01. SoapUI for Web Service Testing

Level: Intermediate

ℹ️ What You'll Learn

• Install and configure SoapUI
• Test SOAP web services
• Test REST APIs comprehensively
• Create automated test suites
• Load testing for performance
• Validate School Management System API

The Problem

Postman is great for manual testing. SoapUI is for automated, repeatable test suites. When your School Management System API has 20+ endpoints and you change something, you need tests that verify nothing broke. SoapUI automates this testing.

Install SoapUI

Download from: https://www.soapui.org/downloads/soapui/

Install and launch.

Create Project

File → New soapUI Project:

Name: SMS-API-Tests

Test REST API

1. Projects → Right-click → New REST Service
2. URL: http://localhost:5000/api/students/101
3. Method: GET
4. Click Send

Response appears in editor.

Test Requests

Get Student:

GET /api/students/101

Create Student:

POST /api/students
Content-Type: application/json

{
  "name": "Priya Sharma",
  "rollNumber": "SMS-2024-002",
  "className": "10-B"
}

Assertions

Right-click response → Add Assertion:

- Status: 200 OK
- Response contains: "Ravi Kumar"
- JSON path: $.name

Green ✓ = pass, Red ✗ = fail.

Test Suites

Create test workflow:

1. Get all students
2. Get specific student
3. Create student
4. Update student
5. Delete student

Run in sequence. Failure stops suite.

Load Testing

Tools → Load Testing:

• 10 concurrent users
• 100 requests per user
• Measure response time
• Identify bottlenecks

SMS API can handle production load?

Key Takeaways

• SoapUI = API testing (REST + SOAP)
• Requests + Assertions = tests
• Test Suites = workflow automation
• Load Testing = performance check
