 # generator.py
 
 The files under
 - /fetch/window/
 - /fetch/workers/
 - /fetch/serviceworker/
 - /fetch/serviceworker-proxied/
 are generated by the generator.
 Run
 $ python generate.py
 at this (/LayoutTests/http/tests/fetch/) directory to generate these files
 from templates script-tests/TEMPLATE*.html.
 
+There are two kinds of tests. One is regular tests placed on script-tests
+directory and another is "thorough" tests placed on script-tests/thorough
+directory. Each has its own template files and default option settings.
+Note: thorough tests were called as "fetch-access-control" tests. auth.js
+was called as fetch-access-control-auth.js, for example.

 # Running on window, workers, serviceworker, serviceworker-proxied
 
 As it is exposed to Window and Worker, most (if not all) of tests are expected
 to run on Window, DedicatedWorker and ServiceWorker.
 For each test (say X), we have
 - a script X.js in /fetch/script-tests,
 - /fetch/window/X.html Window test file,
 - /fetch/workers/X.html Worker test file, and
 - /fetch/serviceworker/X.html ServiceWorker test file.

 X.js is common to all options.
 The test switches by location.href at runtime.
 
 The options to be generated is listed in a line in X.js like:
 // OPTIONS: ,-other-https,-base-https-other-https
 (Three files for OPTIONS = (empty), -other-https, -base-https-other-https are
 generated)
 Default:
-  For fetch-access-control*: ,-other-https,-base-https-other-https
+  For thorough tests: ,-other-https,-base-https-other-https
   For others: ,-base-https-other-https

 # PRESUBMIT.py
 
 FIXME: currently PRESUBMIT.py is somehow outdated and thus disabled.
 
 PRESUBMIT.py checks the existence of the files.
 For each file in /fetch/script-tests, the
 corresponding html files must exist at the paths listed above.
