执行 TestCafe 断言的正确方法是什么

Question

I am basically stuck between a rock and sort of a hard place. I'm writing some automation scripts using TestCafe and I need some help on best practices. Basically I would like to know the best way to create an assertion that waits a brief period of time until an element appears before executing.

My Current implementation:

const setTimeout = 5000;

await t
    .expect(this.papernote.exists, { timeout: setTimeout })
    .ok('The trail is not visible');

When the test executes, it seems like the timeout does not get respected. Meaning TestCafe will wait the default time (3 seconds I believe) then the assertion will fail

Answer 1

I hope you want to increase the selector timeout. Try using this flag

--selector-timeout 500000

and you can also try

--assertion-timeout 10000

or you can try waiting for the element,

await element.with({ visibilityCheck: true }).with({timeout: 10000});

If you need to define a timeout for a particular assertion, pass the options object to the ok method:

await t
    .expect(this.papernote.exists)
    .ok('The trail is not visible', { timeout: setTimeout });

See the documentation article for details: https://devexpress.github.io/testcafe/documentation/test-api/assertions/assertion-api.html#ok
