@razvanpapadopol, according to #40135, did you want to add some of the new tests to canaries?

In my opinion this would be mostly redundant, covering a large part of the flow tested already by the signup tests. What do you think about adding this step to an existing canary signup test?

[Stojdza]

Full e2e suite is running two times every day. If you think it's enough for testing launch flow then I would skip adding it to canaries. If launch is important and prone to changes, then feel free to add it to signup canary.

Running this against PRs (with needs review label) and on scheduled runs seems good for now. Adding and removing it from canaries is pretty trivial, right?

@gwwar any reason you wanted this specifically for canaries? #40135

Yup. Just mark test with @canary tag. For example:

describe( 'Launch a free site @canary', function ()

[razvanpapadopol]

Yes, but that will add the whole test preparation and cleanup as well to canaries (create account, create site, delete account) so I suggested instead to just add a single step to the complete signup flow that we already have:

step( 'Can launch a site', async function () {
    return await new LaunchSiteFlow( driver ).launchFreeSite();
} );

@gwwar any reason you wanted this specifically for canaries?

Because it broke before :D If it's too heavy, it's fine to leave it on the full suite.

@Stojdza Added the extra step to canary signup in 1a1587c

Is there anything I can do about the remaining failing e2e tests? (Rebased and re-run tests a couple of times).

[Stojdza]

@razvanpapadopol I tried failed tests locally, against WP.com and live branch, and they passed. You're good to go 👍
