Adds two opt-in environment variables to the runner scripts, both unset by default so existing output is unchanged: * NO_COLOR (https://no-color.org/) stops the runners from forcing ANSI color codes on. parallel-lint and PHPUnit forced them unconditionally, which meant escape sequences in every captured log. * WP_CLI_TEST_QUIET switches the reporters to their most compact form: PHP_CodeSniffer to one line per violation with no progress ticker, PHPStan to one line per error with no progress bar and no result table, and Behat to omitting step definition snippets. Also documents narrowing a Behat run to a single scenario, --stop-on-failure and composer behat-rerun.

Every `composer behat` invocation resolved WP_VERSION over the network: one request to api.wordpress.org for `latest`, and a second one to the wp-versions artifact when the version has no patch number. That cost applies equally to a full suite run and to re-running one scenario for the fifth time while iterating on a fix. The answers now go into a cache in the system temp directory with a configurable lifetime, defaulting to a day. Two side effects worth noting: * A run without connectivity falls back to the last known answer rather than continuing with an empty WP_VERSION, which silently disabled the filtering of version-specific tags. * When there is nothing to fall back to, that case is now reported instead of being silent.

The feature files are linted on every pull request, but the check lives entirely in the reusable CI workflow and its ruleset lives in wp-cli/.github, so contributors cannot run it locally at all. A green `composer test` is therefore not a green build, and the way to find out is to push. Moves the check to where the other suites are: `.gherkin-lintrc` ships with this package as the shared default, a project can override it by committing its own, and `composer lint-gherkin` runs it. CI can then call the same script rather than reimplementing the invocation. Uses gherkin-lint-plus, pinned, and overridable through WP_CLI_TEST_GHERKIN_LINT_VERSION. Being a Node package, it is invoked through npx and skips with a message where npx is absent, rather than failing a suite that is otherwise entirely PHP. The linter colors its report unconditionally and offers no plain output format, so NO_COLOR strips the escape sequences from its output.

Drops the WP_CLI_TEST_GHERKIN_LINT_VERSION override, which was configuration nobody asked for, and puts the pinned version somewhere a dependency bot can see it. A version string inside a shell script is invisible to Dependabot; a devDependency in package.json is not. The package.json exists only to hold that pin: it is private, has no scripts, and nothing runs `npm install` against it. The runner reads the version out of it and fails loudly if it is missing, rather than quietly falling through to whatever the latest release happens to be. Note that picking these updates up needs an npm entry in the dependabot.yml that wp-cli/.github syncs out.

Two points from review: * The wp-versions artifact already marks the current release with a "latest" status, so the separate request to api.wordpress.org was redundant. Both the "latest" and the X.Y resolution now come out of that one file, which means one cached artifact and at most one network request per run instead of two. * Behat's step definition snippets are not only printed when writing new step definitions; they are also how a typo in an existing step surfaces. That makes them a diagnostic rather than noise, and they only appear when something is already wrong, so suppressing them under WP_CLI_TEST_QUIET saved nothing in the passing case and cost information in the failing one. Dropped, which leaves WP_CLI_TEST_QUIET with no effect on Behat. Also adds lint-gherkin to the setup instructions, which listed the scripts a consuming package should wire up but not the new one.

Three points from review, all on the caching added to the Behat runner:
* A non-numeric WP_CLI_TEST_WP_VERSION_CACHE_TTL made `[ "${ttl}" -ge 0 ]`
fail rather than evaluate, which skipped the age check entirely and left the
cached copy valid forever. A typo therefore turned the cache into one that
never refreshes. Validated up front now, with a warning and the default TTL.
* The fetch was unbounded, so an unreachable or unresponsive host held up the
whole run instead of falling back to the cached copy. Bounded with
--connect-timeout and --max-time, after which the existing stale-cache path
takes over.
* The cache was written by truncating the target in place, so a concurrent
runner could read it between the truncation and the end of the write and hand
partial JSON to jq. It now goes to a temporary file in the same directory and
is moved into place, which is atomic. The move keeps the file readable to
others, as the shared cache directory needs and the old redirect did.

Conflict in bin/run-phpstan-tests: main split the runner into two numbered phases and collects an exit code across them, while this branch added the NO_COLOR and WP_CLI_TEST_QUIET flags to the analyse call. Kept both, so the first phase still takes the optional flags and now also feeds EXIT_CODE. The second phase, which runs PHPStan over the PHP blocks in feature files, needs nothing here: it already passes --no-progress and reports through its own formatter, which emits no ANSI sequences.
The fetch path checked that a response was a non-empty object before caching it, but the read path only checked that the file was not empty. An unparsable cache was therefore handed straight to jq, which meant a run inside the TTL made no request at all, leaked a jq parse error, and continued with an empty WP_VERSION -- silently dropping the @require-wp-* filtering that the cache was added to protect. Every subsequent run repeated it until the entry aged out. Both paths now share one check, so an unusable cache counts as a miss and the network gets a chance to replace it. The TTL validation moves into get_wp_versions along with it, so that a typo is only reported when a lookup is actually going to happen rather than on every run, and its warning joins the other one on STDERR.

Dropping --colors left php-parallel-lint at its default autodetection, which only asks whether STDOUT is a terminal -- php-console-color has no NO_COLOR handling of its own. So NO_COLOR=1 composer lint still printed escape sequences interactively, while the other three runners disabled color outright. --no-colors has been available since v1.3, so this is the same one-flag treatment the PHPUnit, PHPStan and Behat runners already get. The README described the old behavior, which contradicted the no-color.org convention it cites; it now says what the runners do. The two bullets also pick up the list marker used everywhere else in the file. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GjJi6F76YZBt7cRrvXS6s6
WP_CLI_TEST_QUIET is meant to be exported once and left set, so it has to stay out of the way of a report asked for on the command line. It did not: PHPCS gives no way for a later --report to replace an earlier one, so composer phpcs -- --report=summary printed both reports on 3.x and only the injected emacs one on 4.x. The compact report is now skipped when the caller names a report of their own. -q stays either way, since a later -v does override it.

The temporary file holding the linter's STDERR was only removed on the normal path, so a Ctrl-C during a lint left it behind.

Conflict in bin/run-phpcs-tests: #340 restructured it into a standard run plus a run over the PHP blocks in feature files, the same shape the PHPStan runner already has. Resolved by taking that structure and re-applying WP_CLI_TEST_QUIET to the standard run only, which is where this branch had it and which matches how the PHPStan runner treats its own second section. The block check keeps the default report on purpose: its findings are rewritten back onto the feature files with a sed over the "FILE:" headers, which a compact report would not produce.

Two findings from the review of the merge commit: WP_CLI_TEST_QUIET was described as switching "the reporters" to their most compact form, which overpromised. It reaches the analysis of the PHP files; the checks over the PHP blocks extracted from feature files keep their own reports, because both rewrite their findings back onto the feature file a block came from and a compact report is not what those rewrites are written against. The README now says so. A signal handler resumes where it left off rather than ending the script, so after an interrupt the Gherkin runner went on to read its report back out of the file the handler had just removed. The cleanup on EXIT stays; HUP, INT and TERM now clean up and stop, with the 128+n status a shell reports for a death by signal.

Brings in the README regeneration from #361, which adds the section #340 had only written into .readme-partials/USING.md. It merged cleanly with this branch's own README additions. Checked afterwards that every section the partial defines still matches its generated counterpart byte for byte, so the next regeneration stays a no-op.

Three independent changes coming out of the discussion in wp-cli/wp-cli#6161 about what it costs an AI agent — or anyone iterating in a terminal — to work in a WP-CLI repository. Happy to split them into separate pull requests if that reads better.
Pairs with wp-cli/.github#285, which rewrites the
composer testguidance inAGENTS.mdand points the CI Gherkin job atcomposer lint-gherkin.1. Quieter output, opt-in
Two environment variables, both unset by default, so nothing changes for existing users or for CI:
NO_COLOR(no-color.org) stops the runners from forcing ANSI color on.run-linter-testspassed--colorsandrun-php-unit-testspassed--color=alwaysunconditionally, so every captured log carried escape sequences whether or not anything was going to render them. Where a project's own config can turn color back on —phpunit.xmlwithcolors="true"— the flag is set to an explicitneverrather than omitted.WP_CLI_TEST_QUIETswitches the reporters to their most compact form:-q --report=emacs, onefile:line:colline per violation, no progress ticker--no-progress --error-format=raw, onefile:line:messageline per error, no redrawing progress bar and no box-drawing result tableBehat is deliberately untouched: its
progressoutput is already minimal, and its step definition snippets are how a typo in an existing step surfaces, so they are a diagnostic rather than noise.Also documents, in the README, things the runners already supported but nobody had written down: narrowing a Behat run to a single scenario with
features/x.feature:12,--tags=,--stop-on-failure, andcomposer behat-rerun.2. Cache the WP_VERSION lookup
run-behat-testsresolvedWP_VERSIONover the network on every single invocation, whether you were running the full suite or re-running one scenario for the fifth time while iterating on a fix.It also made two separate requests for what is one question. The
wp-versionsartifact already carries a status per release with the current one markedlatest, so the extra call toapi.wordpress.orgwas redundant. Both thelatestresolution and theX.Y→ latest-patch resolution now come out of that single file.It is cached under the system temp directory, following the
wp-cli-test-*naming theFeatureContextcore download cache already uses. Lifetime defaults to a day and is configurable throughWP_CLI_TEST_WP_VERSION_CACHE_TTL, where0fetches every run. Net effect: at most one request per run, and none at all on a warm cache.Two behavior changes fall out of it, both of which look like improvements but are worth calling out explicitly:
WP_VERSION, which silently disabled filtering of the@require-wp-*tags.WP_VERSION=X.Y.0still normalizes toX.Yand stops there, rather than resolving on to the newest patch — that spelling asks for the initial release specifically.3. Bring the Gherkin linting into the test suite
The feature files are linted on every pull request, but the check exists only inside the reusable CI workflow and its ruleset lives in
wp-cli/.github. Contributors cannot run it locally at all — not "it is inconvenient", but there is no config file in the repository to run it against. Socomposer testpassing does not mean the build passes, and the way to find out is to push.This moves it next to the other suites:
.gherkin-lintrcships with this package as the shared default ruleset, carried over unchanged fromwp-cli/.github. A project that needs different rules overrides it by committing its own.composer lint-gherkinruns it, and it joinscomposer testand the setup instructions.Uses gherkin-lint-plus. It is a Node package, so it runs through
npxand needs Node.js 20 or later; wherenpxis absent it reports that it is skipping rather than failing a suite that is otherwise entirely PHP. That is a deliberate trade — a hard failure would breakcomposer testfor every PHP-only contributor across ~40 repositories — and CI, where Node is always present, still enforces it.The version is pinned in a
package.jsonthat exists for no other purpose: it is private, has no scripts, and nothing runsnpm installagainst it. The pin lives there rather than in the shell script because a version string in a shell script is invisible to Dependabot. Picking the updates up needs the npm entry added in wp-cli/.github#285.One wrinkle worth recording: the linter writes its report to STDERR and colors it unconditionally, honoring neither
NO_COLORnor the absence of a terminal, andstylishis its only output format. So the runner strips the escape sequences from that stream itself whenNO_COLORis set, preserving STDOUT and the exit code.Testing
The Gherkin linting is verified end to end, since Node was available where I was working:
wp-cli/wp-cli's thirty-five pass cleanly under the ported ruleset, so adopting this does not start with a wall of pre-existing violations.file-name,no-unnamed-scenarios,indentationanduse-andare all caught, exit code 1, whileno-trailing-spacescorrectly stays quiet because the shared config disables it. The fork reads the existing ruleset the same waygherkin-lintdid,indentationoption keys included.NO_COLOR=1output is stripped of escape sequences with the exit code preserved; the default run keeps its colors; a clean tree prints nothing and exits 0; an explicit path argument overrides thefeaturesdefault; a package with nofeaturesdirectory skips and exits 0; apackage.jsonwith the pin removed fails with a message rather than silently installing the latest release.The version resolution was exercised against a stubbed
curland the real artifact: cold cache, warm cache withcurlremoved fromPATHentirely (zero requests), stale entry with the network down, a malformed response,latest→7.0.4,6.8→6.8.8,6.9.0→6.9,7.0.0→7.0, andtrunkand exact versions passing through untouched. All the shell is syntax-checked andcomposer validatepasses.What I could not do is run the PHP suites.
composer installdoes not complete in the environment I am working in —phpstan/phpstanis dist-only and its dist URL is onapi.github.com, which is blocked here. So the flags in the first commit (--report=emacs,--error-format=raw,--color=never) are unverified by execution and rest on the documented CLI surface of each tool. That is the part of this pull request that most needs CI, or a second pair of eyes.Refs wp-cli/wp-cli#6161
