What are my options to

问题 xUnit offers the concept of (shared) class fixtures as explained in Shared Context between Tests. What I didn't figure out so far is if there is a way of parametrizing such class fixtures. For example, what if the DatabaseFixture should be enriched with some test data which depends on the test it's being run against? A test class might want to insert test data but only once and then run all its tests against that database (fixture). In other words, what if the // ... initialize data in the
