[Bug]: Not able to access window in vm.runInContext about jest HOT 5 OPEN

You're trying to run vm inside of vm, which is not really supported. Why do you need to do that?

from jest.

when we are doing vm.createContext(global), we are not able to access window in the js files, even though we have injected window into context

from jest.

Im working on a legacy js project, we don't have export and import. so we are using vm.createcontext to inject some js files globally before all tests runs, especially some class.
Is there any better approach to do this.
Also what do you mean by vm inside vm ?

https://jestjs.io/docs/configuration#setupfiles-array should do what you want.

Jest already runs all tests within separate vm contexts

Still we need to inject the class and singletons to the global object right ?. since we don't have exports and imports
for example

var myVar = {};
myVar.getName = function(){
    return 'rahul mr'
}

it('hello this is my test', () => {
    console.log('hello', myVar.getName());
})

For this to work , we are required to run vm.runincontext() with global as context

from jest.
