- When I create my C# project being put in a network mapped drive, Pex doesn't work

- Solution: Right click on the project in the Solution Explorer -> Pex -> Create Parametrized Unit Test Stubs, and then fill in your Pex test methods there

- How can I instruct Pex to measure the coverage of my class under test Foo?
- [PexClass(typeof(Foo))] sets Foo as the Type Under Test for the class. Pex uses that to tune various settings.
- How can I use set up and tear down methods in my Pex test class?
- Pex does not monitor set up or tear down methods. Whatever you do in those methods will not be understood by Pex. You can simply keep calling the set up method at the start of each Pex test method or the tear down method at the end of each Pex test method.
- When I create a factory method for a class, Pex doesn't recognize my factory method.
- It is very likely that the class is one from the .NET base library (not a user-defined one). Currently Pex doesn't recognize factory methods for a class from the .NET base library.
