You have selected the Web service you want to test.
You know the location of the endpoint you want to test.
You know the user name and password for the endpoints that require authentication.
When you select the Web service you want to test, the system loads the corresponding WSDL file. This file contains information about the endpoints configured on the selected system. You can choose one of these endpoints to run the test. If you have the same service running on a different system, you can choose to test one of its endpoints. To do this, you need to provide the location of the endpoint.
When the selected endpoint requires basic HTTP authentication, you can enter the logon data in advance. You can also set the timeout for the test.
To use an endpoint described in the WSDL file, select Predefined and choose an endpoint from the list.
To use another endpoint, for example, one available on a different system, select Custom and enter the endpoint location.
You can obtain the endpoint location from the location attribute of the corresponding address tag in the service definition file. More information: Managing WSDL Documents
Choose None when there is no HTTP authentication required.
Choose HTTP Authentication when you need to use a user name and password to access the endpoint, and enter the required data.
In Web Services Navigator, you can test only Web service endpoints that require basic HTTP authentication (User ID/Password) or no authentication.
You can also use Web services that support Single Sign-On authentication, only if a WSDL with WS-Policies is used.
To test Web services protected with a different security mechanism, for example, X509 certificates, you can create a logical destination with the appropriate authentication and start the testing via that logical destination.
