Resolve #3488381 "Create unit test"

This Drupal kernel test is designed to verify the functionality of a method named getAsFileEntity within a php trait that extends AbstractFileBase. This method is part of the AI module and is responsible for creating and managing file entities in Drupal.

The test uses the KernelTestBase class, which sets up a minimal Drupal environment, allowing it to interact with core modules like 'file' without loading all of Drupal's features. It also installs necessary user and file modules required by the trait being tested.

Test Cases

1. testGetAsFileEntityWithValidPathAndFilename:

   • This test ensures that the getAsFileEntity method works correctly when provided with a valid path and filename.

2. testGetAsFileEntityWithEmptyPath:

   • This tests how the method handles an empty file path, which should default to 'public://'.

3. testGetAsFileEntityWithNonExistingDirectory:

   • This checks if the method behaves as expected when provided with a non-existing directory.

4. testGetAsFileEntityWithExistingFile:

   • This test verifies that the method correctly creates and returns an existing file entity with specified binary data and MIME type.

Common Assertions

For each test case, assertions are made to ensure:

• The returned object is an instance of Drupal\file\Entity\File.
• The file URI, MIME type, and filename match the expected values.

After testing, any created files are deleted from the filesystem using $this->fileSystem->delete($uri) to clean up after each test case.

Reusability

The method handleFileEntityAssertions is used to reduce code duplication. It encapsulates common assertions for different scenarios and can be called from multiple test cases with varying paths, demonstrating reusability of test logic in unit tests.

Overall, this test suite ensures that the getAsFileEntity method operates correctly under various conditions and interacts properly with Drupal's file entity system, providing comprehensive coverage of its functionality.
