Использование службы WCF в Postman на основе ClientBase

Question

Я хочу протестировать WCF на основе класса ClientBase в почтальоне, как мне это сделать?

Адрес конечной точки = "http://xxxxxxxx/xxxxx/TestService.svc" и bindingConfiguration="BasicHttpBinding_TESTAPI "

Реализация службыкак показано ниже:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]    [System.ServiceModel.ServiceContractAttribute(ConfigurationName="TESTFApi.TESTAPI")]
public interface TESTAPI {
    [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/TESTAPI/TESTReceiver", ReplyAction="http://tempuri.org/TESTAPI/TESTReceiverResponse")]
    string TESTReceiver(string xRequest);
}

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
public interface TESTAPIChannel : TESTAPI, System.ServiceModel.IClientChannel {
} 

public partial class TESTIClient : System.ServiceModel.ClientBase<TESTAPI>, TESTAPI {

    public TESTAPIClient() {
    }

    public TESTAPIClient(string endpointConfigurationName) : 
            base(endpointConfigurationName) {
    }

    public TESTAPIClient(string endpointConfigurationName, string remoteAddress) : 
            base(endpointConfigurationName, remoteAddress) {
    }

    public TESTAPIClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) : 
            base(endpointConfigurationName, remoteAddress) {
    }

    public TESTAPIClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) : 
            base(binding, remoteAddress) {
    }

    public string TESTReceiver(string xRequest) {
        return base.Channel.TESTReceiver(xRequest);
    }
}

Я хочу смоделировать вызов в Почтальоне на TESTReceiver (xRequest)
