Writing our first Cucumber test case

Let's write our very first Cucumber test case! As this is our first exercise, I would like to keep it short and simple. First, let's create the folder structure for our HelloBDD project.

To create the Cucumber project folder structure, we can use the cucumber utility, as follows:

cucumber --init

This will ensure that the features and steps_definitions folders are created as per Cucumber best practices:

Once the basic folder structure is created, let's manually create the rest of the files:

mkdir src
cd HelloBDD
touch CMakeLists.txt
touch features/hello.feature
touch features/step_definitions/cucumber.wire
touch features/step_definitions/HelloBDDSteps.cpp
touch src/Hello.h
touch src/Hello.cpp

Once the folder structure and empty files are created, the project folder structure should look like the following screenshot:

It's time to start applying our Gherkin knowledge in action; hence, let's first start with the feature file:

# language: en

Feature: Application...
