A guide to utilizing the await method with fixture.whenStable in Angular 2 testing

https://i.sstatic.net/XrLpH.png

Even though the function whenStable returns a promise, I am unable to use await in this context.

Here is my current tsconfig configuration:

"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5",
"typeRoots": [
  "node_modules/@types"
],

The version of TypeScript being used is "typescript": "^2.1.5"

Answer №1

If you see the error message saying 'await' is only allowed within an async function, it means that in order to use await, you need to mark the outer function with the async keyword.

// For example

const myAsyncFunction = async () => {
   // ... some code
   await fixture.whenStable();
   // ... some code
}

By marking any function with the async keyword, it will return a promise. To understand more about async/await, check out this question.
