TestRunner

Runs a package's phpunit suite and reports the result as data.

class MMO\core\TestRunner extends MMO\core\classes\aModule

Namespace: MMO\core
Extends: aModule

Any installed package is runnable: a package declares where its phpunit configuration is with the `tests` key of its `mmo.json` ([`PackageManifest::$tests`](https://mcp.mmoframework.fr/documentation/mmo.core/php/helpers/PackageManifest.md#packagemanifest-tests), `phpunit.xml` by default), and everything else follows from that one file -- which suites exist, which bootstrap to load, what to include. Nothing about a particular library is hard-coded here. ### What it actually runs phpunit itself, as a subprocess, with its machine-readable log turned on: ``` phpunit -c <the package's phpunit.xml> --log-junit <a temp file> --cache-directory <a temp dir> --do-not-cache-result --no-coverage --colors=never [--testsuite <name>] ``` The cache directory and the log are forced into [`$cacheFolder`](https://mcp.mmoframework.fr/documentation/mmo.core/php/TestRunner.md#testrunner-cachefolder) rather than left to the configuration: a suite run from the web server would otherwise try to write `.phpunit.cache` into the package folder, which is normally not writable by that user -- and a test run that fails for that reason looks exactly like a test run that failed. The JUnit log is the result; the console output is kept as well, because it is the only thing left to read when phpunit fails *before* running anything (a broken configuration, a missing bootstrap, no suite at all). ### It is a development tool Running a test suite executes the package's own code, with whatever side effects its tests have. [`$enabled`](https://mcp.mmoframework.fr/documentation/mmo.core/php/TestRunner.md#testrunner-enabled) is therefore off outside dev mode, and [`TestController`](https://mcp.mmoframework.fr/documentation/mmo.core/php/controllers/TestController.md#testcontroller) refuses every request when it is.

$result = \MMO\core\TestRunner::Shared()->run('mmo.core'); echo $result['tests'], ' tests, ', $result['failures'], " failures\n";

Properties6

binaries

array $binaries = ['{root}/vendor/bin/phpunit', '{root}/../vendor/bin/phpunit']

Type: array

binary

?string $binary = null

Type: null | string

cacheFolder

?string $cacheFolder = null

Type: null | string

The default is null on purpose: a shared folder under `{tmp}` is created by whoever runs first and is then owned by them, so the next run -- from the web server, from a cron, from another developer -- finds a directory it cannot write into, and every suite fails for a reason that has nothing to do with the tests. Set it only when the cache is worth keeping and the permissions are under control.

enabled

bool $enabled = true

Type: bool

maxOutputBytes

int $maxOutputBytes = 262144

Type: int

timeout

float $timeout = 300.0

Type: float

Methods10

buildCommand($config, $log, $cache, $suite)

TestRunner.php:253

Build the phpunit command line, every token escaped.

protected function buildCommand(string $config, string $log, string $cache, ?string $suite = null): string

$config	string	the package's phpunit.xml
$log	string	where the JUnit log is written
$cache	string	the cache directory phpunit is forced to use
$suite = null	null \| string
returns	string

collectProblems($suite, $suiteName, $problems)

TestRunner.php:328

Walk a suite's tree and collect every test case that did not pass.

protected function collectProblems(SimpleXMLElement $suite, string $suiteName, array &$problems): void

$suite	SimpleXMLElement
$suiteName	string	the top-level suite everything below belongs to
$problems	array
returns	void

DefaultConfig()

staticTestRunner.php:67

static function DefaultConfig(): array

returns

array

emptyResult()

TestRunner.php:350

protected function emptyResult(): array

returns

array

a result with nothing in it -- what a run that never got to execute a test reports.

getBinary()

TestRunner.php:132

function getBinary(): string

returns string the phpunit executable, looked up once ($binaries, then $PATH).

getLibraries()

TestRunner.php:80

Every installed package that ships a test suite.

function getLibraries(): array

returns

array

string, version: string, namespace: string, config: string, folder: string, suites: array<string>}> keyed by package name, in natural order

array_keys(\MMO\core\TestRunner::Shared()->getLibraries());// ['mmo.admin', 'mmo.client', ...]

getSuites($config)

TestRunner.php:111

The test suites a phpunit configuration declares, so one can be run on its own.

function getSuites(string $config): array

$config	string	the phpunit.xml filename
returns	array	the suite names, empty when the file declares none (or cannot be read)

parse($xml)

TestRunner.php:283

Turn phpunit's JUnit log into the result this module reports.

function parse(string $xml): array

JUnit nests a `<testsuite>` per suite, per class and per data provider, which is more structure than a report needs: this keeps the **top level** suites as the summary rows, and flattens every failing or erroring `<testcase>` into one flat list of problems -- what a reader wants is "what broke", not a tree.

$xml	string	the log's content
returns	array

run($library, $suite)

TestRunner.php:158

Run one package's test suite.

function run(string $library, ?string $suite = null): array

$library	string	the package name (`mmo.core`)
$suite = null	null \| string	one suite of its configuration, null for all of them
returns	array	{library, suite, config, command, ok, timedOut, exitCode, duration, tests, assertions, errors, failures, skipped, suites: [{name, tests, ...}], problems: [{suite, test, type, kind, message, file, line}], output}
throws		when the package is not installed, or ships no test suite
throws		when running tests is disabled

runAll()

TestRunner.php:228

Run every package that ships a test suite.

function runAll(): array

returns

array

{libraries: [name => result], tests, assertions, failures, errors, skipped, duration, ok}

$all = \MMO\core\TestRunner::Shared()->runAll(); echo $all['ok']? 'green' : 'red';

	Properties	Declared by	Description
	`verbosity`	aModule

Methods	Declared by	Description
`alert($message, $context)`	aModule	Action must be taken immediately.
`backtraces($message, $context)`	aModule	Force-log a message at INFO level together with a full stack trace/memory snapshot (`iLogLevel::BACKTRACE`), bypassing the verbosity mask entirely (any non-zero verbosity is enough to trigger it).
`Configure($config)`	aModule	Merge $config into this module's configuration in the shared `Configuration`.
`critical($message, $context)`	aModule	Critical conditions. No-op if CRITICAL is currently filtered out by the verbosity mask.
`debug($message, $context)`	aModule	Detailed debug information.
`debugName()`	aModule	Human-readable identifier used as the default `{origin}` in this instance's log messages.
`emergency($message, $context)`	aModule	System is unusable. No-op if EMERGENCY is currently filtered out by the verbosity mask.
`error($message, $context)`	aModule	Runtime errors that do not require immediate action but should typically be logged and monitored.
`getVerbosity()`	aModule
`info($message, $context)`	aModule	Interesting events. No-op if INFO is currently filtered out by the verbosity mask.
`Instantiate($config)`	aModule	(Re)create the shared instance immediately, configured with $config merged into the class's existing config.
`IsShared()`	aModule
`log($level, $message, $context)`	aModule	Logs with an arbitrary level.
`notice($message, $context)`	aModule	Normal but significant events.
`offsetExists($key)`	aModule	\ArrayAccess::offsetExists -- tells whether $key is a declared property at all, regardless of whether it is currently readable/writable through array access.
`offsetGet($key)`	aModule	\ArrayAccess::offsetGet -- reads a property directly, unless it has a `#[Serialize(serialize: 'methodName')]` attribute, in which case that zero-argument method is called instead (e.g.
`offsetSet($key, $value)`	aModule	\ArrayAccess::offsetSet -- sets a property directly, unless it has a `#[Serialize(unserialize: 'methodName')]` attribute, in which case that method is called with $value instead (e.g.
`offsetUnset($key)`	aModule	\ArrayAccess::offsetUnset -- equivalent to `$module[$key] = null`.
`serialize($path, $serializer)`	aModule	\MMO\core\interfaces\iSerializable::serialize -- exports every property (via
`setVerbosity($verb)`	aModule	Set the current verbosity mask, replacing whatever it was before.
`Shared()`	aModule	Get the shared instance, creating (and configuring) it on first call.
`testVerbosity($level)`	aModule	Test whether a given level (or set of levels) is currently enabled by this instance's verbosity mask.
`traitUnshare($serialize)`	aModule	Remove the shared instance, so the next `Shared()` call creates a fresh one.
`unserialize($data, $path, $instances)`	aModule	\MMO\core\interfaces\iSerializable::unserialize -- merges $data onto `DefaultConfig`, runs it through the (possibly overridden) constructor, then applies each resulting value to its property (via
`Unshare($serialize)`	aModule	Like `tSingleton::Unshare`, but also disconnects this module's instance from every event it was listening to (via `Event::DisconnectListeners`) before dropping it.
`warning($message, $context)`	aModule	Exceptional occurrences that are not errors.
`__construct($config)`	aModule	protected constructor, so it is not possible to do `new Module(...)` called by the serialization process just before being injected with data.
