[Question] Is `count` on Locator working as expected?

So I have a locator for this selector here like this

const foo = '.tab-content table#outer-table > tbody > tr:not(#inner-table-row) > td'
const el = await page.locator(foo).count()
console.log(el)

I wanted to do an assertion on the number of elements retrieved, so count() seemed appropriate. However when I log out the count I see 0 and this warning

Uncaught exception: Error: strict mode violation: ".tab-content table#outer-table > tbody > tr:not(#inner-table-row) > td" resolved to 50 elements:

So the selector resolved to 50 elements:, yet the count of those elements is 0?

How can that be?

@vomc the rule of thumb is to always prefer web-first assertions!

To assert count, you should use expect(locator).toHaveCount(50)

Ah! yes that works, thank you @ltsuda ! To me as a beginner in Playwright this was not obvious from the documentation. Since it returns a Promise, I assumed that it would get the total count once the page is loaded.
