I think that if you put this file here, it will break other unit tests that
expect a certain number of extensions in this directory.

Even if not, it's a bit weird as this directory is used to test a specific
feature (it's badly named), and this test has nothing to do with that feature.

Please move this to test/data/extensions/extension_with_key/

Moved to chrome/test/data/extensions/override_component_extension/manifest.json

+  "name": "Bookmark Manager",

[Aaron Boodman, 2011/12/06 19:43:35]

Most of these keys are irrelevant to the test. You can remove everything except
the name, version, and key. Please make the name something descriptive, like
"Extension with key"

[SeRya, 2011/12/06 22:19:37]

Done.
