Spring-boot application - Integration-testing

This demo project exaplins how JUnit and Zerocode test framework based integration-tests for a spring-boot application can make your life easy everyday.

Keep it simple and easy while doing the integration tests

Where are the integration tests?

• The JUnit integration tests are located under-
  • test/java/integrationtests/get
  • test/java/integrationtests/put

You can run and debug them individually.

Where is the Suite to run all the tests?

The suite JUnit suite test located-

• src/test/java/integrationtests/IntegrationTestSuite.java

Where are the unit tests cases?

The JUnit unit tests are located as usual in their respective package, under root of-

• src/test/java/com/springboot i.e. under package com.springboot

How do they both run in the maven life cycle?

e.g.

mvn clean install

• The unit tests run as usual in the test phase
• Then the integration-tests are fired in the <goal>integration-test</goal> as configured in the pom.xml

  <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-failsafe-plugin</artifactId>
      <executions>
          <execution>
              <goals>
                  <goal>integration-test</goal>
                  <goal>verify</goal>
              </goals>
              <configuration>
                  <includes>
                      <include>integrationtests.IntegrationTestSuite.java</include>
                  </includes>
              </configuration>
          </execution>
      </executions>
  </plugin>

• Please look at the the Suite-Test class <include>integrationtests.IntegrationTestSuite.java</include> which is pointing to the root of the tests in the test-resources folder resource/integration_tests

i.e. as below-

@TargetEnv("abc_bankapp_host.properties")
@TestPackageRoot("integration_tests")  //You can point this to any package you need -or- use Junit Suite runner to point to individual test classes
@RunWith(E2eJunitSuiteRunner.class)
public class IntegrationTestSuite {

}

What does the above @RunWith do?

@RunWith(E2eJunitSuiteRunner.class)

Ans: It starts the spring applications and then fires the tests once by one. See below how it brings up the application.

public class E2eJunitSuiteRunner extends ZeroCodePackageRunner {

    static{
        Application.start();
    }

    public E2eJunitSuiteRunner(Class<?> klass) throws InitializationError {
        super(klass);
    }
}
