Pass multiple tests names in "dotnet test --filter" option

Question

I am trying to rerun failed tests using dotnet test command. I want to pass a list of failed tests from a file created during test run. I can't seem to get the '&' operator syntax right for the "--filter" option. I am able to pass only one test name per run. Example: dotnet test --filter "FullyQualifiedName~TestOne1 & FullyQualifiedName~TestOne2"

Answer 1

Think of the text you write into the filter like evaluating a boolean. None of your tests' FullyQualifiedName can be TestOne1 AND TestOne2 at the same time.

Try using the | (OR) operator instead like this:

dotnet test --filter "FullyQualifiedName~TestOne1 | FullyQualifiedName~TestOne2"

This way your test's FullyQualifiedName can be like TestOne1 OR TestOne2.
