As an IT consultant specializing in software testing and services for the past 5 years, I have extensive experience using SOAPUI across various client projects for API testing.

In this comprehensive tutorial, I will provide a step-by-step visual guide to download, install, and optimize the configuration of SOAPUI on a Windows machine.

A. Downloading SOAPUI

Before installing SOAPUI, ensure your Windows PC meets the minimum system requirements:

System Requirements:

  • Windows 10, 8 or 7
  • 64-bit Intel processor
  • 4 GB RAM
  • 1 GB disk space

To download SOAPUI:

  1. Open your web browser and go to the official SOAPUI download page at https://www.soapui.org/downloads/latest-release/

  2. Scroll down to find the installer for Windows. If your machine is 64-bit, select the 64-bit installer file:

  1. Clicking the download button will trigger the SOAPUI installer to begin downloading immediately.

Pro Tip: Click the download with your mouse instead of CTRL+clicking. This ensures the installer .exe runs automatically after downloading instead of saving the file to your computer first.

  1. After a minute or two, you should receive a notification that the SOAPUI download is complete. At this point, the .exe installer file should run automatically. If it does not launch, navigate to your downloads folder and double click the file manually.

B. Installing SOAPUI

With the installer download complete, you‘re ready to install SOAPUI onto your Windows machine:

  1. If the SOAPUI installer file did not run automatically, double click it now in your downloads folder to launch.

  2. You may receive a Windows security prompt asking for permission to run the installer executable. Check ‘Always trust software from SmartBear Software‘ and click Yes to allow the installer to launch.

  3. This will trigger the SOAPUI Setup Wizard to begin the installation process:

  1. Click Next on the Welcome page to continue to the License Agreement. Read the agreement and select ‘I accept the agreement‘ before proceeding to the next step.

  2. On the Choose Install Location page, you can leave the default Program Files folder, or click Browse to select an alternative folder destination for the SOAPUI program files.

  3. Next, select the components to install on the Custom Setup page:

- **SOAPUI** - Required for API testing functionality- **SOAPUI Source** - Enable to access source code- **HERMES JMS** - Add-on for JMS protocol testing- **Tutorials** - Help documentation for learning SOAPUI
  1. Click Next and SOAPUI will begin installing the components onto your Windows computer.

Installation Tips

  • Disable antivirus – Temporarily disable any antivirus software to prevent potential conflicts blocking files from installing.

  • Enable auto-updates – On the final page, check the box to enable automatic updates to get notifications whenever new versions of SOAPUI are released.

After a minute or two, SOAPUI should finish the install process and launch automatically with a Welcome screen.

C. Configuring Your SOAPUI Workspace

Before creating your first API testing project, it is important to setup your preferences and customize your SOAPUI workspace.

1. Set User Preferences

From File > Preferences, you can configure options that control how SOAPUI operates globally across all your API testing projects.

Here are some key preferences to set or modify:

HTTP Settings

Control request timeouts, SSL security protocols, compression, and HTTP client versions used across your projects.

UI Settings

Customize interface behavior like default tab layouts, auto-save frequency, backups, and project loading.

Assertions

Standardize error checking and validations across tests to keep testing consistent.

2. Create Your First SOAP Project

With preferences set, create your first API testing project:

  1. Go to File > New SOAP/REST Project > New SOAP Project.

  2. When prompted, give your project a name like ‘MyStore Testing‘.

  3. Click OK and a new project titled ‘MyStore Testing‘ will appear in the Navigator pane.

At this point you have a blank project started to begin adding API test cases and test suites to execute requests against your target web service APIs!

Recommended Next Steps

Now that SOAPUI is downloaded, installed, and configured – here are my top recommendations as next steps:

  1. Create a sample project following my guide on How to Test a SOAP API in SOAPUI from Scratch

  2. Take the free SOAPUI interface tutorial to learn core functionality faster.

  3. Enable cross-browser testing and load testing by upgrading to SOAPUI Pro.

Let me know in the comments if you have any other questions on optimizing your SOAPUI instance! I‘m happy to provide installation support and API testing best practices.
