Add support to set the default download path for chrome

[IwanVosloo]

Hi,

I have tried to manually set the default download path for chrome using a DesiredCapabilities object:

desiredDriverBrowserCapabilities
  ^ BPDesiredCapabilities chrome
"    setCapability: 'chromeOptions'  << also tried this"
    setCapability: 'goog:chromeOptions'
          to:
            (Dictionary new
                at: 'prefs'
                put:
                  (Dictionary new
                    at: 'download.default_directory'
                    put: '/tmp/testdownloads';
                    at: 'download.prompt_for_download'
                    put: false;
                    at: 'download.directory_upgrade'
                    put: true;
                    yourself);
          yourself);
    yourself

I could not get that to work. I suspect there are a lot of things related to the internals of WebDriver and chromedriver that I'd have to understand better.

If you trawl the web on the topic, you find a lot of references for setting this using the ChromeOptions object .

It would be super if such an object was available in Parasol or even if there was a bit of documentation for how to get this task done with what is available at present.

I've put together a Java test based on the answers to the StackOverflow question:

Test Chrome Download Directory.zip

The output shows what is actually passed as desired capabilities:

    [junit] Testsuite: Tests
     [exec] 11:44:48.413 INFO [ActiveSessionFactory.apply] - Capabilities are: {
     [exec]   "browserName": "chrome",
     [exec]   "goog:chromeOptions": {
     [exec]     "args": [
     [exec]     ],
     [exec]     "extensions": [
     [exec]     ],
     [exec]     "prefs": {
     [exec]       "profile.default_content_settings.popups": 0,
     [exec]       "download.default_directory": "\u002fvar\u002ffolders\u002frv\u002f5k6p15048xj49y001s63pbbh0000gn\u002fT\u002ftestDownloadDirectoryOption5398117482515693748"
     [exec]     }
     [exec]   }
     [exec] }
…
    [junit] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 10.373 sec

I haven't tried it in Pharo yet, but maybe this helps you figure it out? Note that for download.default_directory, the path separator seems to get encoded as \u002f; maybe that has something to do with it?

Thanks for replying... my problem turned out to be in my own code that was using the above correct code incorrectly. So what I posted above actually DOES work.

Some notes for future reference:

• Different answers on stack overflow suggest setting a number of preferences together with the download directory, and the answers differ. For me setting only "download.default_directory" was sufficient. (Perhaps I still have to encounter more corner cases?)
• I did not have to encode the directory itself in any special way.
• I am a bit confused as to whether to use "chromeOptions" vs "goog:chromeOptions". The latter is what is used in java code, but from the use here I gathered "chromeOptions" also works. According to my experiments both work.
