What is this?

This is a small sample for using Angular's fakeAsync test helper in a nest.js application.

Most of the code was autogenerated by the awesome nest cli. There are two main files of interest: spec/test.spec.ts shows a small working demo of the fakeAsync function in action. helpers/fakeAsync.ts contains the actual function definitions. You may also be interested to look at the contents of the package.json.

How did we get here?

I first created a new nestjs service with

nest new fake-async

Then I installed the necessary dependencies.

npm install --save-dev zone.js @types/zone.js

I then installed and set up jasmine

npm install --save-dev jasmine @types/jasmine

Then I created fakeAsync.ts. Of import: the right import statements at the top.
