Description
I followed the instructions for setting up testing on my Ionic project, but I got the error `Uncaught Error: Module build failed: TypeError: Cannot read property 'afterCompile' of undefined`
After some investigation I realized that Ionic uses webpack 3, but the default version of `ts-loader` installed with npm install is for webpack 4. Please update the blog entry to install a 3.x.x version of ts-loader.
For anyone facing this error you can simply install the correct version of ts-loader manually like this...
```
npm uninstall -D ts-loader
npm install -D ts-loader@3.x.x
```
