Type Error with `const`

I face myself against a Type Error when trying to rewire a private const I already have the last version 4.0.1

I used the workaround using let but I would prefer to use const as I don’t want to change my code only for test purposes

Demo: index.js:

const myPromisifiedFunction = promisify(someFunct.ToPromisify) index.test.js:

const myModule = rewire(‘…/myModule’) const myStub = sinon.stub() const revert = myModule.set(‘myPromisifiedFunction’, myStub) And what I get when running tests is: TypeError: Assignment to constant variable. at eval (eval at set (index.js:159:5), <anonymous>:1:19) at Object.set (index.js:159:5) at Object.<anonymous> (test/index.test.js:14:48)

Thanks in advance for any help you could provide !

Edit: I’m aware of the #79 issue, I already commented on it but since it’s closed I thought it would be better to open a new one

I’d like to provide some additional evidence. The issue appears to happen when using the Jest testing library but not with Mocha. I created a git repo to show the issue: https://github.com/Shakakai/jest-rewire-const-error

Here’s a link to the issue in Jest: https://github.com/facebook/jest/issues/6803 I’m not sure which library is responsible.

I’m having the same problem, also using Jest!
