What are the pros and cons to have a seperate project devoted to unit-tests only?

Question

Can you compare the advantages and disadvantages of having all your unit tests in one project devoted to unit-tests only against having your unit-tests residing the relevant assemblies?

Thanks

Answer 1

Advantages to keeping them in seperate assemblies:

• doesn't unnecessarily increase the complexity of the module being tested and doesn't violate separation of concerns.

• you won't need to have your testing framework referenced throughout your solution.

• it will enable (or at least make it easier for you) you to set up your project in a CI environment.
