I am running C# unit tests in Visual Studio 2015 using Resharper 10.0.2 and NUnit 3.7.1. I have several test classes. When I run each test class individually, they all pass. When I run the entire suite of tests, one particular class hangs. The test class that hangs contains several tests. If I comment out all tests except one particular test, then the entire suite will pass. If I uncomment any individual unit test previously commented out, then the class hangs. I have debugged each individual unit test and none of them hang or cause any exception.
Two other colleagues have the same experience running my unit tests in their environments. I am not trying to run in parallel (number of assemblies to run in parallel = 1).
Any suggestions to diagnose the problem?
