XUnit – Part 8: Using TheoryData Instead of MemberData and ClassData

XUnit – Part 5: Share Test Context With IClassFixture and ICollectionFixture
xUnit has different mechanisms to share test context and dependencies. Not only it allows us to share different dependencies between tests, but also between multiple test classes. We can also choose to get a fresh set of data every time for our test. So in this post, I’m going to go though those mechanism with …
XUnit – Part 4: Parallelism and Custom Test Collections

So by release of xUnit 2, we have the ability to run the tests in parallel. In this version, the tests are gathered into collection, and …
XUnit – Part 3: Action Based Assertions Assert.Raises and Assert.Throws
