I have a nunit 2.5.10 parameterized test:
public class MyTest : BaseTest
public MyTest(string arg)
//... test stuff
In VS 12 with Resharper 7.0.1 I run only one fixture but! the constructor is called twice - once before test execution (for one parameter) and then after test execution but for another parameter. Why? Only constructor is called twice, test itsself is running as expected - only one time.
it's a known problem, unfortunately, see RSRP-336641 "When calling certain case on Parametrized TestFixture all cases constructors and TestFixtureSetUp are called."
