Testing Wallaby.js with TypeScript and jest.mock
The jest.mock calls need to be hoisted above the require calls to make them work. This is done by babel-preset-jest via ts-jest. With wallaby this transform is apparently not applied.
Run yarn or npm install.
Run yarn test or npm test.
The one test should be succesful.
Start wallaby in the IDE of your choice.
The test will probably fail. Fixed with #1.
