Continuous Integration

A sophisticated test suite only provides value if it is executed consistently. Relying on individual researchers to remember to run tests manually on their local machines guarantees that tests will eventually be forgotten, skipped, or ignored. Modern software engineering enforces quality entirely through automated Continuous Integration (CI) pipelines.

Using platforms tightly coupled to the version control system, the entire testing workflow is automated. Whenever a developer pushes a new commit to the repository or opens a pull request, the CI server instantly provisions a clean, isolated virtual machine. It installs the exact dependencies specified by the project, configures the environment, and executes the entire pytest suite from scratch.

If any individual test fails, or if the overall code coverage drops below a preconfigured acceptable threshold, the CI pipeline immediately halts and blocks the proposed code from being merged into the main branch. This automated mechanism creates an impenetrable barrier against regression. It guarantees that the main repository always contains a working, mathematically verified artifact, achieving the ultimate goal of operational continuity. The code ceases to be a localized experiment running on a single laptop; it becomes a resilient, peer-reviewed, and highly reliable scientific instrument.
