I was trying my hand at creating an e2e test by going off some existing tests and I was getting unexpected results. It turns out the example I was following may have had problems, as I found that if I replaced the Import Complete. in this diff with garbage text, the test still passed without complaint. I looked for other examples and found that changing to expect(...).toBeVisible() did what I think was intended, as now it chokes on garbage text but runs successfully when it sees the Load Successful pop-up. However, one snag remained in that the linter complained error: Expect must be inside of a test block. I figured out how to adjust the linter rules to allow this, but if there's a better way to go about this, I'm all ears.
