You can run a subset of tests or view a subset of test results by filtering test tags. Tags are a property of the test case, test suite, or test file.
Add comma-separated tags to the Tags section in the Test Browser. Tags cannot contain spaces; spaces are corrected to commas.
In the text box at the top of the Test Browser or
Results and Artifacts pane, filter tests by
tags: id1, id2, ... where
id2 are example test tags. Enter multiple tags
separated by commas to return tests containing
any tag in the list.
To run a subset of tests
Filter the tests using tags.
In the toolstrip, click the down arrow below Run and select Run Filtered.
