There are times when our React components use lifecycle methods like componentDidMount. In this lesson we will make sure that we write tests to make sure that these methods are called. This includes testing that our component utilizes componentWillReceiveProps correctly.

I am using typescript, it is throwing error for ..componentDidMount.mock.calls .. . The error is Property 'mock' does not exist on type '() => void'.

It seems is not a typesafe operation. Is there a workaround for this? Found https://jestjs.io/docs/en/mock-function-api#mockfnmockimplementationfn
