No parallel tests with xUnit DNX

Question

I'm trying execute my tests one by one, without parallel.

I tried to configure that on my xunit.runner.json file, but without success:

{
  "maxParallelThreads": 1,
  "parallelizeAssembly": false,
  "parallelizeTestCollections": false,
  "preEnumerateTheories": false
}

What am I doing wrong?

Answer 1

I'm on dnx 1.0.0-rc1-final, xunit 2.1.0, xunit.runner.dnx 2.1.0-rc1-build204, and the maxParallelThreads setting in xunit.runner.json is working for me from the command line.

Do you have your tests separated by collections? According to the docs:

By default, each test class is a unique test collection.

So given some contrived "tests" like these, it should be easy to see if they run in parallel or not:

With:

{
    "diagnosticMessages": true,
    "maxParallelThreads":  4
}

With:

{
    "diagnosticMessages": true,
    "maxParallelThreads":  1
}
