In the last tutorial, I explained How to test POST Request using Rest Assured. In this tutorial, I will automate a PATCH Request using Rest Assured. I will verify the status code, line of Status, and content of the Response.
To set up a basic Rest Assured Maven Project, click here and Gradle project, click here.
Add the below-mentioned dependencies to the pom.xml.
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<version>5.3.2</version>
<scope>test</scope>
</dependency>
What is the PATCH Method?
The HTTP PATCH request method applies partial modifications to a resource.
Difference between PUT and PATCH Method
PUT is a method of modifying resources where the client sends data that updates the entire resource.
PATCH is a method of modifying resources where the client sends partial data that is to be updated without modifying the entire data.
Below are the steps to test a PATCH Request using Rest Assured:
The steps to test the PATCH request are similar to the PUT request.
Below is the example for the test to PATCH method. (Non BDD)
import io.restassured.RestAssured;
import io.restassured.http.ContentType;
import io.restassured.response.Response;
import io.restassured.response.ValidatableResponse;
import io.restassured.specification.RequestSpecification;
import org.junit.Test;
import static org.hamcrest.CoreMatchers.equalTo;
public class Patch_NonBDDDemo {
RequestSpecification requestSpecification;
Response response;
ValidatableResponse validatableResponse;
@Test
public void updateUser() {
String jsonString = "{\"name\": \"William\"}";
RestAssured.baseURI = "https://reqres.in/api/users/2";
// Create a request specification
requestSpecification = RestAssured.given();
// Setting content type to specify format in which request payload will be sent.
requestSpecification.contentType(ContentType.JSON);
// Adding body as string
requestSpecification.body(jsonString);
// Calling PATCH method
response = requestSpecification.patch();
// Let's print response body.
String responseString = response.prettyPrint();
/*
* To perform validation on response, we need to get ValidatableResponse type of
* response
*/
validatableResponse = response.then();
// Get status code
validatableResponse.statusCode(200);
// It will check if status line is as expected
validatableResponse.statusLine("HTTP/1.1 200 OK");
// Check response - name attribute
validatableResponse.body("name", equalTo("William"));
}
}
The output of the above program is
Test implemented in BDD Format
import io.restassured.http.ContentType;
import io.restassured.response.Response;
import io.restassured.response.ValidatableResponse;
import io.restassured.specification.RequestSpecification;
import org.junit.Test;
import static io.restassured.RestAssured.given;
import static org.hamcrest.CoreMatchers.equalTo;
public class Patch_BDDDemo {
RequestSpecification requestSpecification;
Response response;
ValidatableResponse validatableResponse;
@Test
public void updateUser() {
String jsonString = "{\"name\": \"William\"}";
// Update name
validatableResponse = given()
.baseUri("https://reqres.in/api/users/2")
.contentType(ContentType.JSON)
.body(jsonString)
.when()
.patch()
.then()
.assertThat().statusCode(200)
.body("name", equalTo("William"));
System.out.println("Response :" + validatableResponse.extract().asPrettyString());
}
}
The output of the above program is
