Hence, you would find a lot of similarities between NUnit testing and xUnit testing. Multiple SetUp, OneTimeSetUp, TearDown and OneTimeTearDown methods may exist within a class. The SetUp method in a SetUpFixture is executed once before any of the fixtures contained in its namespace. NUnit allows us to run tests without using a main method.
