+This extension is a file intent handler and does the following during the test:

+1. Its background page first registers content hander.
+2. When content handler callback is invoked, opens tab.html page and passes
+   file url via hash ref.
+3. Tries to resolve target file url and reads its content.
+4. Send file content to file browser extension.
