If you use NUnit's Order attribute, you can specify an exact order (dependencies) for the tests to run, which also works with NCrunch:

https://docs.nunit.org/articles/nunit/writing-tests/attributes/order.html

In the NCrunch window, the tests are however always sorted alphabetically, which makes not much sense, given they are run in a different order. They are just hard to find then e.g.
It would be nice if you could order them non-alphabetically by order instead.
