return expression of async function is not showing coverage #16

Closed tikotzky closed 9 years ago

tikotzky commented 9 years ago

if you test the following code...

async function foo(){
    return 'foo';
}

(async () => {
    let result = await foo();
    console.log(result);
})();

the coverage comes out looking like index js 2015-06-21 21-15-34

It works for me now after #15. However, the console.log after the await is not called for me (I don’t see the log when i run it with babel-istanbul cover)

jeffrifwald commented 9 years ago

@Swatinem What are you using to actually run the tests? You might be exiting before the log statement is hit.

Swatinem commented 9 years ago

just babel-istanbul cover --babel-stage 1 --use-babel-runtime test.js with the code pasted in. So yes, I do think that it exits before the log (or even before returning from the await)

tikotzky commented 9 years ago

@Swatinem do you get the log in your console?

tikotzky commented 9 years ago

just ran it again and it looks good now.
