DummyAPI Rest Assured Automation Test

Project Overview

This project demonstrates API automation testing using Java, Rest Assured, and JUnit 5 for the DummyAPI. It follows clean code principles and uses a simple pattern for API calls and reusable assertion helpers.

Tools, Frameworks & Versions

Tool/Framework	Version	Purpose
Java JDK	11+	Language/runtime
Maven	3.6+ (tested: 3.8/3.9)	Build, dependency management
Rest Assured	5.3.0	API automation framework
JUnit Jupiter (JUnit 5)	5.9.3	Test framework
Maven Surefire Plugin	3.0.0-M7	Test execution
JSON Path (Rest Assured)	5.3.0	JSON parsing in tests

Setup Instructions

1. Install Java (JDK 11 or newer)
   • Download OpenJDK or Oracle JDK.
   • Verify installation:

     java -version
     # Should show version 11 or newer

2. Install Maven (3.6 or newer recommended)
   • Download Maven.
   • Verify installation:

     mvn -version
     # Should show Maven version 3.6 or newer

3. Clone or copy this repository
   • Place all files in a directory, e.g. Java-API-Automation-Test-DummyAPI
4. (Optional) Update app-id
   • The tests use the app-id 6112dc7c3f812e0d9b6679dd (see DummyApiTests.java). If you have a different app-id, update the constant in the test class.

Test Run Output

Project Structure

• pom.xml — Maven configuration (dependencies: Rest Assured, JUnit 5)
• src/test/java/com/example/dummyapi/DummyApiTests.java — Main test class
• src/test/java/com/example/dummyapi/client/ApiClient.java — For API calls
• src/test/java/com/example/dummyapi/TestUtils.java — Reusable assertion helpers

Key Features

• Validates response status, data types, and paging
• Asserts all items in returned lists
• Negative test for missing app-id
• Clean code, reusable helpers, and simple design pattern

Troubleshooting

• If tests fail due to network issues, check your internet connection.
• If you get a 403/401 error, verify your app-id is correct and active.
• For Java/Maven errors, ensure both are installed and on your PATH.
