fix(test): default --watch to off for ns test in CI environments - #6171
aleclarson wants to merge 1 commit into
Conversation
--watch defaults to true globally, so `ns test <platform>` always resolved watch mode even when the flag was never passed. For Vitest projects this printed a spurious "'--watch' is not supported" warning on every run, and for Karma projects it kept the process alive in CI instead of exiting after a single run. The test commands now declare their own --watch default, disabled when a CI environment is detected (CI/JENKINS_HOME). Explicit --watch and --no-watch still take precedence, and local behavior is unchanged.

A rabbit watches tests begin,
Outside CI, they run again.
In CI, watch rests its ears,--no-watch stops repeat runs here.
The docs now tell the flags with care,
And carrots mark the passing pair.

Document both CI signals for the watch default. The command disables watch when either CI or JENKINS_HOME is set. Each description names only CI, so it gives the wrong default for Jenkins environments that set only JENKINS_HOME.
