Not possible to use K8s service with a port for Grafana

[ernesgonzalez33]

If using the Kubernetes Service instead of the Ingress URL for the GRAFANA_URL variable, the test fails since it looks for the URL to resemble ${GRAFANA_URL}/login but in selenium, it would not include the port so it would be expecting the port to show.

This is the part of the code where this could be fixed:

marinera-e2e/src/test/java/org/fiware/marinerae2e/StepDefinitions.java

Lines 139 to 143 in 8220873

	@When("A user opens Grafana.")
	public void verify_forward_to_login_page() {
	webDriver.get(grafanaUrl);
	assertEquals(String.format("%s/login", grafanaUrl), webDriver.getCurrentUrl(), "The user should be forwarded to the login-page.");
	}
