function FileValidatorTest::testFileValidateImageResolution

This ensures the resolution of a specific file is within bounds. The image will be resized if it's too large.

File

core/modules/simpletest/tests/file.test, line 406

This provides SimpleTests for the core file handling functionality. These include FileValidateTest and FileSaveTest.

Class

FileValidatorTest

This will run tests against the file validation functions (file_validate_*).
