   Following the browser specification are the username and access key used to identify your account with the cloud provider.
   The example uses two environment variables to access this information.
  
positive.code:        accessKey = System.getenv(LambdaTestAccount.ACCESS_KEY_ENV_VAR)
      }
      tunnelOps {
          additionalOptions = ['--proxy', 'proxy.example.com:8080'] //<8>
      }

  == Gradle plugins
  
  For SauceLabs, BrowserStack and LambdaTest, Geb provides a Gradle plugin which simplifies declaring the account and browsers that are desired, as well as configuring a tunnel to allow the cloud provider to
  access local applications.
  These plugins allow easily creating multiple `Test` tasks that will have the appropriate `geb.PROVIDER.browser` property set (where _PROVIDER_ is either `saucelabs`, `browserstack` or `lambdatest`).
  The value of that property can be then passed in configuration file to <<sauce-labs-driver-factory>>/<<browser-stack-driver-factory>>/<<lambda-test-driver-factory>> as the ”browser specification“.
  Examples of typical usage are included below.
