Help Requests
1

Here is my configuration on a new app using latest aurelia-cli v1.0.0-beta.9 (1/17/19)

Platform: Web
Bundler: Webpack
Loader: None
Transpiler: TypeScript
Markup Processor: Minimal Minification
CSS Processor: Sass
Unit Test Runner: Karma
Integration Test Runner: Protractor
Editor: Visual Studio Code

I haven’t modified anything. I built the app, then I tried to run au karma with the following error. Any clues?

Local aurelia-cli v1.0.0-beta.9

There are few issues related to cli webpack+karma recently, not fixed yet. You can find them in cli github issues.

Meanwhile, you can try use jest au jest.
Both jest and karma test setup were provided in the app skeleton generated by au new.
