Question: How do you handle scenarios where the API returns unexpected content types?

Answer: RestAssured allows you to validate unexpected content types using the contentType() method.

import static io.restassured.RestAssured.*;

public class UnexpectedContentTypeHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        given()

            .get("/resource")

        .then()

            .contentType("text/plain"); // Validates if the response content type is "text/plain"

    }

}

Question: How do you handle scenarios where the API returns unexpected HTTP status codes?

Answer: RestAssured allows you to validate unexpected HTTP status codes using the not() method. 

import static io.restassured.RestAssured.*;

public class UnexpectedStatusCodeHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        given()

            .get("/resource")

        .then()

            .statusCode(not(404)); // Validates if the response status code is not 404

    }

}

Question: How do you handle exceptions such as connection timeouts in RestAssured tests?

Answer: You can handle connection timeouts by setting a timeout duration using the timeout() method. Additionally, you can catch the java.net.SocketTimeoutException exception.

import static io.restassured.RestAssured.*;

public class ConnectionTimeoutHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        try {

            given()

                .get("/resource")

                .timeout(5000) // Set a timeout of 5 seconds

            .then()

                .statusCode(200);

        } catch (java.net.SocketTimeoutException e) {

            // Handle timeout exception

            System.out.println("Connection timed out.");

        }

    }

}

Question: How do you handle exceptions such as invalid SSL certificates in RestAssured tests?

Answer: You can handle invalid SSL certificates by disabling SSL certificate validation using the relaxedHTTPSValidation() method.

 

import static io.restassured.RestAssured.*;

public class InvalidSSLCertificateHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        given()

            .relaxedHTTPSValidation()

            .get("/resource")

        .then()

            .statusCode(200);

    }

}

Question: How do you handle exceptions such as resource not found errors in RestAssured tests?

Answer: You can handle resource not found errors by expecting specific error responses using the expect() method.

import static io.restassured.RestAssured.*;

public class ResourceNotFoundErrorHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        given()

            .get("/nonexistent-resource")

        .then()

            .statusCode(404)

            .statusLine("HTTP/1.1 404 Not Found");

    }

}

Question: How do you handle exceptions such as JSON parsing errors in RestAssured tests?

Answer: You can handle JSON parsing errors by expecting specific error responses or by catching the io.restassured.path.json.exception.JsonPathException exception.

import static io.restassured.RestAssured.*;

public class JsonParsingErrorHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        try {

            given()

                .get("/malformed-json-resource")

            .then()

                .statusCode(200)

                .extract().jsonPath();

        } catch (io.restassured.path.json.exception.JsonPathException e) {

            // Handle JSON parsing error

            System.out.println("JSON parsing error occurred.");

        }

    }

}

Question: How do you handle exceptions such as server errors (5xx) in RestAssured tests?

Answer: You can handle server errors by expecting specific error responses using the expect() method. 

import static io.restassured.RestAssured.*;

public class ServerErrorHandlingExample {

    public static void main(String[] args) {

        baseURI = "https://api.example.com";

        given()

            .get("/error-endpoint")

        .then()

            .statusCode(500)

            .statusLine("HTTP/1.1 500 Internal Server Error");

    }

}
