// Tests that ChromePermissionMessageProvider provides not only correct, but
// meaningful permission messages that coalesce correctly where appropriate.
// There are 3 types of permission messages that need to be tested:
//  1. The combined list of active permissions, displayed at install time (or
//     when the app has been disabled automatically and needs to be re-enabled)
//  2. The split list of active permissions, displayed in the App Info dialog,
//     where the optional permissions are individually revokable
//  3. The list of requested optional permissions, displayed in a prompt to the
//     user when the app requests these during runtime
// Some of these tests are prefixed AntiTest_, since they demonstrate existing
// problematic functionality. These tests are prefixed with AntiTest_ and will
// be changed as the correct behaviour is implemented. TODOs in the test explain
// the currently problematic behaviour.

// If an app has both the 'history' and 'tabs' permission, one should hide the

// permission, only the new coalesced message is displayed.

// AntiTest: This behavior should be changed and improved.
// If an app requests the 'tabs' permission but already has the 'history'
// permission, a prompt is displayed. However, no prompt should appear at all,
// since 'tabs' is a subset of 'history' and the final list of permissions are
// not affected by this grant.

// permission request prompt. However, the required permissions for the app are
// actually modified, so the prompt *should* display a message to prevent this
// permission from being granted for free.
