Hi, Thanks for trying to improve the tests! I'm reluctant to give up Firefox sanity tests on every commit, though. In fact, I wanted to add Edge and Safari, because those are also supported browsers. Just today a Firefox only issue was reported, so they are valuable. Did you consider either leaving a grid up permanently or perhaps using a third party like saucelabs?

Did you consider either leaving a grid up permanently or perhaps using a third party like saucelabs? I did consider simply having our own grid for the OST. There's even a thread somewhere on ovirt-devel, where someone found OST trying to connect to one of my VMs in Tel Aviv, where my own grid was running :D I couldn't make a public demo though - OST executors couldn't see my VM in tlv. This approach has 2 big flaws: - it requires quite a lot of resources for the grid to always be there for us What about Saucelabs or another third party free tool?

- it makes OST running times somehow undeterministic - situations, where WebDriver has to wait for Selenium hub/nodes to be free, will probably take place The way I see basic suite's UI sanity tests, is that they're exactly what they're called - sanity tests. We do trivial checks like "can we log in to the webadmin site", "can we go to 'virtual machines' sub-page". I'm not in favor of dropping these completely - I think they make sense, but I also think we can live with a trimmed-down version that saves a lot of time. As I said - AFAIK QE have their own Selenium grid, where they run more complex tests on the UI.

Marcin, It just dawned on me that the main reason 008's start_grid takes so long is that the docker images are fresh pulled every time. Several hundred MB, every time (ugh, sorry). We can and should cache them. What do you think about trying this before doing anything else? [it would also be a good time to update from actinium to the latest, iron.] @Barak Korren <mailto:bkorren@redhat.com> you once mentioned to me we should cache these if they are ok to cache (they are).

Was the Firefox-only issue detected by basic suite or some other tests? It was reported by a developer. Because GWT compiles permutations per browser, and each browser therefore loads completely separate JavaScript payloads, it's just too easy for it to break in one browser and be fine in the other, so I'm really not ok to remove Firefox. If Admin Portal was React where there is a single JavaScript payload that's shared among all browsers, then I'd consider it. > > Did you consider either leaving a grid up permanently or > perhaps using a third party like saucelabs?
