File Tree Diff: the test is failing

[humitos]

I'm not sure what happened, but after merging the PR that added the FTD test into #504, that test started to fail. I need to research why and fix it.

I researched this a little, but I wasn't able to find the cause about why the snapshot is not being loaded by web test runner. Deleting the snapshot file makes the test to pass, which doesn't make sense to me.

Also, running web-test-runner --update-snapshots after deleting the file, does not regenerate it. It's like this line

addons/tests/filetreediff.test.html

Line 66 in f572e9e

await expect(element).shadowDom.to.equalSnapshot();

wouldn't exist 🤷🏼 cc @agjohnson any idea why this could be happening?

Meh, I found the issue. I was reading the actual / expected message in the wrong direction 🤦🏼

I needed to add versions.current.type: external in the config object used in the test. It works now 👍🏼

Fixed in #535
