Stop Writing Tests!
summary
Argues to write fewer hand-crafted examples and automate the hard choices by generating and checking properties; shows using pip install hypothesis to write property-based tests, a Hypothesis ghostwriter that inspects code and emits tests, and a persistent Hypothesis fuzzer that runs tests under coverage. Demonstrates real results: fuzzer finds five or six bugs overnight that previous week-long runs missed, and ghostwriter plus pytest uncovers encoding and round‑trip counterexamples in live demos.
