Your need to use fake timers here. After all imports call jest.useFakeTimers(). Then in test after mounting the component call jest.runTimersToTime(2500). And after that you can do your assertions. Test example:

I'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 add require('tsconfig-paths/register'); at the very beginning of the file.

All the absolute imports should work.

A simple way to make your test case pass is to check if the whole argument is passed to your mock function instead of checking part of the arguments. 😂

Webpack compilation failed in react-native-web on {Node} i.e. Flow Syntax saying "You may need an appropriate loader to handle this file type"

Asked 2021-Jun-12 at 15:49

I am new to node/npm, react and react-native so very new to react-native-web as well. It's been 3 days for me to integrate react-native-web in a Hello World App generated using npx react-native init as per the doc. I tried using both templates: with and without typescript, but no success so far. The farthest I got is to run the app code written in index.web.js but if I add any component from ./src/components/ then I get errors, mostly of webpack.

I created a test repo for easy regeneration of error, So Steps to reproduce are as below:

Download this repo in your system.
npm install
npm run web

Now you'll see the error in the terminal.

Versions:

metro-react-native-babel-preset: 0.66.0
node: 16.3.0
npm: 7.8.0
OS: Windows 10 - 64 bit

I followed official documentation but with webpack@^4 and referred this article and somehow managed to reach the below situation:

Webpage is getting rendered if my whole code is inside index.web.js.
But when I import App inside this then I get compilation failed due to loader error.

Working index.web.js:

Finally, It's been resolved, my Hello World is done.

These 2 replies from the maintainer himself (@necolas) on this discussion helped me to get the issue.

Reply 1 by @necolas This line in the stack trace is telling you that you're trying to bundle RN internal code in your web bundle: node_modules/react-native/Libraries/NewAppScreen/index.js.

First, you should not be loading any of the RN package on web, especially not parts that aren't part of the public API . Second, as mentioned in the inline comments of the config you pasted above, you need to explicitly list everything in node_modules that needs compiling.
