Run the unit tests

Fix the unit test

We changed the response message to hello beautiful world and the unit test was expecting hello world. This is an easy fix, let’s update the unit test.

Open the file sam-app/HelloWorldFunction/src/test/java/helloworld/ and update the expected value for the response to match the new message. The unit test should look like this after the update:

package helloworld;

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;
import org.junit.Test;

public class AppTest {
  public void successfulResponse() {
    App app = new App();
    APIGatewayProxyResponseEvent result = app.handleRequest(null, null);
    assertEquals(result.getStatusCode().intValue(), 200);
    assertEquals(result.getHeaders().get("Content-Type"), "application/json");
    String content = result.getBody();
    assertTrue(content.contains("\"hello beautiful world\""));

Note: Make sure you save the files after changing them.

Run the tests again

Run the same command again.

sam build

Now the tests should pass: UnitTestsSucceed

Then rerun our local deployment

sam local start-api --port 8080

Now refresh the browser tab or re-trigger the CURL command to see the changes reflected in your endpoint. SamLocalCodeChange
