xUnit run all tests under tests folder

Question

Is there any way (apart from this .NET Core 1.0 - How to run "All tests in Solution" with xUnit command line) to run all unit tests using xUnit through VS Code? I have created the following task:

    {
        "taskName": "test",
        "args": [
            "./tests/Project1.UnitTests"
        ],
        "isTestCommand": true,
        "showOutput": "always",
    }

However I'd like to pass in the args something like "./tests/*.UnitTests so that every time I add a new test project the task picks this up. Is that currently possible?
