Web Services

Web Services?

Web services are mainly used to communicate between different kind of web site and server.Web services are mainly based on XML, SOAP. Web services are application components. Web services communicate using open protocols. Web services are self-contained and self-describing. Web services can be discovered using UDDI. Web services can be used by other applications.

Functional Tests of Web Services

Introduction Let's move on and look at how tests work in SoapUI. We have created three different TestSuites all containing different TestCases. A TestCase is made up of several steps, called TestSteps. The structure of a SoapUI project is like this; Project Interface TestSuites TestCases TestSteps LoadTests MockServices As you can see there is also something called LoadTests, we can gather what they are, but we'll go into detail more what they actually do and how they actually work later. Tutorial Now let's examine a Functional Test in a TestCase. Expand the Sample Simple TestSuite and double click on Simple Login and Logout w. Properties Steps. As you can see the TestCase consist of five TestSteps. You can also click the Description tab in order to see the in test documentation. The step consists of three different types of TestSteps; One PropertyStep, Two TestRequests and TwoPropertyTransfer Steps. This is what they do: PropertySteps: Stores Properties for later use. In our case it's the Username and Password required to login. Test Requests: The actual requests to the server. In this case login and logout. PropertyTransfers: A step used for moving properties between different steps. This might be from a Property Step to a request like the step Property Transfer: Move Username and Password does, or to move properties from a Test Request to another, like the step Property Transfer: Move sessionID does. Double click on the TestStep Property Transfer: Move Username and Password. The TestStep Editor will now open on the SoapUI desktop. Concept: this property transfer does two transfers in two Properties. First it takes does the TransferUser Transfer. It takes the Property Username from the step Properties: Username and Password and moves it to the step Test Request: login. Then it takes does the TransferPass Transfer. It takes the Property Password from the said stepProperties: Username and Password and also moves it to the step Test Request: login. An important feature in SoapUI Tests is The Assertions. Assertions are made in Test Requests and is for validating that the response is what we expected. Open the Test Step Test Request: logout. In the TestStep we have four assertions, asserting different things; SOAP Response That the response is a SOAP response Schema Compliance That it complies with the Schema Not SOAP Fault That is isn't a SOAP fault XPATH Match And something called an XPATH match. The XPath Match validates that a certain element has the value expected.
