Running tests in the browser

[pspeter3]

It would be great for a TDD setup to be able to run the tests in the browser and see the component you are trying to test. Is it possible to run jest in the browser?

[pspeter3]

Specifically I just want the ability to run a single jest test file

There was some discussion about this on the mailing list.

is there a way that jest could make use of the jasmine spec runner?

Anyone has any update on this? Is there any work in progress?

[danvk]

We migrated our tests to Mocha for this reason, among others. I'd highly recommend doing the same (or to Jasmine). While we still can't run our tests in-browser (they depend on fs and other node modules that don't make sense there), we can at least use node-inspector, which is almost as good for debugging.

[pspeter3]

We migrated our tests to mocha as well. We use browserify to run them in the browser and jsdom to run them on the command line.

Thanks a lot for the feedback guys 😄

Nothing done here yet, as the auto-mocking requires the node runtime environment.

[facundocabrera]

Why do not provide a working version without auto-mocking? I remember https://remysharp.com/2014/05/30/commonjs-with-devtools-live-edit so it should not be impossible to do this limited version.

I know PR are welcome!

i would also really appreciate using the specrunner!

The important issue here is the ability to use the browser to debug the unit test in the browser. It's very useful to debug the code you're testing, rather than a run-and-see-if-it-works setup. Really helps in a TDD environment

[kiki-le-singe]

if there is no possibility to test in browsers, how can we debug?
