protected function TestFileCreationTrait::getTestFiles in Drupal 9

Same name and namespace in other branches

1. 8 core/tests/Drupal/Tests/TestFileCreationTrait.php \Drupal\Tests\TestFileCreationTrait::getTestFiles()

Gets a list of files that can be used in tests.

The first time this method is called, it will call $this->generateFile() to generate binary and ASCII text files in the public:// directory. It will also copy all files in core/tests/fixtures/files to public://. These contain image, SQL, PHP, JavaScript, and HTML files.

All filenames are prefixed with their type and have appropriate extensions:

• text-*.txt
• binary-*.txt
• html-*.html and html-*.txt
• image-*.png, image-*.jpg, and image-*.gif
• javascript-*.txt and javascript-*.script
• php-*.txt and php-*.php
• sql-*.txt and sql-*.sql

Any subsequent calls will not generate any new files, or copy the files over again. However, if a test class adds a new file to public:// that is prefixed with one of the above types, it will get returned as well, even on subsequent calls.

Parameters

$type: File type, possible values: 'binary', 'html', 'image', 'javascript', 'php', 'sql', 'text'.

$size: (optional) File size in bytes to match. Defaults to NULL, which will not filter the returned list by size.

Return value

array[] List of files in public:// that match the filter(s).
