Cannot find Assert.Fail and Assert.Pass or equivalent

Question

I used to use these in NUnit and they are really useful. Any idea how to do something like that?

EDIT, CODE SAMPLE:

        bool condition = false;//woul         


        

Answer 1

An alternative to Assert.Fail("messsage") suggested by xUnit docs

xUnit.net alternative: Assert.True(false, "message")

has a downside – its output is

message

Expected: True
Actual:   False

To get rid of

Expected: True
Actual:   False

don't call Assert.True(false, "message") throw Xunit.Sdk.XunitException instead.
For example, create a helper method similar to this:

public static class MyAssert
{
    public static void Fail(string message)
        => throw new Xunit.Sdk.XunitException(message);
}
