            Okay, I was able to get this working but I am not sure why I had to do it this way after it's been working for over a year with the current system. I even have other devs using it with no issue. Very strange.

            To get this working, I had to make a simple change.

            deal when several extended matchers with same name
            Asked 2020-Sep-24 at 09:17

            I am using custom matchers from two external libraries jest-dom/extend-expect and jest-extended. Both libraries defines a matcher named toBeEmpty, but with different behaviour. One expects a string/array/object/iterable to be empty, the other expects a DOM element to be empty.

            My feeling is that the order in jest configuration impacts which matcher is actually used in test:

            expect.extend merges matchers into matcher object, matchers with same names are being replaced without a notice, this is a known problem.

            A way to prevent name collisions is to provide namespaces for matchers and set them in Jest setup file specified in setupFilesAfterEnv. Matcher functions can be imported directly from matcher libraries and supplied to expect.extend.

            @testing-library/jest-dom provides public entry point to import matchers:

            Is it possible to use EaselJS (CreateJS) with TypeScript using parceljs?
            Asked 2020-Jul-21 at 01:22

            I'm trying to make a game with EaselJS, and since it's [current year], I'm using TypeScript. There are "official" types that I'm using from here, but I can't get it working together with parceljs. If I import the types, parcel fails. If I import without types, parcel is happy (and my build works), but I've got no types in VS Code.

            Here's my import, which works for the parcel build:

            I found a workaround. Use the createjs-module package instead, and use this as your import statement:

            Error Mocking Firebase Admin in Jest: "TypeError: admin.firestore is not a function"
            Asked 2020-May-12 at 06:55

            I have a function to handle connecting to Cloud Firestore through the Admin SDK. I know the function works fine, as the app connects and allows writing to the database.

            Now I am trying to test this function with Jest. To avoid testing outside the scope of this function, I am mocking the firebase-admin Node module. However, my test is failing with the error "TypeError: admin.firestore is not a function".

            My function and tests are both written in TypeScript, run via ts-jest, but I don't think this is a TypeScript error, as VS Code has no complaints. I believe this is an issue with Jest's automatic mocking.

            admin.firebase() is a valid call. The TypeScript definition file defines it as function firestore(app?: admin.app.App): admin.firestore.Firestore;

            I've read over the Jest docs, but I'm not understanding how to fix this.

            This is my function:

            Your code looks good. jest.mock mocks all the methods of the library and, by default, all of them will return undefined when called.

            Explanation

            The problem you are seeing is related to how the firebase-admin module methods are being defined.

            In the source code for firebase-admin package, the initializeApp method is being defined as a method in the FirebaseNamespace.prototype:

            Jest does not collect coverage from vue files (nuxt)
            Asked 2020-Feb-25 at 10:28

            When I run jest --coverage jest only collects coverage from JavaScript files, but not my vue files. The folder structure is correct. jest.config.js is in the root folder, just like /components and /lib. For me, there is no logical explanation why coverage is collected from JavaScript files but not from vue files.
