Spring Boot Integration Testing

Question

I have been trying to write a integration test for a small Spring boot Project that I have written but for some reason seem unable to get integration tests to work. Here is what I am trying to do:

package au.azzmosphere.integration;


import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = {IntegrationTestConfiguration.class})
public class TestIntegration1 {
    @Test
    public void testDummy() {

    }
}

the configuration class has the following:

package au.azzmosphere.integration;

import au.azzmosphere.configuration.RobotAppConfig;
import org.springframework.context.annotation.Configuration;

@Configuration
public class IntegrationTestConfiguration extends RobotAppConfig {
}

The code is consistently getting the following errors when I try to run the Integration Test from IntelliJ

14:54:01.537 [main] DEBUG org.springframework.test.context.junit4.SpringJUnit4ClassRunner - SpringJUnit4ClassRunner constructor called with [class au.azzmosphere.integration.TestIntegration1].
14:54:01.542 [main] INFO org.springframework.test.context.TestContext - @ContextConfiguration not found for class [class au.azzmosphere.integration.TestIntegration1].
14:54:01.549 [main] INFO org.springframework.test.context.TestContextManager - @TestExecutionListeners is not present for class [class au.azzmosphere.integration.TestIntegration1]: using defaults.

From gradle the following is returned

au.azzmosphere.integration.TestIntegration1 > initializationError FAILED
    java.lang.NoClassDefFoundError
        Caused by: java.lang.ClassNotFoundException

The full stack trace is

java.lang.NoClassDefFoundError: org/springframework/transaction/TransactionDefinition

I have added the full stack trace to the answer hope it helps. — Aaron Spiteri, Sep 04 '17 at 05:16

Looks like the TestExecutionListeners automatically puts the TransactionalTestExecutionListener into the application if you the 'TestExecutionListeners' annotation is not used. I have now added the following — Aaron Spiteri, Sep 04 '17 at 05:31
`@TestExecutionListeners({DependencyInjectionTestExecutionListener.class})` and it has gotten rid of the original exception but has introduced a new one — Aaron Spiteri, Sep 04 '17 at 05:32
ERROR org.springframework.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@68837a77] to prepare test instance [au.azzmosphere.integration.TestIntegration1@2d554825] java.lang.IllegalArgumentException: Can not build an ApplicationContext with a NULL 'contextLoader'. Consider annotating your test class with @ContextConfiguration. — Aaron Spiteri, Sep 04 '17 at 05:32
I thought that this was taken care of by the SpringBoot annotation but may be wrong. — Aaron Spiteri, Sep 04 '17 at 05:32
@gladiator I checked out that MyKong page, attempted to apply the suggestion and it worked some what, but still just progresses to the next exception that I am getting :( which is `16:03:56.893 [main] DEBUG org.springframework.test.context.support.DependencyInjectionTestExecutionListener - Performing dependency injection for test context [[TestContext@3dd3bcd testClass = TestIntegration1, locations = array['classpath:/au/azzmosphere/integration/TestIntegration1-context.xml'], testInstance =` — Aaron Spiteri, Sep 04 '17 at 06:05
Ok finally got somewhere, I removed the dependency injections all together. — Aaron Spiteri, Sep 04 '17 at 06:18
`@TestExecutionListeners({})` and it now executes the dummy test, — Aaron Spiteri, Sep 04 '17 at 06:20

Worked it out, :) The problem was that I did not have any TransactionDefinition defined because I didn't use it. The default SpringBoot annotation attempts to inject it. The answer was to use @TestExecutionListeners({DependencyInjectionTestExecutionListener.class}) which overrides the defaults and gets things going.
