module `ActiveSupport::Testing::FileFixtures`

Adds simple access to sample files called file fixtures. File fixtures are normal files stored in ActiveSupport::TestCase.file_fixture_path.

File fixtures are represented as Pathname objects. This makes it easy to extract specific information:

file_fixture("example.txt").read # get the file's content
file_fixture("example.mp3").size # get the file size

Public instance methods

`file_fixture(fixture_name)`

Permalink

Returns a Pathname to the fixture file named fixture_name.

Raises ArgumentError if fixture_name can’t be found.
