QUESTION
I have red swiggly lines in visual studio code even when the variable is defined (error message).
If I disable eslint it will go away, but I don't think that's the correct approach and this would stop linting the rest of the ts/js files. (I have ESLint extension installed)
I have Visual Studio Code: 1.57.1 (Universal) on Mac OS Catalina.
I can right click and go to the browser
definition.
ANSWER
Answered 2021-Jul-08 at 19:31Eslint does not know about global variables. To solve this, you have two options:
- Tell eslint which variables are defined
- Disable the eslint rule that checks for undefined variables
To tell eslint which globals are defined, add them to your eslint config file
QUESTION
If one were to start a brand new project and we want to use Playwright with TypeScript for front-end testing, would you recommend we use Playwright-test or Jest-Playwright-preset as the test runner? Please indicate why you would pick one over the other. Thank you!
...ANSWER
Answered 2021-Jun-30 at 08:34I would recommend Playwright Test, because
- it works without other external dependencies
- has support for TypeScript out of the box
- has multi-project support with different browser configurations
- Supports trace-viewer, video, and screenshot creation out of the box via the config.
- Applies context per test best practice to have them isolated and self contained

QUESTION
I have a project with E2E tests setup with Playwright + TS-Jest. To organize my tests I use Page Object Model. Structure looks like that:
I wanted to use TypeScript paths
option in tsconfig.json
to clean up the imports both in test files as well as in POM classes. After some trial and error I came up with the following config files:
ANSWER
Answered 2021-Jun-14 at 15:04I've managed to find solution in this GitHub issue: https://github.com/kulshekhar/ts-jest/issues/1107#issuecomment-559759395
In short, by default ts-jest
transform is invoked later than it should, so doesn't have a chance to process all the files. The tsconfig-paths
can help with that:
- Install above package with
yarn add --dev tsconfig-paths
- In
global-setup
file addrequire('tsconfig-paths/register');
at the very beginning of the file.
All the absolute imports should work.
QUESTION
I'm trying to take a screenshot of a failed testcase using Jest
and PlayWright
, the handling function is defined in a custom environment as seen below
ANSWER
Answered 2021-Apr-18 at 20:36There are deliberate specialized cases you may want to use page.close() in a custom fixture/config but I'm wouldn't say that's the case for you based on what you're trying to do. By default, the browser/context will close automatically after each test, and will therefore also close the page being tested. You can see the default teardown here.
Removing your afterEach method should resolve the issue. :)
Other notable features:
- Checkout Playwright-Test to see how custom config/fixtures can help you make consistent test environments, (ie. if you wanted some environments to take screenshots
only-on-failure
but not others. - Playwright also supports page object models -- a feature that makes your tests much more readable and maintainable. I also have an example here that you can reference for Page Object Models with the new version of Playwright, if this helps.

I am using Playwright with Jest and jest-playwright-preset and trying to get my tests to run in GitLab CI.
My .gitlab-ci.yml:

Answered 2020-Jun-29 at 17:53The node:latest
does not have the appropriate system dependencies to run the browsers. You can use the Playwright docker image.
