How to extend mocha context in typescript?

Question

JavaScript

Hello. Actually, I have global hooks that create a piece of data and write it to this . Naturally, these variables remain untyped in my tests. I would like to fix this by extending the Context with d.ts

What I tried:

declare namespace Mocha {
    class Context {
        client: IClient;
        bus: IBus;
        testNumber: number;
        connectionParams: ConnectionParams;
    }
}

Also in tsconfig in the files section I added the path to this file. But I'm still not shown the type of these variables.
I know that the key [key:string]: any is described there , so I removed it to see the result more accurately and ts began to fall.

Maybe someone has already encountered this, because in my opinion it should be something standard when writing tests on ts

Answer 1

it's easiest to type this in handlers
it( 'my test', function (this: MyContext) {})
