SoapUI Tutorial for Beginners

What is SoapUI?

SOAP is the acronym for Simple Object Access Protocol. SoapUI is the world's most widely-used automation testing tool for soap and REST APIs. It's a lightweight protocol used for information exchange in a decentralized and distributed environment. You can do functional, load, security and compliance tests on your API using SoapUI. 

It was developed by Eviware in 2005 and later acquired by Smartbear in 2011. It's a cross-platform desktop-based application that can run on any operating system.

Why use SoapUI?

SOAPUI allows testers to execute automated functional, compliance, regression, load tests, and more on different Web APP. Let's discuss the essential features of SoapUI:

#1. Functional Testing 

A powerful tool that allows testers to write functional API tests.

• Provides user-defined scripts that can be customized as per user requirement.
• Supports drag and drop feature to create and run complex test scenarios.
• Supports multi-environment to switch between QA, Dev and Prod Environments.
• Allows advanced scripting

#2. Security Testing

Security testing plays an essential role in the authentication and authorization of web services and APIs. 

• Performs complete vulnerability scan to protect the services.
• Avoids SQL injection to secure the databases.
• Scans and locates the huge documents within XML messages that cause stack overflows.
• Scans for cross-site scripting, when specific parameters in structured messages are exposed.
• Performs boundary scan and fuzzing scan to avoid erratic behaviour of services. 

#3. Load Testing

In SoapUI, you can create advanced load tests easily on the base of existing functional API tests.

• Distributed load tests across any number of loadUI agents 
• Allows advanced custom reposting to capture performance parameters.
• Supports end-to-end system performance monitoring

#4. Compliance Testing

Compliance testing includes source and data authentication license certificate and various service agreements for web service validation.

#5. Regression Testing

In SoapUI, regression testing is used to analyze bugs and malfunctions of the web services. In the current release tools, it reverifies the new changes of the web services.

#6. SoapUI supported Protocols and Technologies.

SoapUI supports the following protocols:

• SOAP – Simple Object Access Protocol
• REST – Representational State Transfer
• WSDL – Web Service Definition Language
• AMF – Action Message Format
• HTTPS – HyperText Transmission Protocol Secured
• JDBC – Java Database Connectivity
• HTTP – HyperText Transmission Protocol
• JMS – Java Messaging Service

#7. SoapUI Integration with other tools

SoapUI integrated very well with popular tools:

• Apache Maven Project is a project management tool that manages a project's build, reporting and documentation from a central repository.
• HUDSON is a Java-based tool integrated with SoapUI to find bugs quickly. 
• JUnit is a unit testing framework built in Java that controls the flow of tests from SOAPUI
• Apache - Ant is used to develop projects and run test suites using the command line in SoapUI Tools. 

Next up, in this SoapUI Tutorial we will focus on SoapUI Architecture.

SoapUI Architecture

The following image shows the architecture of SoapUI:

Let's discuss the architecture of SoapUI in-detail:

• Test config files: These are the files that provide configurations related to testing data, expected results, data connection, variables, and any other environment setup or test specific details.
• Third-party API: They help in creating an optimized test automation framework. For example, the JExcel API allows integrating with MS Excel to create a data-driven framework.
• Selenium: These are the Selenium Jars that use UI automation.
• SoapUI Runner: It runs on the SoapUI project and is a handy utility for test automation as it supports you to run the test from the command line. Moreover, it acts as a trigger for test automation.
• Properties: These are the test requested properties that contain any dynamically generated data. 
• Groovy: This library enables SoapUI to provide its users with groovy as a scripting language.
• Test Report: SoapUI supports a Junit style report and uses Jasper reporting utility to report test results.

Now in SoapUI Tutorial, we’ll learn about SoapUI Versions.

SoapUI Versions

Frequently asked SoapUI Interview Questions

SoapUI Assertions

Assertions are the validation rules used to claim verification results and check whether the targeted web services work as expected. Assertions validate the messages received by TestStep during execution. SoapUI supports a wide range of assertions in response.

Following are the list of assertions supported by SoapUI:

SoapUI Properties

The term properties represent the characteristics of a specific object. They are a central aspect of more advanced testing with SoapUI. 

SoapUI properties provide the ability to hold authentication details, making it easy to manage them in a central place of external files.

Types of SoapUI properties:

1. Default Properties: These are the properties built in the SoapUI tool, or we can say when a new project is created in a SoapUI. 
2. Custom / User Defined Properties: These are the properties defined at any project creation point like a global, test case, test steps, etc. 

Defining Properties

We can define SoapUI properties at multiple levels in a project:

• Workspace Default Properties

For Workspace Default properties, select the Workspace in the Projects Navigator as shown below:

• Project Default Properties

Select a Project in the Projects Navigator to create a project default properties.

• Service Default Properties

Like mentioned above, select a Web Service in the Project Navigator to define service default properties.

• Operation Properties

Select an Operation property of the Project to define the default properties of the operation.

• Request Default Properties

Select a Web Request from the Operation Properties to define a Request Default property.

• Global Properties in SoapUI

The global properties are used to define globally associated properties in the SoapUI tool. To define a global property, follow the steps shown below:

1. First, click on the Preferences tab presented in the toolbar

2. The below image appears after clicking on the preferences tab.
