Display Names

If you want simple control over the name of a test, you can use the [DisplayName(...)] attribute.

    [Test]
    [DisplayName("My first test!")]
    public async Task Test()
    {
        ...
    }

This is also able to reference parameters by using $parameterName within the attribute.

    [Test]
    [Arguments("foo", 1, true)]
    [Arguments("bar", 2, false)]
    [DisplayName("Test with: $value1 $value2 $value3!")]
    public async Task Test3(string value1, int value2, bool value3)
    {
        ...
    }

The above would generate two test cases with their respective display name as:

"Test with: foo 1 True"
"Test with: bar 2 False"

If you have custom classes, you can combine this with Argument Formatters to specify how to show them.

Custom Logic

If you want to have more control over how your test names are, you can create an attribute that inherits from DisplayNameFormatterAttribute.

There you will find a method that you must override: FormatDisplayName. Here you have access to all the arguments and test details via the TestContext parameter.

Then simply add that custom attribute to your test.
