Implementing the new frameworks

The implementation process guides us further on how frameworks in JavaScript can be created. In this implementation process, we’ll see the different entry points of a test runner combined with distinguishable features. This section roughly follows the diagram in Figure 6.2, where we outlined the framework design. Now that we know our features and have a rough idea of the project’s architecture, let’s broadly outline the steps of the internal implementation of this project, as follows:

1. Determine how the designed test suite configuration can be implemented within the Node.js environment.
2. Create internal packages to execute the test suites in different environments.
3. Implement the infrastructure for real web browser-mode testing.
4. Collect results from the test runner and output them to the user.

Following steps 1 to 4, we begin our implementation by examining how our tests are structured and executed. In the...
