Hi there!
While working on Firefox log capturing for a project (basically it requires setting
devtools.console.stdout.contentasmoz:firefoxOptions > pref) I discovered the FirefoxManager behavior regarding options merging looked strange:as soon as one sets the
moz:firefoxOptionsalmost all the automation is gone (binary, args, and default prefs are gone).While redefining most of them could be okay, this makes configuration via environment variables inoperant out of the blue, which is not in sync with how ChromeManager works.
This also drops the sensible defaults FirefoxOptions.
This MR tries to address this issue.
It is not easy (or even possible) to introspect the
moz:firefoxOptionssent to the browser by connecting to it. I didn't find anywhere to hook into the library to check our required capabilities. This is why I took the liberty to introduce a new private method and access it via the reflection in the test suite. This is not the best but I don't see another way atm. Any suggestion is welcome!(PS: I also added some basic tests for the
FirefoxManagerbased on theChomeManagerones)
