Karma: console log not working

[madroneropaulo]

Expected behaviour

I expect to be able to console.log() on any spec.

Actual behaviour

Logs are printed only within the "describe" scope, but not within blocks beforeEach, it, etc.
Instead, a TypeError is returned "undefined is not a constructor (evaluating 'console.log()'...)"

describe('Some spec', function() {
    console.log('it works!') // is logged
    it('Should do something',  function () {
        console.log('it does NOT work') // Type error. No logs. Spec is stopped (error thrown)
    })
})

Steps to reproduce the behaviour

1. Write some console.logs all over your specs (within describe blocks, it blocks, beforeEach, etc)
2. Run karma server
3. look into console

@madroneropaulo this

console.log('it doesn't work :( ')

is invalid javascript.

Try this in your test:

console.log('foo');

[madroneropaulo]

@maksimr Ok that was a random text comment, I have valid text on my specs. Please reopen. I updated the issue. I don't want to create a new one.

[maksimr]

@madroneropaulo can you create a stub project which reproduces this error?
Because I see nothing strange in your config.

Thanks

@madroneropaulo see https://github.com/karma-runner/karma/issues/2582

[leegee]

Looks like you are missing two things in your config: client.captureConsole = true and logLevel: config.LOG_LOG,. As @wbruno says, take a look at #2582 very carefully.

[EzraBrooks]

@wbruno and @leegee are correct, your issue should be solved by implementing the config changes described in the last comment on #2582.
