coverage

Overview ¶

Package coverage attributes a test to the features it covers, beyond the one its name already claims.

Attribution is by test name first, and that is deliberate: a test called TestSinkClickhouse_InsertsRows costs nothing to attribute and says what it covers to anyone reading it. One test per feature stays the goal.

Some tests genuinely cover several features at once. An end-to-end run reads a Kafka source, drives a handler, writes a sink and commits state -- naming it for one of those and calling the rest uncovered produces false gaps, and a gate that cries wolf gets ignored. Covers records the others.

Reach for it only when a test really does prove several features. If a feature needs a marker to be covered at all, it wants its own test.
