** Branch linked: lp:nunitv2 -- NUnit throws NullReferenceException when return null from ISuiteBuilder.BuildFrom(Type) method https://bugs.launchpad.net/bugs/600555 You received this bug notification because you are a member of NUnit Developers, which is subscribed to NUnit V2.
Status in NUnit V2 Test Framework: Fix Committed Bug description: Version: 2.5.5, GUI Runner On the NUnit-site the documentation regarding the ISuiteBuilder- interface is as follows (http://www.nunit.org/index.php?p=suiteBuilders&r=2.5.5): "CanBuildFrom should return true if the specified Type is one from which the builder is able to create a fixture. This usually involve examining the Type and its attributes. The BuildFrom method should return a test fixture completely populated with its contained test cases. Return null if it is not possible to build a fixture using the provided Type." However, when a custom implementation of the ISuiteBuilder-interface returns NULL after calling the BuildFrom(Type)-method, a NullReferenceException is thrown: System.NullReferenceException...
