I have following test class
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest {
@Autowired
MyService service;
...
}
Is it possible to access services-test-config.xml programmatically in one of such methods? Like:
ApplicationContext ctx = somehowGetContext();
This works fine too:
@Autowired
ApplicationContext context;
Since the tests will be instantiated like a Spring bean too, you just need to implement the ApplicationContextAware interface:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest implements ApplicationContextAware
{
@Autowired
MyService service;
...
@Override
public void setApplicationContext(ApplicationContext context)
throws BeansException
{
// Do something with the context here
}
}
For non xml needs, you can also do this:
@RunWith(SpringJUnit4ClassRunner.class)
/* must provide some "root" for the app-context, use unit-test file name to the context is empty */
@ContextConfiguration(classes = MyUnitTestClass.class)
public class MyUnitTestClass implements ApplicationContextAware {
If your test class extends the Spring JUnit classes
(e.g., AbstractTransactionalJUnit4SpringContextTests or any other class that extends AbstractSpringContextTests), you can access the app context by calling the getContext() method.
Check out the javadocs for the package org.springframework.test.
It's possible to inject instance of ApplicationContext class by using SpringClassRule
and SpringMethodRule rules. It might be very handy if you would like to use
another non-Spring runners. Here's an example:
@ContextConfiguration(classes = BeanConfiguration.class)
public static class SpringRuleUsage {
@ClassRule
public static final SpringClassRule springClassRule = new SpringClassRule();
@Rule
public final SpringMethodRule springMethodRule = new SpringMethodRule();
@Autowired
private ApplicationContext context;
@Test
public void shouldInjectContext() {
}
}
Created one post related to this issue, this really helpful to gain confidence
Try this link for more details
@Test
void TestBeanLaunch()
{
context.run(it -> {
/*
* I can use assertThat to assert on the context
* and check if the @Bean configured is present
* (and unique)
*/
assertThat(it).hasSingleBean(PracticeApplication.class);
assertThat(it).hasSingleBean(PracticeApplication.TestBean.class);
assertThat(it.getBean("BeanTest")).isInstanceOf(PracticeApplication.TestBean.class);
});
}
JUnit4.class, which the answers are ignoring. I need to Google around a bit more.
