'Run the Tests' not working (React and Redux - Front End Libraries)

[Cyhyraeth]

Getting Started with React Redux

Above is a link to the page I’m having trouble with. In the console below my code it says /* Your test output will go here. */ and then when I click ‘Run the Tests’, no matter how long I wait or what the code is, it just says // running tests. I’ve tried it both with code that should pass all tests and immediately after clicking ‘Reset All Code’ to try it before changing anything.

Also, it was working for me before. I actually already completed the page that I linked at the top of the post and was just doing it again for review before starting on the second challenge (which I have not completed yet). The ‘Run the Tests’ button is not working for me with either page/challenge.

Edit: This following error is logged to the browser console after clicking the ‘Run the Tests’ button:

I am also getting this issue and have tried on multiple devices

I am in just the React section, and have a similar problem with the tests not running on “Create Simple JSX Element”. I’m following in case it can be resolved the same way. This is what I found in the console:

I noticed the same thing and posted before finding this thread:

Test Button on React lessons does not function properly

I noticed the 'Run the Tests" button does not work for me at least on this lesson: https://www.freecodecamp.org/learn/front-end-libraries/react/create-a-complex-jsx-element Console Error: Request to access cookie or storage on “https://unpkg.com/react-dom@16.4.0/umd/react-dom.production.min.js” was blocked because we are blocking all third-party storage access requests and content blocking is enabled. create-a-complex-jsx-element When I added freecodecamp.org to my third-party cookies whitel…

Might be a problem with dependencies they have:

We have just invalidated our CDN cache to fix this, can you all please try and check again? Here is a thread if you want to learn more:

React, Redux Tutorials Tests are not executing

This seems like a caching issue. I noticed that our webpack config for the client/src/client (workers, frame-runner, etc) do not create a hashed binary. A recent PR seems to have updated the enzyme package. But webpack builds a non-hashed version '[name].js' instead of '[name].[hash].js' Our CDN caching aggressively caches JavaScript and this is the root cause. As an immediate fix I have invalidated our cache, which means a perf hit to us. But the real issue is we need to see why webpack is be…
