#JEST MOCKS MANUAL#
Set up mocks at the top because of how server.js sets up k8s clientĬonst k8sClient = require('kubernetes-client') Ĭonst namespaces = jest.fn(). I agree with MattyKuzyk that it seems counterintuitive that a module under test wouldn't use a manual mock defined for a dependency when the test explicitly says to jest.mock that module. In my testing environment, I don't want any API calls, so I'm trying to mock it out: // _tests_/ There are 18 other projects in the npm registry using jest-mock-axios. For that, we just need to add the following line to the.
Start using jest-mock-axios in your project by running npm i jest-mock-axios. We need to instruct Jest to use the mocked Http class when running the test for the Users class. Note that we are testing GET request, so we use axios.get for mocking the response. Latest version: 4.6.1, last published: 3 months ago. Create a sample response and make mocked axios instance return it: (users). The project uses the "kubernetes-client" library from godaddy and tries to create a config object from the envvar "KUBECONFIG", like this: // a few lines into server.jsĬonst Client = require('kubernetes-client').ClientĬonst config = require('kubernetes-client').config Ĭonfig: omKubeconfig(config.loadKubeconfig()),Ĭlient = new Client() The easiest and the most popular way to mock Axios in Jest is to use the jest.mock () function: Mock Axios: jest.mock ('axios'). expect (method1 ()). This helps Jest correctly mock an ES6 module that uses a default export. However, I cannot get mocks to work like I'd expect in, say, python. In order to successfully mock a module with a default export, we need to return an object that contains a property for esModule: true and then a property for the default export. I'm trying to introduce a small change to an existing project without unit tests and decided I'd try to learn enough about nodejs and jest to include tests with my change.
