Soapui Interview Questions

  • What do you understand by the term WSDL? WSDL is an XML document and stands for Web Service Description Language. It provides information about web services and web methods. Web service origin, port types, response data, reports, and headers define the document’s service layer.

  • What do you think is the main challenge in web service testing? I believe the absence of a UI or User interface is one of the major web service testing problems. This is because functional testing is usually done using the GUI or Graphical User Interface.

  • What do you mean by a web service? Web components or software accessible over the Internet relaying data from the client to the server are called web services. The client sends web requests to the server and the server, in turn, relays a response to the client via XML messaging concepts. A particular request will always elicit a corresponding response. For instance, a particular site can be accessed by typing an appropriate web service URL.

  • List the advantages of SoapUI. SoapUI is XML-based, making it independent of programming language and platform. Soap overcomes RPCs (Remote Procedure Calls) that are prevented by proxy servers and firewalls.

  • What is SoapUI’s Xpath Assertion? Xpath gives a definite path to test the response of the web service. If the response corresponds to the path, the case is considered PASSED and vice versa. The Assertion tab at the end of the screen outlines the outcomes of the assertion.

  • List the different web service communication channels. Channels are mediums through which web services can communicate to clients. HTTP/POST protocol is a secure way of transferring messages between clients. HTTP/GET protocol shows the transferred data on the address bar, allowing clients to view the transferred data. Confidential data is safely transferred by SOAP.

  • What can SoapUI do? Automation testing, including load testing, functional testing, and data-driven testing, is offered by SoapUI. One can also report build versions, make logs, and export test results.

  • Explain data-driven testing. The input and corresponding expected output from the test data is stored in an XML/Excel/Database file. New iterations of the data source are made using respective components. Datasource loop and Datasource are the test steps for data-driven testing in SoapUI.

  • Elaborate about the Soap protocol message format. The XML language is used to write Soap based web services. The XML language format is easy to understand, identify errors and read.

An example of a Soap message is as follows.

<?xml version=”1.011”>

<soap:Envelope xmlns:soap=”http://www.abcde.com/soap-envelope”>

<soap:Header>

</soap:Header>

<soap:Body>

<m:TutorialName>ABC</m:TutorialName>

</soap:Body>

</soap:Envelope>

  • Enlist the different SoapUI assertion types.

    • XPath match
    • WS security Status
    • WS-Response assertion or Addressing Request
    • Soap Faults
    • XQuery match
    • Contains and Not Contains
    • Response SLA
    • Script Assertion
    • Schema compliance

  • Enlist the properties available in SoapUI. Properties exist at different levels in SoapUI. They are:

    • Test case level properties: Test data can be stored in test cases by creating their own properties inside the test case. They can be accessed from within test cases accordingly.
    • Project level properties or custom properties: These properties can be added multiple times based on the tester’s needs and can be utilized at test cases, test suites, and test steps whenever required.
    • Test suite level properties: Test suites can have custom properties and relevant information added by the tester. These properties are retrieved from the corresponding test suite only.

  • Explain what Groovy script is and its usage. The groovy script helps testers add custom validations and customize their SoapUI test. It is a Java library-dependent scripting language. It is commonly used at the Step Assertion Test Step and the Groovy Script Test step below the test case.

  • How would you validate your response? Assertions can aid data validation.
    • For example, the format for date of birth could be DD/MM/YYYY. Assertions can supplement regular expressions:
    • Groovy scripts connect to the database to retrieve data.
    • The data is then compared to the response XML.

  • What factors would you consider while deciding the style of web service being used? A web service based on REST is used to achieve scalability, simplicity support for numerous data formats, and performance. On the other hand, a soap-based service is used when optimizing for transactional reliability and extensive overall support. In other words, a decision regarding the web-service platform can be reached by asking the following questions.

    • What does the web service expose? Business logic or data? If the web service exposes logic, Soap is a better style, whereas if exposing data is the intention, REST is a better alternative.
    • Is a formal contract required? Soap through WSDL has a formal contract.
    • Is support from numerous data formats required? Do AJAX calls need to be made? REST uses XMLHttp request.
    • Are the calls asynchronous or synchronous, stateless, or stateful? Stateless CRUD operations involve REST.
    • What is the required level of security? Soap WS better supports security.
    • What is the required level of transaction support? Soap WS better supports transaction management.
    • Is the bandwidth-limited? Soap uses a greater number of words.
    • Which service is a better pick for developers looking to build clients using the service? REST is better service in terms of maintenance, implementation, and testing.

  • How does one make a Mock Sercive using Soap?

    • Select ‘Generate Mock Service’ after right-clicking on one of the Soap interfaces.
    • Specify the local path/port for the service you intend to create in the Giant Mock Service dialog and click OK.
    • In the Name dialog box, enter a name for the Mock service you just created and click OK.
    • After following these steps, a Mock Service with one operation and request should be created.

  • List any five HTTP status messages/codes.

    • 400 Bad Request. This indicates that the request was not formed properly. PUT and POST request a common occurrence when the data has not cleared validation or has the wrong format.
    • 404 Not Found. The clear indication of this request is that the source is untraceable. Requests pointing to a URL with no resource usually show this error message.
    • 409 Conflicts. This code indicates a conflict of action. A PUT request generated twice for the same resource shows this code.
    • 500 Internal Server Errors. Circumstances that were not anticipated on the server-side usually generate a 500 response code.
    • 200 OK. This response code indicates that a request was successful.

  • How would you parameterize the endpoint using SoapUI? The test step initiation process begins with automating the test cases. This, in turn, involves the parameterizing feature. To parameterize an endpoint, follow these steps.
    • Do a project with information about the endpoint.
    • If necessary, use the property expansion test step to change the endpoint or assign a property.
    • Make sure the endpoint address has the request information.
    • A property will hold a test value during execution. An IDE can easily provide a different input value to the property.

  • How would one automate the web services in SoapUI?

    • First, one needs to create a file, and next, add the WSDL file.
    • Later the addition of test suites and test cases is necessary. Test cases should always be added after test suites only.
    • Add Groovy steps to include validation or custom programming.
    • Always call external data sources if using them.
    • Add the necessary assertions.
    • Run the file.

  • Enlist how a test suite can be imported in SoapUI.

    • After clicking on the File menu, click on import preferences. Next, click Import SoapUI settings from another setting and further click file.
    • Click on the File Menu and select Import Project. This adds a pre-existing project to the workspace.
    • Click on the File Menu and select Import Remote Project. This imports a remote project into the workspace.
    • Click on the Icons Toolbar and select Import. This option imports a pre-existing SoapUI project into the workspace.

  • Is SSL Authentication supported by SoapUI? Yes, SSL Authentication is supported by SoapUI.

That brings us to the end of a few SoapUI interview questions as promised. One should also keep in mind that the interviewers are looking for subject expertise to shine through and gauge communication, clarity, project planning, and other non-subject expertise depending on the role being advertised.
