API Testing Using Selenium Java

API testing using Selenium in Java involves using Selenium WebDriver to automate interactions with a web application’s user interface and perform various actions like clicking buttons, filling out forms, and verifying the results. However, it’s essential to note that Selenium is primarily used for UI testing, not API testing.

For API testing in Java, you might want to consider using libraries such as RestAssured or HttpClient to make HTTP requests to the API endpoints, send requests, and validate responses.

Here’s a basic example of API testing using RestAssured in Java:

First, you’ll need to include the RestAssured dependency in your project’s build file (e.g., Maven or Gradle).

Maven Dependency:

xml

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>4.4.0</version> <!-- Use the latest version available -->
</dependency>

Write a test case to perform an API request and validate the response:

java

import io.restassured.RestAssured;
import io.restassured.response.Response;
import org.junit.jupiter.api.Test;

import static io.restassured.RestAssured.given;
import static org.junit.jupiter.api.Assertions.assertEquals;

public class ApiTest {

    @Test
    public void testApiRequest() {
        // Set the base URL of the API
        RestAssured.baseURI = "https://api.example.com";

        // Send a GET request to a specific endpoint
        Response response = given()
            .when()
            .get("/endpoint");

        // Verify the response status code (e.g., 200 for success)
        assertEquals(200, response.getStatusCode());

        // You can also validate the response body and headers as needed
        // For example:
        // assertEquals("application/json; charset=utf-8", response.getContentType());
        // assertTrue(response.getBody().asString().contains("expectedData"));
    }
}

Run your test case to perform API testing.

This example demonstrates how to perform API testing using RestAssured in Java. Remember to replace the base URL and endpoint with the actual API you want to test. Additionally, you can add more validation steps as needed to ensure the API behaves as expected.
