Not using the local executable throws "Page Crashed!".

In the past we have been adding a lot of additional functionality into single commands like click to serve different purposes. Are you reusing tabs/browsers?

In console: https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#tips, I still had this Error: Page crashed with '--disable-dev-shm-usage' on Ubuntu 16.04 even with. Also trying to run this on Windows 10 and getting the same error. I'm also getting a similar result with trying to run lots of puppeteer tests in parallel.

That said, we generally recommend to update to the latest version as soon as possible to make sure that you leverage bug fixes that have been made to the project.

Thanks for contributing an answer to Stack Overflow! My guess is that when the entire test suite is running, there is a global navigation timeout which exceeds the limits of 30000ms. If you use the WebdriverIO API the experience using WebDriver vs Puppeteer should be the same, running commands on Puppeteer might even be a little faster. Now jest-puppeteer will run npm run serve, with a timeout of 180 seconds (3 minutes), and listen on port 9000 to see when it will be up.Once the server starts the tests will run. This major update is far less "breaking" than the one last year.

We’ll occasionally send you account related emails.

What aspects of image preparation workflows can lead to accidents like Boris Johnson's No. Cascading common emitter and common collector. Locally it was fine, but it would fail when running inside the CircleCI docker containers. I have a small suite of tests based on Puppeteer with Jest, and I can't get rid of the following problem: when I am running a single specific test (ex: yarn test myscenario.test.js) everything works just fine; the problem occurs when I am running the entire test suite (about 20 tests) using yarn test command, some of my tests are failing with following error: Navigation Timeout Exceeded: 30000ms exceeded We recently switched to 3.3.0 version and started getting this issue.

Note: using Puppeteer instead of WebDriver is only supported if running tests locally and if the browser is located on the same machine as the tests. You can find a detailed description on how to install NVM and update Node in their project readme.

and a single test is executed in about 6-7 seconds.

This is a rather specific case, but I hope it helps someone. ... We chose cloud tools that would allow us to run many tests in parallel, and integrated well with our existing build and deployment systems.

But after some refactoring of my code, the tests would fail as before. Also, did you try to launch in non-headless mode to check what exactly is happening during the test execution?

Asking for help, clarification, or responding to other answers. I'm starting to think that you're running out of memory.
