Repeating

If you want to repeat a test, add a [RepeatAttribute] onto your test method or class. This takes an int of how many times you'd like to repeat. Each repeat will show in the test explorer as a new test.

This can be used on base classes and inherited to affect all tests in sub-classes.

using TUnit.Core;

namespace MyTestProject;

public class MyTestClass
{
    [Test]
    [Repeat(3)]
    public async Task MyTest()
    {
        
    }
}

Global Repeat

In case you want to apply the repeat logic to all tests in a project, you can add the attribute on the assembly level.

[assembly: Repeat(3)]

Or you can apply the repeat policy on all the tests in a class like this:

[Repeat(3)]
public class MyTestClass
{
}

The more specific attribute will always override the more general one. For example, the [Repeat(3)] on a method will override the [Repeat(5)] on the class, which in turn will override the [Repeat(7)] on the assembly.

So the order of precedence is:

1. Method
2. Class
3. Assembly
