Exception running unit tests with Fakes on build server

Question

I am getting the following error

Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.UnitTestIsolationException: UnitTestIsolation instrumentation failed to initialize. Please restart Visual Studio and rerun this test

I have VS2012 and they run locally fine. Build server is TFS2012. I have tried using the DefaultTemplate.11.1.xaml and also removing the reference to the test settings file.

I'm running out of ideas now, so any help welcomed.

Answer 1

Are you using mstest or the Visual Studio Test Runner? According to https://stackoverflow.com/a/15608129/270348 , the latter is required.

Answer 2

删除testsettings文件 - 即使它没有被引用，它仍然会影响正在发生的事情（请参阅https://stackoverflow.com/a/17111357/270348 ）
