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
Jest + Playwright - Test callbacks of event-based DOM library
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 }) => {});
});

JUnit is one of the most popular unit testing frameworks in the Java ecosystem. The JUnit 5 version (also known as Jupiter) contains many exciting innovations, including support for new features in Java 8 and above. However, many developers still prefer to use the JUnit 4 framework since certain features like parallel execution with JUnit 5 are still in the experimental phase.
