Google Chrome (headless)

When running tests in browser, wallaby.js uses your local version of Google Chrome (headless) as its test runner by default.

You may use an absolute or a relative path (or a command if you have it in PATH) in your wallaby.js config file. It may be useful if you would like to use a specific version of Chrome.

wallaby.js

module.exports = function () {
  return {
    ...

    env: {
      kind: 'chrome',
      runner: '/Users/user/path/to/chrome'
    }
  };
};

Passing Chrome flags

By default, wallaby.js is passing the following flags to Chrome:

--headless
--disable-gpu
--disable-translate
--disable-extensions
--disable-background-networking
--safebrowsing-disable-auto-update
--disable-sync
--metrics-recording-only
--disable-default-apps
--no-first-run

For Linux environments, an additional two flags are also passed:

--no-sandbox
--disable-setuid-sandbox

You may pass other flags, by using the env.params.runner setting, for example:

wallaby.js

module.exports = function () {
  return {
    ...

    env: {
      kind: 'chrome',
      params: {
        runner: '--headless --disable-gpu'
      }
    }
  };
};
