Top 15 SOAP UI Interview Questions

1) Explain what is SOAP UI?

SOAP UI is a free, open source cross-platform functional testing solution. It enables you to

rapidly and easily create and execute automated regression, compliance, functional and load

tests.

2) Explain what is the role of XML, SOAP, WSDL and UDDI in web services?

Web services are a medium through which web based application can be integrated or

communicated over an internet protocol backbone. Web based application can be integrated

using XML, SOAP, UDDI and WSDL. SOAP is used for transmitting the data; WSDL is used for

describing or relating the services, UDDI is used for listing what services are accessible, XML is

used to tag the data.

3) Mention what SoapUI can do?

SoapUI can-

It can do automated testing like load tests, scenario-based tests and data driven tests

It has got built-in reporting abilities

It has got unique ability to impersonate web services and run functional and load test

against them even before they are executed

4) Mention how SoapUI is used to structure functional tests?

SOAP UI uses three levels to structure functional tests

TestSuite: It is a pool of test cases used for combining functional tests into logical units

TestCase: It is a group of test steps that are bring together to test some specific aspect

of your services. You can augment any number of testcases to test suites

TestSteps: They are “building blocks” of functional tests in SOAPUI. They together

makes TestCase and determines the flow of execution of the service to be tested

5) Mention what is the difference between REST and SOAP?

1 / 5

SOAP: Soap stands for Simple Object Access Protocol and it is a protocol used for

receiving and sending data over HTTP as XML

REST: It is a way of designing a web services.

6) Explain what is the properties in SoapUI?

Properties in SOAPUI is used to retrieve and store data. The data is stored as key, value or

format.

7) Explain where you use properties in SoapUI?

We can read the property values into test step endpoint, username, header values, password,

domain, POST, PUT, GET and DELETE method properties.

8) Mention what languages does SoapUI use?

SOAP UI supports two language, Groovy, and JavaScript.

9) Mention what are the default properties in SOAPUI?

By default, SOAPUI has properties at three levels

Project level default or custom properties: User can append any number of

properties at project level and it can be opened from any test steps from any test cases

under any test suites

Test suite level default or custom properties: User can append any number

properties at test suite level and it can be used from any test steps from any test cases

under this test suite

Test case level default or custom properties: At test case level users can add any

number properties at test case level and it can be used from any test steps from this test

case

10) Explain how you can parameterize the endpoints in SOAP UI?

To parameterize the endpoints in SOAP UI is most important as it is the first step in automation

testing. It is more time consuming for changing endpoints manually. In order to do that

Define a project property holding the endpoint

Change the endpoint to use this property via property expansion

Ensure that your requests are availing the configured endpoint

When a request is run, the property will inevitably be with its current value. To use a

different value just configure the endpoint in the UI, you can use the P option from the

command line

11) Mention what is the general format for reading the custom or default property value?

The general format for reading the custom or default property value is ${#levelname#key}

12) Inside the SOAPUI where groovy script can be used?

Inside the SOAPUI groovy script can be used in two places

Groovy script test step

Script Assertion- within test step

13) Mention some important functionalities of SOAP UI?

Some important functionalities of SOAP UI are:

It creates a new project using only the web service WSDL link; it will get the information

of all methods and import them automatically

It creates test cases directly from the web method request

It tests web methods in combination or separately. It has a very useful capability which

allows datas and parameters to be passed from one method to another. It enables you

to save data in variables so other methods can access it

It enables creating validations on the web method results through assertions; the

assertion can be created either in X-path or X-query

It helps in creating other types of validations like schema compliance, soap fault,

response time etc.

It enables organizing the test cases in test suites

It enables running all test cases from a test suite and getting fail/pass results for each

test case

It enables parameterization of the test cases request fields so that a test case can avail

different values from a table or database

Using groovy it enables creating complex validation scripts

It has some support for web service load testing

It has some support for testing coverage and requirements management

14) Explain what assertion is in Soap UI is and give some example of assertion possible

in SOAPUI?

In SOAP UI assertion functionality is used to validate the response of request received by the

Test Steps at the time of execution. It is used to compare a part of message to some expected

value.

15) Does SoapUI support SSL Authentication

Yes
