Advanced continuous integration
In Chapter 4, Automated Testing, CI, and Release to Production, we covered a basic CircleCI pipeline leveraging default features. Beyond the basic automation of unit test execution, one of the other goals of CI is to enable a consistent and repeatable environment to build, test, and generate deployable artifacts of your application with every code push. Before pushing some code, a developer should have a reasonable expectation that their build will pass; therefore, creating a reliable CI environment that automates commands that developers can also run in their local machines is paramount. To achieve this goal, we will build a custom build pipeline that can run on any OS without configuration or any variation in behavior.
This section uses the lemon-mart repo. Ensure that your project has been properly configured by executing npm run docker:debug as described earlier in the chapter.
