You can enable/disable the XUnit tests run in parallell during a test execution easily.

    Please follow the below steps to enable / disable the parallel run for the test inside a particular assembly.

    Prerequisites :

    • .Net Core SDK: To create XUnit tests we will need .Net Core SDK. If it is not installed already, please install using the link

    Lets get started : 

    Step 1 : Create a xunit.runner.json file to the root folder of the test project.

    Step 2 : Copy paste the below data in to the file.

    {
    “parallelizeTestCollections”:false
    }

    false : this will disable the parallelize run of XUnit tests.
