Yaml: How to exclude some tests in VSTest@2

To exclude specific tests using VSTest@2, you can leverage the testAssemblyVer2 input property in conjunction with the | notation to define multiple patterns.

- task: VSTest@2 inputs: testSelector: 'testAssemblies' # note the | testAssemblyVer2: | **\*_uTest.exe !**\*BBE*

In this example:

• **\*_uTest.exe: This pattern matches all files ending with _uTest.exe in any folder.
• !**\*BBE*: This pattern excludes any file or folder containing BBE in its name.

The | notation is crucial here as it allows you to specify multiple patterns on different lines. Without it, all lines would be treated as a single input, resulting in incorrect behavior.

Alternatively, you can use the testFiltercriteria input property to exclude specific tests based on their fully qualified name:

- task: VSTest@2 inputs: testSelector: 'testAssemblies' testAssemblyVer2: | **\*_AlluTests.dll testFiltercriteria: 'FullyQualifiedName!~TestCase1&FullyQualifiedName!~TestCase2'

Here, the testFiltercriteria is set to FullyQualifiedName!~TestCase1&FullyQualifiedName!~TestCase2, which excludes tests with the fully qualified names TestCase1 and TestCase2.
