// This file tests the packaged app service - nsIPackagedAppService
// NOTE: The order in which tests are run is important
//       If you need to add more tests, it's best to define them at the end
//       of the file and to add them at the end of run_test
//
// ----------------------------------------------------------------------------
//
// test_bad_args
//     - checks that calls to nsIPackagedAppService::GetResource do not accept a null argument
// test_callback_gets_called
//     - checks the regular use case -> requesting a resource should asynchronously return an entry
// test_same_content
//     - makes another request for the same file, and checks that the same content is returned
// test_request_number
//     - this test does not make a request, but checks that the package has only
//       been requested once. The entry returned by the call to getResource in
//       test_same_content should be returned from the cache.
//
// test_package_does_not_exist
//     - checks that requesting a file from a <package that does not exist>
//       calls the listener with an error code
// test_file_does_not_exist
//     - checks that requesting a <subresource that doesn't exist> inside a
//       package calls the listener with an error code
//
// test_bad_package
//    - tests that a package with missing headers for some of the files
//      will still return files that are correct
// test_bad_package_404
//    - tests that a request for a missing subresource doesn't hang if
//      if the last file in the package is missing some headers
//
// test_worse_package
//    - tests that a request for a missing/existing resource doesn't
//      break the service and the async verifier.
