Prepending with the double dash is needed because the arguments would otherwise be sent to Composer itself, not the tool that Composer executes.

The same mechanism works for narrowing a run down further, or for bailing out early:

### Linting the feature files

`composer lint-gherkin` checks `features/` with
[gherkin-lint-plus](https://www.npmjs.com/package/gherkin-lint-plus), against the
`.gherkin-lintrc` ruleset shipped with this package. A project that needs
different rules can override it by committing its own `.gherkin-lintrc`.

The linter is a Node package, so it is run through `npx` and needs Node.js 20 or
later. Where `npx` is not available the check reports that it is skipping, rather
than failing a suite that is otherwise entirely PHP. Its version is pinned in
this package's `package.json`, which exists only to hold that pin.

### Controlling the amount of output

Two environment variables make the test tools less chatty. Both are unset by default, which leaves the output exactly as it has always been.

- `NO_COLOR` (the [no-color.org](https://no-color.org/) convention) stops the runners from forcing ANSI color codes on, and leaves the decision to each tool's own terminal detection. Set this when capturing output to a file or a pipe, where the escape sequences are noise.
- `WP_CLI_TEST_QUIET` switches the reporters to their most compact form: PHP_CodeSniffer reports one `file:line:col` line per violation with no progress ticker, PHPStan reports one `file:line:message` line per error with no progress bar and no result table. Behat's own output is already minimal, so it is unaffected.

`NO_COLOR` also covers the Gherkin linter, which colors its report unconditionally and has no plain output format of its own.

```bash
NO_COLOR=1 WP_CLI_TEST_QUIET=1 composer phpstan
```

This is worth setting permanently in environments that read the output back rather than display it, such as an AI coding agent's shell:

```bash
export NO_COLOR=1
export WP_CLI_TEST_QUIET=1
```

Validate WP_CLI_TEST_WP_VERSION_CACHE_TTL before using it.

If the value is non-numeric, Line 119 reports an integer-comparison error and then accepts the cache at any age. A typo such as WP_CLI_TEST_WP_VERSION_CACHE_TTL=foo can therefore prevent version metadata refreshes.

Reject invalid values before calling read_versions_cache, or fall back to 86400.

value; for invalid or unset input, fall back to 86400 so the integer comparison
at line 119 remains safe and cache expiration works correctly.

Set connection and total time limits for curl.

On a cache miss, this request can wait indefinitely for DNS, connection setup, or a response. The Behat runner then hangs instead of falling back to stale metadata or reporting the unavailable metadata.

Use --connect-timeout and --max-time.

Write the cache atomically.

Concurrent Behat runners can read this file after truncation and before printf completes. Lines 117-129 accept any nonempty cache file, so a reader can pass partial JSON to jq and fail version resolution.

Write to a temporary file in the cache directory, then replace WP_VERSIONS_CACHE_FILE with mv only after the write succeeds.
