Now let's execute the test case. This involves two steps, as we are using the wire protocol. Let's first launch the test case executable in background mode and then Cucumber, as follows:
cmake --build build
build/HelloBDD/HelloBDDSteps > /dev/null &
cucumber HelloBDD
Redirecting to /dev/null isn't really mandatory. The main purpose of redirecting to a null device is to avoid distractions from the print statement that an application may spit in the terminal output. Hence, it is a personal preference. In case you prefer to see the debug or general print statements from your application, feel free to issue the command without redirection:
build/HelloBDD/HelloBDDSteps &
The following screenshot demonstrates the build and test execution procedure:
Congrats! our very first cucumber-cpp test case has passed. Each scenario represents a test case and the test case includes three steps; as all the steps passed, the scenario is reported as passed.
