And, naturally, there are no FailureReports, and since the BDDFramework was able to call this TestSuiteScreen correctly, there is no ErrorMessage. First, we define a static entity containing all of the examples we defined in the previous section. Server Actions being tested by a test that uses the BDDFramework need to be set to Public. Now we need to create a new app that contains the automated tests. When - describes the specific action/event — in many scenarios there should only be one such step (for example, adding the product to the cart). Cucumber is a test framework that supports BDD. Each step is implemented in its own action, making sure that steps are sequential and occur in the same request. The primary purpose of BDD frameworks is to support Behavior-Driven Development, where all technical (e.g., developers) and non-technical (e.g., business analysts) participants in a software project collaborate to define a common understanding of how the software should behave. This framework targets the Core Business layer in OutSystems proposed 4-Layer Canvas. Now we’ll implement the “I add the product to the cart” step of the When group.
