Is the test suite setup method executed once for each test, or only once for all?

Question

I know the answer may differ for each test framework. But for the ones you know, what should happen?

Answer 1

In NUnit, you have TestFixtureSetUp which runs only once before all tests in the fixture run and SetUp which runs before each test method is run.

Answer 2

In MSTest you have TestInitializeAttribute

When run in a load test, the method marked with this attribute will run once for every virtual user iteration in the test. If you need to do initialization operations once, that apply to the entire test, use the ClassInitializeAttribute.

AssemblyInitializeAttribute is run once for all tests in all classes.
