__construct(string $root, $class_loader)

Constructs a new test discovery.

Parameters

string $root

The app root.
$class_loader

The class loader. Normally Composer's ClassLoader, as included by the front controller, but may also be decorated; e.g., \Symfony\Component\ClassLoader\ApcClassLoader.

at line 74
array registerTestNamespaces()

Registers test namespaces of all extensions and core test classes.

Return Value

array

An associative array whose keys are PSR-4 namespace prefixes and whose values are directory names.

at line 148
array getTestClasses(string $extension = NULL, array $types = [])

Discovers all available tests in all extensions.

Remove singular grouping; retain list of groups in 'group' key.

Parameters

string $extension

(optional) The name of an extension to limit discovery to; e.g., 'node'.
array $types

An array of included test types.

Return Value

array

An array of tests keyed by the group name. If a test is annotated to belong to multiple groups, it will appear under all group keys it belongs to.

array findAllClassFiles(string $extension = NULL)

Discovers all class files in all available extensions.

Parameters

string $extension

(optional) The name of an extension to limit discovery to; e.g., 'node'.

Return Value

array

A classmap containing all discovered class files; i.e., a map of fully-qualified classnames to pathnames.

static array scanDirectory(string $namespace_prefix, string $path)

Scans a given directory for class files.

Limit to '*Test.php' files (~10% less files to reflect/introspect).

Parameters

string $namespace_prefix

The namespace prefix to use for discovered classes. Must contain a trailing namespace separator (backslash). For example: 'Drupal\node\Tests\'
string $path

The directory path to scan. For example: '/path/to/drupal/core/modules/node/tests/src'

Return Value

array

An associative array whose keys are fully-qualified class names and whose values are corresponding filesystem pathnames.

static array getTestInfo(string $classname, string $doc_comment = NULL)

Retrieves information about a test class for UI purposes.

Parameters

string $classname

The test classname.
string $doc_comment

(optional) The class PHPDoc comment. If not passed in reflection will be used but this is very expensive when parsing all the test classes.

Return Value

array

An associative array containing:

  • name: The test class name.
  • description: The test (PHPDoc) summary.
  • group: The test's first @group (parsed from PHPDoc annotations).
  • groups: All of the test's @group annotations, as an array (parsed from PHPDoc annotations).
  • requires: An associative array containing test requirements parsed from PHPDoc annotations:
    • module: List of Drupal module extension names the test depends on.

Exceptions

MissingGroupException

at line 391
static string parseTestClassSummary(string $doc_comment)

Parses the phpDoc summary line of a test class.

Parameters

string $doc_comment

Return Value

string

The parsed phpDoc summary line. An empty string is returned if no summary line can be parsed.

at line 427
static array parseTestClassAnnotations(ReflectionClass $class)

Parses annotations in the phpDoc of a test class.

Parameters

ReflectionClass $class

The reflected test class.

Return Value

array

An associative array that contains all annotations on the test class; typically including:

  • group: A list of @group values.
  • requires: An associative array of @requires values; e.g.:
    • module: A list of Drupal module dependencies that are required to exist.
