PR Checklist

The PR title follows our guidelines: https://github.com/NativeScript/NativeScript/blob/master/tools/notes/CONTRIBUTING.md#commit-messages.
There is an issue for the bug/feature this PR is for. To avoid wasting your time, it's best to open a suggestion issue first and wait for approval before working on it.
You have signed the CLA.
All existing tests are passing: https://github.com/NativeScript/nativescript-cli/blob/master/CONTRIBUTING.md#contribute-to-the-code-base
Tests for the changes are included.

What is the current behavior?

--watch defaults to true globally (lib/options.ts), so ns test <platform> resolves watch mode even when the flag was never passed:

In Vitest projects, ns test ios --device <id> prints '--watch' is not supported for on-device Vitest runs yet; running once. on every run — including CI runs where watch can never work.
In Karma projects, watch mode means singleRun is never set (lib/services/test-execution-service.ts), so ns test in CI keeps the process alive after the tests finish instead of exiting.

What is the new behavior?

The ns test commands declare their own --watch default: off when a CI environment is detected (the existing isCIEnvironment() check — CI/JENKINS_HOME), on otherwise. This uses the same command-specific dashedOptions mechanism that already overrides the --hmr default for ns test.

CI: ns test ios --device <id> runs once and exits; no spurious --watch warning for Vitest projects, and singleRun: true for Karma projects.
Local interactive use is unchanged: watch stays on by default.
Explicit --watch / --no-watch still take precedence over the default.
isCIEnvironment() in lib/common/helpers.ts is now exported so commands can use it.

No issue was filed for this; happy to open one if preferred.

Summary by CodeRabbit

New Features
- Android and iOS test commands now rerun tests when project files change by default outside CI. Use --no-watch to run tests once; watch mode defaults off when CI or JENKINS_HOME is set.
Bug Fixes
- On-device test runs now show the watch-mode warning only when --watch is explicitly enabled.

Sorry, something went wrong.

          fix(test): default --watch to off for ns test in CI environments

28a484b

--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.

📝 Walkthrough

Test commands now default watch mode on outside CI and off in CI. The --watch and --no-watch flags override that default. The iOS Vitest warning now appears only when watch is enabled and an explicit --watch argument is present. Tests and man pages cover these behaviors.

Changes: Test Watch Defaults

Layer / File(s)	Summary
Set and verify watch defaults `lib/commands/test.ts`, `lib/common/helpers.ts`, `test/commands/test.ts`, `docs/man_pages/project/testing/*`	The test command sets the `watch` default based on the CI environment. Tests check defaults and explicit flags. The Android and iOS man pages document the default and overrides.
Align the iOS Vitest warning with explicit flags `lib/services/vitest-execution-service.ts`, `test/services/vitest-execution-service.ts`	The warning now depends on `process.argv` containing an explicit `--watch` or `--watch=...` argument while watch is enabled. Tests cover explicit watch arguments, default watch behavior, and disabled watch.

          fix(test): only warn about --watch for Vitest runs when passed explic…

6c0ef40

…itly

Watch mode defaults to on outside CI, so checking $options.watch printed
the unsupported-watch warning on every local Vitest run. Also document
JENKINS_HOME alongside CI in the --watch man page entries.

          fix(test): base the Vitest --watch warning on the parsed watch value

Handle --watch=true and --watch false/--watch=false, not only a bare --watch.
