When I run my selenium test below from within Eclipse, I get a series of Could not instantiate TestExecutionListener
messages in my log.
This is the actual test.
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
public final class TestWebpage {
private static final Logger LOG = Logger.getLogger(TestWebpage.class);
@Autowired
private WebDriver driver;
@Test
public void testLoadingPage() {
LOG.debug("Hello World!");
}
}
And this is the log
0 [main] INFO org.springframework.test.context.support.DefaultTestContextBootstrapper - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener, org.springframework.test.context.support.DependencyInjectionTestExecutionListener, org.springframework.test.context.support.DirtiesContextTestExecutionListener, org.springframework.test.context.transaction.TransactionalTestExecutionListener, org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener]

Note that I am using Spring 4.1.0.RELEASE
.
I noticed in the answer to a previous question the suggestion to add @WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
@WebAppConfiguration
public final class TestWebpage {
Which I then needed three extra dependencies in my pom.xml to support:
javax.servlet-api
spring-jdbc
spring-web
Why do I need all this extra when I am not actually using JDBC at all, or anything using spring-web/servlet - this is just a selenium test with some of my own configuration.
Is there an easier way? Am I missing something bigger?
This is the class I configure my tests with.
public final class SeleniumConfig {
@Bean
public String baseUrl() {
return "http://localhost:8888/";
}
@Bean
public WebDriver driver() {
return new CloseableFirefoxDriver();
}
class CloseableFirefoxDriver extends FirefoxDriver implements DisposableBean {
public void destroy() throws Exception {
quit();
}
}
}
My pom.xml (before I added the extra dependencies).

If I leave in the three extra dependencies
javax.servlet-api
spring-jdbc
spring-web
I can leave my test class defined as this:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
public final class TestWebpage {
and I will get this logging:
0 [main] INFO org.springframework.test.context.support.DefaultTestContextBootstrapper - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener, org.springframework.test.context.support.DependencyInjectionTestExecutionListener, org.springframework.test.context.support.DirtiesContextTestExecutionListener, org.springframework.test.context.transaction.TransactionalTestExecutionListener, org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener]

No errors, but obviously Spring is doing a fair bit of work in the background.
Alternatively, I can remove the three extra dependencies and add this minimal @TestExecutionListeners
annotation.
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
@TestExecutionListeners(listeners = {DependencyInjectionTestExecutionListener.class})
public final class TestWebpage {
I get logging as below:
0 [main] INFO org.springframework.test.context.support.DefaultTestContextBootstrapper - Using TestExecutionListeners: [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@4fce6eaf]
117 [main] INFO org.springframework.context.support.GenericApplicationContext - Refreshing org.springframework.context.support.GenericApplicationContext@42695958: startup date [Wed Oct 01 21:59:05 EST 2014]; root of context hierarchy

4190 [Thread-8] INFO org.springframework.context.support.GenericApplicationContext - Closing org.springframework.context.support.GenericApplicationContext@42695958: startup date [Wed Oct 01 21:59:05 EST 2014]; root of context hierarchy
At least no errors.
As to why I need any of this, I don't understand yet. I am leaving this here as a reference, at the very least to show the minimal changes required to get rid of the Could not instantiate TestExecutionListener
messages.
To stay close to the original Spring implementation, use this instead:
@TestExecutionListeners(listeners = { DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class, TransactionalTestExecutionListener.class })
as defined in org.springframework.test.context.TestContextManager:
private static final String[] DEFAULT_TEST_EXECUTION_LISTENER_CLASS_NAMES = new String[] {
"org.springframework.test.context.web.ServletTestExecutionListener",
"org.springframework.test.context.support.DependencyInjectionTestExecutionListener",
"org.springframework.test.context.support.DirtiesContextTestExecutionListener",
"org.springframework.test.context.transaction.TransactionalTestExecutionListener" };
Only ServletTestExecutionListener should be evicted.
