- * Description of the Tests for
- *  - Bug 418354 - Call Mixed content blocking on redirects
- *
- * Single redirect script tests
- * 1. Load a script over https inside an https page
- *    - the server responds with a 302 redirect to a >> HTTP << script
- *    - the doorhanger should appear!
- *
- * 2. Load a script over https inside an http page
- *    - the server responds with a 302 redirect to a >> HTTP << script
- *    - the doorhanger should not appear!
- *
- * Single redirect image tests
- * 3. Load an image over https inside an https page
- *    - the server responds with a 302 redirect to a >> HTTP << image
- *    - the image should not load
- *
- * 4. Load an image over https inside an http page
- *    - the server responds with a 302 redirect to a >> HTTP << image
- *    - the image should load and get cached
- *
- * Single redirect cached image tests
- * 5. Using offline mode to ensure we hit the cache, load a cached image over
- *    https inside an http page
- *    - the server would have responded with a 302 redirect to a >> HTTP <<
- *      image, but instead we try to use the cached image.
- *    - the image should load

- * 6. Using offline mode to ensure we hit the cache, load a cached image over
- *    https inside an https page
- *    - the server would have responded with a 302 redirect to a >> HTTP <<
- *      image, but instead we try to use the cached image.
- *    - the image should not load
- *
- * Double redirect image test
- * 7. Load an image over https inside an http page
- *    - the server responds with a 302 redirect to a >> HTTP << server
- *    - the HTTP server responds with a 302 redirect to a >> HTTPS << image
- *    - the image should load and get cached
- *
- * Double redirect cached image tests
- * 8. Using offline mode to ensure we hit the cache, load a cached image over

- * not enabled on that platform (platform shim; the application is kept running
- * although there are no windows left)

- * BrowserTryToCloseWindow() as opposed to close(). The former will make

-/**
- * This is where most of the action is happening. This function takes
- * an Array of "test scenario" Objects and runs them. For each scenario, a
- * window is opened, put into some state, and then a new state is
- * loaded into that window. We then check to make sure that the
- * right things have happened in that window wrt remoteness flips.
- *
- * The schema for a testing scenario Object is as follows:
- *
- * initialRemoteness:
- *   an Array that represents the starting window. Each bool
- *   in the Array represents the window tabs in order. A "true"
- *   indicates that that tab should be remote. "false" if the tab
- *   should be non-remote.
- *
- * initialSelectedTab:
- *   The 1-based index of the tab that we want to select for the
- *   restored window. This is 1-based to avoid confusion with the
- *   selectedTab property described down below, though you probably
- *   want to set this to be greater than 0, since the initial window
- *   needs to have a defined initial selected tab. Because of this,
- *   the test will throw if initialSelectedTab is 0.
- *
- * stateToRestore:
- *   A JS Object for the state to send down to the window.
- *
- * selectedTab:
- *   The 1-based index of the tab that we want to select for the
- *   restored window. Leave this at 0 if you don't want to change
- *   the selection from the initial window state.
- *
- * expectedFlips:
- *   an Array that represents the window that we end up with after
- *   restoring state. Each bool in the Array represents the window tabs,
- *   in order. A "true" indicates that the tab should have flipped
- *   its remoteness once. "false" indicates that the tab should never
- *   have flipped remoteness. Note that any tab that flips its remoteness
- *   more than once will cause a test failure.
- *
- * expectedRemoteness:
- *   an Array that represents the window that we end up with after
- *   restoring state. Each bool in the Array represents the window
- *   tabs in order. A "true" indicates that the tab be remote, and
- *   a "false" indicates that the tab should be "non-remote". We
- *   need this Array in order to test pinned tabs which will also
- *   be loaded by default, and therefore should end up remote.
