How to run a list of test suites in a single file concurrently in jest?
Jest + Playwright - Test callbacks of event-based DOM library
firefox browser does not start in playwright
Is it possible to get the selector from a locator object in playwright?
Running Playwright in Azure Function
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.
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 }) => {});
});

The web development industry is growing, and many Best Automated UI Testing Tools are available to test your web-based project to ensure it is bug-free and easily accessible for every user. These tools help you test your web project and make it fully compatible with user-end requirements and needs.
Recently, I was going through some of the design patterns in Java by reading the book Head First Design Patterns by Eric Freeman, Elisabeth Robson, Bert Bates, and Kathy Sierra.
Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.
Manual cross browser testing is neither efficient nor scalable as it will take ages to test on all permutations & combinations of browsers, operating systems, and their versions. Like every developer, I have also gone through that ‘I can do it all phase’. But if you are stuck validating your code changes over hundreds of browsers and OS combinations then your release window is going to look even shorter than it already is. This is why automated browser testing can be pivotal for modern-day release cycles as it speeds up the entire process of cross browser compatibility.
