The Hell of Automated Tests
summary
Practical advice for building reliable, fast automated test suites used at companies like Google and Netflix: aim for 5–15 minute feedback by splitting suites into quick and nightly runs, parallelizing tests, and running selective tests. Concrete techniques covered include the functional core/imperative shell pattern, using mocks/fakes and test containers (including containerized or fake databases), temporary-file tests in Python demos, and removing flaky or obsolete tests while treating coverage, snapshots, and fuzzing as pragmatic tools.
