ParallelTestingSample-dotnet-core

This .NET 10 parallel testing sample uses --list-tests and --filter parameters of dotnet test to slice the tests. The tests are run using the NUnit.

This sample has the 100 tests, and slices them to 20 tests in 5 jobs. You can see the pipeline behavior result by clicking the build status badge above.

Make slicing condition

• Get test name list of all tests by using --list-tests parameter and grep Test_
• create_slicing_filter_condition.sh makes filter condition to slice the tests, and set into $(targetTestsFilter)

 - bash: | tests=($(dotnet test . --no-build --list-tests | grep Test_)) . 'create_slicing_filter_condition.sh' $tests displayName: 'Create slicing filter condition'

Run tests using slicing condition

command: testprojects: '**/*Tests/*Tests.csproj'arguments: '--no-build --filter "$(targetTestsFilter)"'
