Re: [QF-Test] File download from firefox

Hello Marek,

if you open the browser using the WebDriver connection mode (which is always the
case if you like to test with a Firefox browser newer than version 43), the
automatic dialog handling is currently not available (due to restrictions of the
WebDriver W3C protocol, which has no support for controlling such boxes).

In fact, you already named the options we can provide. Some small complementary
information:

* QF-Test 4.2 comes with the uiauto scripting module, which allows fine control
over Windows controls using the UIAutomation API. These would probably offer you
more options than the classic autowin.

* For the proposed direct http-download, you can use a jython script with the
urllib2 module [1], which provides options for Authentication

* The easiest way would be to set the firefox settings to direct download. You
can do this using a jython SUT script in your browser startup sequence, after
"Start Web-Engine", but before "Open Browser Window":


import tempfile

folder = tempfile.mkdtemp(".downloads")
rc.setGlobal("downloadFolder",folder)

rc.engine.preferences().setIntPref("firefox","browser.download.folderList",2)
rc.engine.preferences().setBoolPref("firefox","browser.download.useDownloadDir",True)
rc.engine.preferences().setStrPref("firefox","browser.download.defaultFolder",
folder)
rc.engine.preferences().setStrPref("firefox","browser.download.dir", folder)
rc.engine.preferences().setBoolPref("firefox","pdfjs.disabled",True)


You can also force the download of specific files by listing their mime types:

rc.engine.preferences().setStrPref("firefox","browser.helperApps.neverAsk.saveToDisk",
"application/x-xxxx, ...")

Then you can pick the file from the specified directory (stored in the
downloadFolder variable), possibly using a regular expression (due to the
timestamp in it).

Sincerely,
  Pascal Bihler
