[task] unit tests for essential functionality

[myrdd]

In this first post I'll collect all unit tests that are possible or are planned. If you have ideas, please let me know. :)

• links
  • an url can be opened …
    • … in the same tab
    • … in a new tab
    • … in a new window
    • … in a new private window.
  • clicking on HTML <a> Elements. see Opening a link as new tab blocked #480
  • select a text link --> right-click --> open link.
• redirects
  • types of redirects
    • HTTP Location and Refresh headers
    • changing document.location in JavaScript.
    • <meta http-equiv="refresh" …> HTML elements
  • check that the redirect bar appears when blocking by default
    • when opening a new page that redirects
    • when clicking on a link that redirects
    • when opening a link in a new tab/window (redirect bar should appear in the correct tab)
    • when an embedded object (image, iframe, ...) is redirected
  • check if all buttons on the redirect bar work.

_unsorted ideas:_ (for some of the problems there might be already a mozmill test by mozilla)

• Backend
  • does the upgrade from 0.5.* work (are the user policies imported?)
  • test whether "other origins" are recognized correctly.
  • check different schemes,
    • e.g. about:addons (Cannot look for addons in addon manager #478)
  • check whether RequestPolicy starts up fast enough to catch all requests
  • check whether severe errors have appeared in the log – in any test.
  • check whether different types of requests are catched at all (using wireshark etc.?) – see also WebRTC requests are not filtered #586
• User interface
  • whether the settings pages work correctly
  • ensure that the setup tab is opened after install (Initial setup doesn't appear when firefox set to restore session on start #479)
  • whether the menu is populated correctly.
    • whether [no origin] is displayed correctly
• Browsing
  • link click and subsequent iframe to same link should not allow iframe.
  • history: back and forward
  • open the same url in several tabs/windows (Opening the same site in multiple windows confuses RequestPolicy (1.x) UI #366 is possibly a bug)
• Website-specific
  • test sites with many links and other objects (see e.g. Performance issue: eBay announcement pages #369)
  • onerror "loops" – Javascript code in onerror attributes run forever #441
• about:addons should work (installing addons)
• test loading of an erroneous json file

_non-essential tests_

• Do not put placeholders for blacklisted images #506
