onGet and other methods is not defined about axios-mock-adapter

[mustaphaturhan]

Looks like changing moduleNameMapper from axios to ^axios$ makes it work:

  moduleNameMapper: {
    '^axios$': 'axios/dist/node/axios.cjs',
  }

Facing same issue. Does anyone had that and fixed it or do I need to replace library for mocking axios?

[KonradFak]

I've manage to fix it in my case by bumping versions of jest and ts-jest. My current versions are:

• axios 1.5.0
• axios-mock-adapter 1.21.5
• jest 29.7.0
• ts-jest 29.1.1

Thanks @marcbachmann for pointing out the right direction 😄

I created test repo with example https://github.com/Shub1nk/test-jest-and-axios-mock-adapter

I use jest@29, [email protected] and [email protected] and it work. But if I enable these options in jest's config, I will get error that mock.onGet is not function (mock -> Promise) again.

// ATTENTION: Test with axios mock fails if I enable these options
transformIgnorePatterns: ['/node_modules/(?!axios)'],
moduleNameMapper: {
axios: '<rootDir>/node_modules/axios/dist/node/axios.cjs',
 },

I found out when I run mock in Storybook then all work. I made example with mocking inside this library and this example work too.

But, when I run Jest when I use axios-mock-adapter inside tests then new MockAdapter begin to return Promise and I get error mock.onGet is not a function.

I don't understand what is going on.

Must be Jest specific. I have axios 1.5 working with axios-mock-adapter

[Shub1nk]

@marcbachmann Can you share your Jest config?

I have next settings in Jest for axios:

transformIgnorePatterns: ['/node_modules/(?!axios)'],
    moduleNameMapper: {
        axios: '<rootDir>/node_modules/axios/dist/node/axios.cjs',
    },

People from other releases write that jest, axios and axios-mock-adapter work for them with these settings. For some reason it doesn't work for me

[marcbachmann]

sorry, not using jest. that's why it must be jest specific 😅

[Shub1nk]

it works with axios 0.27.2. When I was updated axios to 1.5 it broke

Multiple libraries are affected due to axios, I tried with msw, nock and this one none of them is working properly [email protected]
