Using SoapUI with Selenium WebDriver: Complete Guide to Web Service Testing Automation Best 2025

👉Using SoapUI with Selenium for Web Service Testing

Using SoapUI with Selenium: As web applications increasingly rely on APIs and microservices, it’s essential to ensure both frontend and backend services work seamlessly. SoapUI and Selenium WebDriver are two powerful tools that, when combined, provide complete test coverage for both UI and API layers.

This tutorial explains how to integrate SoapUI with Selenium WebDriver using Groovy scripting, allowing you to run API and web UI tests together in a single flow.

👉 What is SOAP?

Using SoapUI with Seleniu: mSOAP (Simple Object Access Protocol) is an XML-based messaging protocol used to communicate between applications over HTTP. It relies on WSDL (Web Services Description Language) for defining the web services interface.

SOAP allows structured and standardized communication, making it ideal for enterprise applications that need reliability and security.

👉 What is SoapUI?

Using SoapUI with Selenium: SoapUI is an open-source, cross-platform API testing tool designed for SOAP and RESTful web services. It allows testers to:

• Create and run functional API tests
  
• Validate request/response structures
  
• Automate test flows using Groovy scripting
  

SoapUI Pro (commercial version) provides advanced features like data-driven testing and assertions.

👉 What is Selenium WebDriver?

Using SoapUI with Selenium: Selenium WebDriver is a popular browser automation tool that allows you to write test scripts for web applications using various programming languages such as Java, Python, or C#.

• It interacts directly with browsers using native commands.
  
• Enables test automation across multiple platforms and browsers.

 👉Why Integrate Selenium with SoapUI?

Using SoapUI with Selenium: By integrating SoapUI and Selenium, you can:

• Combine frontend (UI) and backend (API) tests in one test suite
  
• Validate data flow between UI inputs and backend responses
  
• Simulate real-world user workflows that involve API calls and UI interaction
  

---

 👉Prerequisites for Integration

Using SoapUI with Selenium: Before integrating Selenium with SoapUI, ensure the following are installed:

• Java SDK
  
• Groovy SDK (Groovy is fully supported in SoapUI and runs on JVM)
  
• Selenium WebDriver JARs
  
• SoapUI or SoapUI Pro
  

 Note: Groovy scripts can use any Java library directly, including Selenium.

👉 Running SoapUI Tests from Selenium

✅ Steps to Execute:

1. Open SoapUI
   
2. Create a new TestCase
   
3. Add a Groovy Script Step
   
4. Paste the Selenium integration code
   
5. Click ‘Play’ to execute
   

When executed, the script will:

• Launch a browser (e.g., Firefox)
  
• Navigate to a page (e.g., Google)
  
• Log results in SoapUI logs
  
• Pass dynamic parameters like city and zip code into the test case

👉 Code Example: Groovy Script in SoapUI

Using SoapUI with Selenium: Here’s a simplified example of how Selenium and SoapUI work together:

groovy

@Grab(group=’org.seleniumhq.selenium’, module=’selenium-firefox-driver’, version=’3.141.59′)

import org.openqa.selenium.WebDriver

import org.openqa.selenium.firefox.FirefoxDriver

def driver = new FirefoxDriver()

driver.get(“https://www.google.com”)

log.info “Opened Google in Firefox”

driver.quit()

You can enhance this by adding dynamic properties using:

groovy

testRunner.testCase.setPropertyValue(“city”, “New York”)

testRunner.testCase.setPropertyValue(“zip”, “10001”)

And retrieve them inside SoapUI test steps.

👉 View SoapUI Logs

SoapUI logs every test action, error, and response. To view the logs:

• Navigate to the installation directory
  
• Go to bin/soapui.log (e.g., C:\Program Files\SmartBear\SoapUI-Pro-4.0.1\bin)
  
• Open the file to review execution details and errors
