Running Playwright in Azure Function
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 }) => {});
});

Getting Rid of Technical Debt in Agile Projects
Technical debt was originally defined as code restructuring, but in today’s fast-paced software delivery environment, it has evolved. Technical debt may be anything that the software development team puts off for later, such as ineffective code, unfixed defects, lacking unit tests, excessive manual tests, or missing automated tests. And, like financial debt, it is challenging to pay back.

A Complete Guide To CSS Houdini
As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
