Getting a "ShadowRoot is not defined" error #293
Comments

@peripateticus Thanks for opening an issue This is indeed a problem with vue-next and not in vue-test-utils-next, and you're intuition is right. The good news is that there is already a fix ready to merge vuejs/core#2943 I'm going to close this issue, as there is nothing we can do on VTU-next side. |

Excellent, thank you for the quick response and pointing me to the fix on this, @cexbrayat! 👍 |

fixes an issue in browsers where ShadowRoot is not available globally (e.g. Edge 18). Error message is "ShadowRoot is not defined". A similar issue was reported here vuejs/test-utils#293 and the fix was referencing ShadowRoot from window instead: https://github.com/vuejs/core/pull/2943/files

Hello!
So, we are in the process of upgrading Vue 2 -> 3 and, for unit tests, we use a combination of mochapack and
@vue/test-utilsfor unit testing. Currently, I'm testing with@vue/test-utils@2.0.0-beta.14.What is happening is that when I mount the component in the
mochaspec file, I hit this error:Looking at the error stack at line 1261 in the
@vue/runtime-dom/dist/runtime-dom.cjs.jscode, it says thatShadowRootis undefined. So, in the code, if I change that to awindow.ShadowRoot, it's happy. I see thatwindow.ShadowRootexists whenJSDOMis set up, prior to when the tests run.Any ideas? Thanks for the help!
