Jest-dom: Codesandbox expect is not defined

[viniciusavieira]

• jest-dom version: 3.1.3
• react-testing-library version: 6.0.0

Relevant code or config:

https://codesandbox.io/s/ymjjk77x0z

What you did:

There are 2 files in the __tests__ folder, one imports jest-dom and another does not.

ErrorFormatDateView.test.js Does import jest-dom and breaks by not finding the expect export.

FormatDateView.test.js Does not import, and using other matches can pass the test case.

Suggested solution:

jest-dom/extend-expect should export a default expect from jest.

This is a codesandbox bug

Cc @compuives, of all the things that codesandbox could do, this is the number one thing I would like: fix the testing story so this works like it used to.

[CompuIves]

I'll make sure to put the fix in the update tomorrow!

[viniciusavieira]

I've tested it today and seems to be working fine.

Thanks for the effort guys.
Thanks @CompuIves!

Wanted to bring this issue back up, as there's another issue having similar problems in running unit tests from CodeSandbox:

https://github.com/codesandbox/codesandbox-client/issues/2311

Trying to run unit tests from the CodeSandbox above doesn't work, it just stagnates and nothing happens.

[CompuIves]

Fix is underway!
