 * The step executes a closure (see example below) connecting to a sidecar container with a Selenium Server.
 *
 * When executing in a

 * * local Docker environment, please make sure to set Selenium host to **`selenium`** in your tests.
 * * Kubernetes environment, plese make sure to set Seleniums host to **`localhost`** in your tests.
 *
 * !!! note "Proxy Environments"
 *     If work in an environment containing a proxy, please make sure that `localhost`/`selenium` is added to your proxy exclusion list, e.g. via environment variable `NO_PROXY` & `no_proxy`. You can pass those via parameters `dockerEnvVars` and `sidecarEnvVars` directly to the containers if required.
