Hi there! I've added the

browser

as a target for my MPP project and I'm getting this error:

04 03 2020 16:26:34.829:ERROR [launcher]: No binary for ChromeHeadless browser on your platform.

  Please, set "CHROME_BIN" env variable.

What can I do to fix this? I tried to add chrome as the docs states:

browser {
    testTask {
        useKarma {
            useChrome()
        }
    }
}

but I get the same error. How can I make my builds run out of the box (without having to set env variables)?

If you don't use browser tests, you can disable them with

browser { testTask { enabled = false } }

. That way, the browser task shouldn't look for a browser binary.

thanks 👍

If you are actually running karma tests though, that's not what you want, but there are a bunch of other pre-configured browsers, according to: https://kotlinlang.org/docs/reference/js-project-setup.html#configuring-test-task

It worked!

You need Chrome by default to run tests, you need change browser with

useFirefox

for example Or even you can try to use

useMocha()

instead of

useKarma

how would this work in a CI environment?

Mocha will be executed in node environment, karma - is in browser, so browser should be installed in your ci environment

what if that's not an option?

On CircleCI you can easily run your pipelines in custom Docker containers with Chromium headless installed. There are hundreds of Docker images on Docker Hub for this exact scenario.

oh, that's nice

If you need Docker-in-Docker, ie build Docker images in a pipeline, you might want to use one of CircleCI's pre-configured images though.

not right now, but I'll take a look into it if the need arises

If so,

circleci/node:latest-browsers

might be a good fit. It has Firefox and Chrome installed (and node+npm, of course).
