Unit Test Runner Window

Unit test running is performed in Unit Test Runner window. The window appears automatically when you run tests from the code editor or from Solution Explorer. You can also open the window by selecting ReSharper | Window | Unit Test Runner.

Unit Test Tree view

The Test Tree View is populated with all tests contained in the assembly (or assemblies) being tested. Each tree node is marked with an icon showing its state (see the Node Icons table for details).

In addition to viewing the structure of the tree, from this view you can navigate to the source code of a test or test class, or start running, debugging or profiling tests. You can do the following with a test or test class node:

right-click, then click Run, Debug or Profile to perform the respective action on the test or test class;
right-click, then click View Source to navigate to its source code;
double-click to navigate directly to its source code.

The same commands are also available via the toolbar buttons located above the tree view (see Toolbar).

Tree view tabs

The Test Tree View has two additional tabs for displaying failed tests and ignored tests. The number in parentheses shows the number of tests contained in the corresponding tab.

The Failed tab is a rendering of the same test tree filtered to show only the failed tests.

The Ignored tab filters the test tree to show all tests that were ignored, i.e. those that had an ignore attribute (depending on the unit test framework). Ignored tests are normally skipped when running tests. However, an ignored test or test class can still be run individually from Unit Test Runner window or from the code editor.

Node Icons

The colored icons at each tree node represent the test run state:

Description	For individual test nodes	For nodes other than tests
green	The test passed successfully	All tests inside this node passed successfully
red	The test failed	At least one of the tests inside this node failed
yellow	The test was ignored	All tests were ignored inside this node
red, crossed	Test run was aborted	Test execution was aborted somewhere inside this node
grey	The test has not run	No tests were run inside this node
green, with question mark	The test passed successfully the last time it ran, but the code has been modified and recompiled since then	At least one test inside this node failed the last time it ran, but the code has been modified and recompiled since then
red, with question mark	The test failed the last time it ran, but the code has been modified and recompiled since then	All tests inside this node passed successfully during the last time it ran, but the code has been modified and recompiled since then

Toolbar

Toolbar buttons are explained in the following table:

Button	Name	Action
	Navigate to Source	Navigates to the source code for the selected test or test class
	Build Projects	Re-builds all tests currently loaded into Unit Test Runner Note: Once an assembly is loaded into Unit Test Runner, any changes introduced in the code since the last compilation will NOT take effect when running or debugging tests from Unit Test Runner window. Use Build Projects to take any changes into account and update the build. Alternatively, you can run or debug tests from the code editor or from Solution Explorer.
	Run All Tests	No tests were run inside this node
	Run Selected Test	Runs the selected test or all tests of the selected assembly, namespace or test class
	Debug Selected Test	Debugs the selected test or all tests of the selected assembly, namespace or test class
	Profile Selected Test	Opens an instance of dotTrace Profiler and automatically profiles the selected Note: A current version of dotTrace Profiler must be installed on your system.
	Stop Execution	Aborts any ongoing test execution
	Track Running Test	Is used to track the currently running test by highlighting its node in the tree view
	Hierarchical View	Toggles the tree viewing mode: shows the hierarchy of assemblies, namespaces and test classes
	Plain View	Toggles the tree viewing mode: shows only the test classes with their respective tests
	View by Category	Toggles the tree viewing mode: shows all test classes with their respectives tests by category (a test may appear several times in the tree, once for each category)

Progress Bar and Diagnostics

The progress bar shows the progress of the current test run.

In addition, its color reveals the overall status of the run:

green color stands for ongoing success so far in the run;
red signifies failure;
yellow means that the run has been aborted;

The diagnostics message below the progress bar offers a short summary of the test run. If the run is in progress, it refers to the test running currently. If the run has stopped, it refers to the test currently selected in the tree view.

The diagnostics message will usually be "Success", "Some tests failed", "Execution aborted" or "Ignored". However, if the current node is a failed test, the diagnostics message will provide the type of the exception that occurred:

Output and Statistics Views

The Output View displays console output and exception stack traces produced during the test execution for the test currently selected or currently running. If the current tree node is not a leaf node, output is aggregate for all of the node's children.

Sample output is given below:

The message indicates the discrepancy between target output and actual output. It also provides a link to the code statement where the error occurred. You can click the link to navigate to the corresponding line in the source code.

The Click to View Difference button displays a window showing the exact difference in the target output and the actual output such as shown below:

Statistics View

The statistics view lists time measurements for the currently selected test or for all its children. Duration of test runs may vary depending on CPU usage at run time.
