API Testing Mini-Project

A RestAssured test automation framework for testing the AutomationExercise API endpoints.

Project Overview

This project tests various API endpoints from automationexercise.com using RestAssured, JUnit, and POJOs for clean, maintainable test code.

Endpoints Tested

Endpoint	Method	Description
/api/productsList	GET	Retrieve all products
/api/productsList	POST	Invalid method test (negative scenario)
/api/brandsList	GET	Retrieve all brands
/api/searchProduct	POST	Search for products by keyword
/api/createAccount	POST	Register a new user account
/api/getUserDetailByEmail	GET	Fetch user details by email
/api/deleteAccount	DELETE	Delete a user account

Each endpoint has its own package containing:

• Test classes
• POJOs for request/response mapping
• Shared utilities (Config, RequestSpecBuilder)

How to Run Tests

Prerequisites

• Java 11 or higher
• Maven 3.6+

Running All Tests

mvn clean test

Running Specific Test Class

mvn test -Dtest=ListAllProductsTests

Running from IDE

Right-click on any test class or method and select "Run"

How to Add New Tests

1. Create a new package under src/test/java/com.sparta/ for your endpoint
2. Create POJO classes in a pojos subfolder to match the API response structure
3. Create your test class:

public class YourEndpointTest {
    private static Response response;
    
    @BeforeAll
    static void setup() {
        response = RestAssured
            .given()
                .baseUri(Config.getBaseUri())
                .basePath("/api")
                .contentType(ContentType.JSON)
                .accept(ContentType.JSON)
            .when()
                .get("/yourEndpoint")
            .then()
                .extract().response();
    }
    
    @Test
    void testStatusCode() {
        MatcherAssert.assertThat(response.statusCode(), Matchers.is(200));
    }
}

Technical Challenges & Solutions

HTML-Wrapped JSON Responses

The API returns JSON wrapped in HTML tags. Solution:

.expect().defaultParser(Parser.JSON)

Inconsistent Response Codes

The API returns HTTP 200 for all responses but includes error codes in the response body. Tests validate both:

assertThat(response.statusCode(), is(200));
assertThat(responseBody.getResponseCode(), is(405));

Form Data Submission

Some endpoints require multipart form data:

.contentType("multipart/form-data")
.multiPart("search_product", "tshirt")

Complex Nested JSON

POJOs handle deeply nested structures:

{
  "category": {
    "usertype": {
      "usertype": "Women"
    },
    "category": "Tops"
  }
}

Known Issues & Defects

1. Inconsistent HTTP Status Codes: API returns 200 OK for error scenarios instead of appropriate error codes (e.g., 405 for unsupported methods)
2. Irregular Product IDs: Gaps in the ID sequence and duplicate product names
3. Content-Type Mismatch: API returns text/html instead of application/json
4. Limited Documentation: Sparse API documentation required exploratory testing

Future Improvements

• Add more negative test scenarios (invalid data, boundary testing)
• Test for duplicate records across endpoints
• Combine related operations (e.g., create account → get details → delete)
• Implement data-driven testing with multiple test datasets
• Add API performance tests
• Generate test reports using Allure or Extent Reports

Git Workflow

This project follows a branching strategy:

• main - Production-ready code
• dev - Development branch
• feature/* - Individual feature branches

Configuration

Base URI and other settings are stored in config.properties:

base.uri=https://automationexercise.com
base.path=/api

Access via the Config utility class:

String baseUri = Config.getBaseUri();
