jest branch coverage seems to have a problem with if statement recognition?
Jest Config: module.exports = { setupFiles: [], clearMocks: true, collectCoverage: true, testEnvironment: ‘jsdom’, transform: { ‘^.+.tsx?$’: [‘ts-jest’, { diagnostics: false, babelConfig: true }], ‘^.+.js$’: ‘babel-jest’, ‘node_modules/vue-runtime-helpers/.+.mjs$’: ‘babel-jest’, ‘..(vue)$’: ‘@vue/vue2-jest’ }, roots: [‘/tests’], testMatch: [‘**/.test.ts’], coverageThreshold: { global: { branches: 80, functions: 80, lines: 80, statements: 80 } }, // 1:解决Jest: a transform must export a […]

Using the Spy in Jest on a ProductLookupClient in the test class always returns undefined
I created a service which returns a list of products given the productId. However, when I mock the value to be returned by the ProductLookupClient it always returns undefined in my test class using the debugger. I create an instance of the class and use it in a jest.spyOn.
Error with import/mock in Jest test for functions in a module where one is a dependency in the other
I’m new to Jest, so I’m still trying to wrap my head around everything, but I’m having issues when it comes to tests for functions in a module when one of the functions is being called in another. I’ve managed to write tests fine with mocks when the functions are separated into their own files/modules, but it seems more complicated when they belong to the same module.
Jest.mock() in another file
I have a CRA-rewired typescript react app.
