To make execution in a specific sequence, we have to add the Order property in the hook attribute. Depending on the type of the hook the parameters are resolved from a container with the corresponding lifecycle. The one exception that my team encountered is when you have multiple test projects in the same solution, but that was a convenience thing for us and I do not advise it.

SpecFlow+ Runner supports parallel execution with AppDomain, SharedAppDomain and Process isolation. Only the thread-local state is isolated. I would highly advise looking into dependency injection and how SpecFlow handles it since (with the exception of some unhelpful error handling when you have a very odd error) it works very well for Selenium testing. The method it is applicable to should be static. As of SpecFlow version 2.0, you can run scenarios in parallel. ncdu: What's going on with this second size column?

The rules to be followed for Step Definition methods are listed below . It points to the header of the Examples table. If you need to execute specific steps once per test run, rather than once per thread, you can do this using deployment transformations. If we are executing tests from more than one thread with SpecFlow+ Runner, the After and Before hooks like the BeforeTestRun and AfterTestRun are run only once for each thread. The higher the isolation of the parallel tests the smaller the likelihood of conflicts on shared state and dependencies, but at the same time the higher the execution time and amount of resources needed to maintain the isolated environments. The text was updated successfully, but these errors were encountered: Having hooks on a base class is not a good idea.

Also, we have seen that the Given step has the <> delimiter. In the constructor, we get the pages from the Unity container instead of creating them each time with the new keyword.
