How to Stop Hating your Test Suite
summary
Promises a ready‑to‑fork Test Style Guide and then shows specific, actionable rules: break big objects (example four booleans => 2^4 = 16 test cases), prefer one public method and three dependencies per new object, split suites into one maximally realistic and one maximally isolated, and prefer given when then style (rspec‑given/MiniTest examples). Measures feedback in seconds (ties test duration to daily “thoughts”), warns of superlinear build slowdown, and recommends capping build time and eliminating redundant coverage.
