Requirements

Endform is a fully parallel, remote test runner. Each of your playwright tests will be run on a separate machine in the cloud.

Fully parallel

Section titled “Fully parallel”

All of your tests will run at the same time with endform, which means that your tests need to be completely independent of each other.

If you keep your tests decoupled from your application already by, for example, using apis to generate data, you are probably ready to use endform.

Remote

Section titled “Remote”

Since your tests will be running on remote machines, your test environment needs to be accessible on the public internet. Endform does not support servers running “locally” / on localhost.

We reccomend using playwright directly when creating tests / running against localhost, and to run endform in your ci environment / against your test/stage/preview environments.

Playwright Requirements

Section titled “Playwright Requirements”
  • We support playwright projects written in typescript and javascript.
  • The length of an individual test run is limited to 4 minutes (same as the testConfig.timeout option). The playwright default timeout is 30 seconds. This does not include retries.
  • We currently only support the latest minor version of playwright (1.53.0 at the time of writing).
  • We currently only support Chrome. We run the same version of Chrome as the playwright version you are running ships with.

Playwright Configuration Options

Section titled “Playwright Configuration Options”

Endform tries to directly use or replicate all playwright configuration options. To understand how most of these options work, please refer to the Playwright documentation.

There are a few exceptions to this.

Options that we currently don’t support, but will do in the future (let us know and we will prioritize them):

  • forbidOnly
  • the on-all-retries, on-first-retry, retain-on-first-failure trace recording options. If you are using one of these, we will override the config to use retain-on-failure. off, on and retain-on-failure are our reccomended options for trace recording.

Options that aren’t supported since they don’t make sense in a remote context:

  • webWorkers
  • fullyParallel is always true

Node Requirements

Section titled “Node Requirements”
  • A version of Node.js that is more recent than the latest LTS version (Node 22+).
  • In the remote test environment, your tests will run on node lts.

Browser Requirements

Section titled “Browser Requirements”
  • We currently only support Chrome. We run the same version of Chrome as the playwright version you are running ships with.

Operating System Requirements

Section titled “Operating System Requirements”
  • We currently only support Linux and MacOS.
