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'
      }
    }
  };
};
