How to run a list of test suites in a single file concurrently in jest?

Is it possible to get the selector from a locator object in playwright?

firefox browser does not start in playwright

Running Playwright in Azure Function

Jest + Playwright - Test callbacks of event-based DOM library

firefox browser does not start in playwright

Assuming you are not running test with the --runinband flag, the simple answer is yes but it depends ????

There is a pretty comprehensive GitHub issue jest#6957 that explains certain cases of when tests are run concurrently or in parallel. But it seems to depend on a lot of edge cases where jest tries its best to determine the fastest way to run the tests given the circumstances.

To my knowledge there is no way to force jest to run in parallel.


Aside

Have you considered using playwright instead of puppeteer with jest? Playwright has their own internally built testing library called @playwright/test that is used in place of jest with a similar API. This library allows for explicitly defining test groups in a single file to run in parallel (i.e. test.describe.parallel) or serially (i.e. test.describe.serial). Or even to run all tests in parallel via a config option.

// parallel
test.describe.parallel('group', () => {
  test('runs in parallel 1', async ({ page }) => {});
  test('runs in parallel 2', async ({ page }) => {});
});

// serial
test.describe.serial('group', () => {
  test('runs first', async ({ page }) => {});
  test('runs second', async ({ page }) => {});
});

7 Skills of a Top Automation Tester in 2021

With new-age project development methodologies like Agile and DevOps slowly replacing the old-age waterfall model, the demand for testing is increasing in the industry. Testers are now working together with the developers and automation testing is vastly replacing manual testing in many ways. If you are new to the domain of automation testing, the organization that just hired you, will expect you to be fast, think out of the box, and able to detect bugs or deliver solutions which no one thought of. But with just basic knowledge of testing, how can you be that successful test automation engineer who is different from their predecessors? What are the skills to become a successful automation tester in 2019? Let’s find out.
