In this series of five articles, I want to help you get started with using SpecFlow in your test automation project. Because we’re not duplicating cases, this approach does not slow down the feedback for the larger test run. That’s not ideal, since it would create duplicated cases and slow down feedback for the full test run. As your SpecFlow project grows in size, you might find yourself repeating specific scenarios, or parts of it, as you add more feature files. Last week I announced a new series of articles dedicated to Specflow (Behavior Driven Development for .NET).In my first publication, I showed you how to create a simple test using the framework.

See our SpecFlow example repository for a simple example on how to run SpecFlow tests in parallel on TestingBot. Only faster and much more reliable :-). That is, tests should be runnable in any given order and the result of a test should not depend on the outcome of one or more previous tests.
