Finally — using REST-Assured in your IDE

If you’ve made the proper pom.xml entries we went over at the top of this post, you should be able to begin using REST-Assured.

• In your IDE, create a new java class named WordPress_API
• Import the following:

import org.junit.Test;
import org.junit.Before;
import static com.jayway.restassured.RestAssured.expect;
import static org.hamcrest.Matchers.equalTo;

• Create a public method named simpleExample
• Add the junit @Test annotation above it.
• Inside simpleExample, add the following code:

expect().body(“title”, equalTo(“Hello world!”)).when().get(“http://localhost:64217/wp-json.php/posts/1”);

• Your code should look like the following:

• Run the jUnit test.
• The test should pass.

Now — just to prove that this is really working, let’s force it to fail so that we can be confident that everything’s kosher.

• Change the Hello world! To Hello JOE!
• Rerun the test.
• The test should now fail.

The REST-assured syntax is pretty flexible. For example, we could have also written our test this way:

RestAssured.baseURI = “http://localhost:64217/”;

RestAssured.get(“wp-json.php/posts/1”).then().assertThat().body(“title”, equalTo(“Hello world!”));

Also, if you’re familiar with Selenium, REST-Assured can also use hamcrest for testing using hamcrest’s library of matchers for building test expressions.
