Tests Window

The Tests Window should be the most heavily used of NCrunch's tool windows. It takes responsibility for giving a snapshot of the engine output and provides a number of options to help you control how the engine behaves.

The standard tree-view structure should be a familiar from other test runners. NCrunch will also display any build issues against respective projects in the tree.

The buttons at the top of the window (also accessible via right-click) allow you to filter the list of tests. By default, the window is set up to only show failed tests. This is because passing tests are generally of less concern and don't require the same amount of attention.

The light coloured status bar below the toolbar broadcasts useful information about the workings of the NCrunch engine.

Toolbar Options

The options available on the Tests Window toolbar are explained below. Many of these options are also accessible via shortcut key.

Run Tests

This option will queue up the selected tests and add them to the top of the processing queue with a high priority. Note that depending on the state of the engine (and what it happens to be processing at the time), it may be a short while before the selected tests actually start executing. This option is useful if there is a particular test you are interested in and you want to ensure it is processed with the highest priority.

Debug Tests

This option will queue the selected tests with high priority in the processing queue, and mark them for debugging when they execute. Tests that are marked to be debugged will always be executed on the local machine, ignoring any grid servers.

Run All Tests

This option will throw all known tests into the processing queue to be processing in their order as determined by the test pipeline. When the engine is set to run tests automatically, you normally won't need to use this button. When the engine is set to run tests manually, you'll find yourself using it quite often.

Run All Visible Tests

This option will queue up all tests that are currently visible in the tests window - assigning them a high priority. This is a very useful button if you want to re-run all tests that may be presently failing (assuming you have your filters set to show only these tests).


Pressing the Stop button will instruct NCrunch to clear all pending tasks from the processing queue. Any tasks that are still processing will be left in the queue until their processing completes - unless the button is pressed again, in which case these tasks will be immediately killed.


The Reset button is useful if the engine works its way into an inconsistent state - or if you just want to kick the system to have it reprocess everything. The reset button will cause the engine's entire state to be cleared and all processing will restart from scratch. Note that NCrunch will still remember test timings - so the next engine cycle will still have an optimised test pipeline even after a reset.

Ignore Test(s)

This option will allow you to ignore tests so that they are not executed by the NCrunch engine.

Pin Test(s)

The pin tests option allows you to pin tests to the tests window, where they will by-pass all the Tests Window filters and be given a priority boost by the core engine.

Unpin All Tests

This option can be used to immediately unpin all tests from the tests window.

Hide Selected Warning(s)

When warnings have been selected in the tests window, clicking this option will hide them from immediate view. In many ways, this could be considered as 'acknowledging' warnings that are not worth resolving or are not applicable to your situation.

Show All Hidden Warnings

This option will show all warnings that have been hidden from view.

Split Tests Window Vertically

This option changes the Tests Window layout so that the window is split vertically instead of horizontally.

Show Passing Tests

This option is used to filter the list of tests shown to either include (or exclude) tests that are considered to be passing. By default, passing tests are not shown in this view.

Show Failing Tests

As above, but for failing tests. By default, failing tests will be shown in this view. It is dangerous to leave this option turned off while you work, as you may become unaware of tests that are failing.

Show Unexecuted Tests

This option can be used to show/hide tests that have not yet been executed by the engine. Usually this should be left on, as it is often useful to be able to see newly written tests in anticipation of a pass/fail result.

Show Ignored Tests

This option can be used to show/hide tests that are being ignored by the engine. Usually these tests aren't worth looking at - but it's important to be aware of which tests are ignored to prevent breakages you are unaware of.

Group By

The Group By box controls the grouping of all tests and projects shown in the Tests Window. Different grouping options can have certain benefits - for example, grouping tests by category allows you to easily run all tests within a specific category.


The Search Box can be used to filter the list of visible tests and projects in the tree. The search supports the use of wildcards (*) and CamelCase. This means that a search for 'TTS*Test' would bring up a test with the name 'TestTreeSearchOptionsTest'.
