[FIXED] SpringRunner Integration Test Autowired is null

Issue

I am have a normal Spring Application (Not a Spring Boot )

When I am running the Integration Test using Spock , the dependent dataUtils Autowired is null

These are my classes

RunWith(SpringRunner.class)

@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = AppConfig.class)
class DataProcessorTest extends Specification  {

def 'call '() {
    given:
      DataProcesser dataProcessor = new DataProcesser()
    when:
      dataProcessor.importData()
    then:
      assert  2 == 2
  }
}

Can anybody please let me know what could be the issue ??

Solution

You create DataProcessor object as normal object using new, not as bean.

@Autowired is a method of automatically injecting a bin into an object created as bin.

If you use @Autowired and dataUtils in DataProcessor is not null, you must create DataProcessor for bean, like below.

@RunWith(SpringRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = AppConfig.class)
class DataProcessorTest extends Specification  {

@Autowired
DataProcessor dataProcessor;

def 'call '() {
    when:
      dataProcessor.importData()
    then:
      assert  2 == 2
  }
}
