a time.
The unit test tree shows the structure of tests belonging to a session, which you can filter to show only passed, failed or ignored unit tests. You can navigate to the code of any unit test by double-clicking it.
Status Bar and Progress Bar
The progress bar and the status bar under the toolbar display the current progress. On the status bar, you can see the total number of tests in the session as well as number of tests in different states: 
Control | Name | Description |
|---|---|---|
| All Tests | Show all tests in the current test session. |
| Passed Tests | Only show successful tests and hide all other tests. |
| Failed Tests | Only show failed tests and hide all other tests. |
| Ignored Tests | Only show ignored tests and hide all other tests. A test is ignored if it has the corresponding attribute, or if the whole category where it belongs is ignored. |
| Unknown Tests | Only show tests that either were not executed or have changed since the last execution. |
| Execution log | Lets you see either the number of test execution errors (related to the execution process, not tests themselves) or shows OK if there are no errors. |
Window tabs
When unit test sessions open in the window, they are displayed in new tabs, which show up on the left. The previously open tabs move to the right if the width of the window allows, otherwise they unload themselves saving memory - but you can always restore them by clicking the arrow that appears to the right of the tabs and clicking the required tab:
To prevent a tab from unloading, click the pin icon 
next to the tab title.
