Configuring the pipeline for testing

Our testing pipeline will consist of two jobs that should do the following:

• Run all code checks such as linting, type checking, unit and integration testing, and so on
• Build the application and run end-to-end tests

Code checks job

The code checks job should work as shown in the following diagram:

Figure 9.2 – Code checks job overview

As we can see, the job should be straightforward:

1. First, we need to provide environment variables to the application.
2. Then, we need to install the dependencies.
3. Next, we must run unit and integration tests.
4. Then, we must run linting.
5. After, we must check the code format.
6. Finally, we must run type checking.

Within jobs, let’s add the job that runs these tasks:

jobs:
  code-checks:
    name: Code Checks
    runs-on: ubuntu-latest
