Unable to use Test.use() at individual test level about playwright

[kasperpeulen]

We cannot .use in void

I know, just suggesting an idea.

I found out that this does work:

test.extend({ fixture: 'some fixture' })('some test', async ({ fixture }) => {
  // test
});

On runtime it works, but it gives TS errors. And of course is also quite ugly.

It would be interesting if you could attach use like this:

test('some test', async ({ fixture }) => {
  // test
}).use({
  fixture: 'some fixture'
})

[Ransely-Nigrel]

.use({
  fixture: 'some fixture'
})

We cannot .use in void

The original issue refers to the Cannot use({ headless }) in a describe group, because it forces a new worker error. For the fixtures that force new workers (run browsers in a different mode), this will remain to be a hard limitation. You can't have headed and headless tests in the same file.

As for the .use on a test level, please use anonymous describes to wrap those tests and define use. As use refers to the scope and is not chained, that's the only way we'll support it.

Can you comment if this is expected to work:

test.extend({ viewport: someViewport })('some test', async ({ fixture }) => {
  // test
});

it does work, but it gives TS errors
