import * as (jasmine spyOn) not writable












2















After upgrading to babel 7.1.5 my tests fail when i'm using import * as.



test.spec.js



import * as Helper from "../../../../src/renderer/modules/Helper";

describe('Testing', () => {
it('Should import correctly', () => {
console.log(Helper.test()) // a
spyOn(Helper, 'test').and.returnValue('b');
});
});


Helper.js



function test() {
return 'a'
}

export {test}


ERROR



'Upgrade.spec.js (7:8)', 'a'

Error: <spyOn> : test is not declared writable or has no setter
Usage: spyOn(<object>, <methodName>)
at <Jasmine>
at UserContext.it (webpack:///./test/unit/specs/renderer/Upgrade.spec.js?:7:5)
at <Jasmine>

  • Im getting around this at the moment by using "@babel/plugin-transform-modules-commonjs" within .babelrc plugins just for my tests however this is not ideal.
