Using Rest Assured with Basic Authentication

Here's an example Java program that demonstrates how to use Rest Assured to test a GET request to a REST API endpoint with Basic Authentication:

import io.restassured.RestAssured;
import io.restassured.response.Response;

public class ApiGetWithBasicAuthTest {

    public static void main(String[] args) {
        // Set base URI of the REST API
        RestAssured.baseURI = "https://api.example.com";

        // Set basic authentication credentials
        String username = "your_username";
        String password = "your_password";

        // Send GET request to /endpoint with basic authentication
        Response response = RestAssured.given()
                .auth()
                .preemptive()
                .basic(username, password)
                .get("/endpoint");

        // Get and print the response body
        String responseBody = response.getBody().asString();
        System.out.println("Response Body:");
        System.out.println(responseBody);

        // Get and print the status code
        int statusCode = response.getStatusCode();
        System.out.println("\nStatus Code: " + statusCode);
    }
}

In this example:

• We set the base URI of the REST API using RestAssured.baseURI.
• We set the basic authentication credentials using .auth().preemptive().basic(username, password).
• We send a GET request to the specified endpoint with basic authentication using RestAssured.given().auth().preemptive().basic(username, password).get("/endpoint").
• We retrieve the response body and status code from the response object and print them out.

Replace "https://api.example.com" with the base URI of your REST API, and "your_username" and "your_password" with your actual username and password for basic authentication. Additionally, replace "/endpoint" with the specific endpoint you want to test. Make sure you have Rest Assured and its dependencies added to your project's classpath.
