I have a JUnit test that starts an spring-boot application (in my case, the main class is SpringTestDemoApp) after the test:
@WebIntegrationTest
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = SpringTestDemoApp.class)
public class SpringTest {
@Test
public void test() {
// Test http://localhost:8080/ (with Selenium)
}
}
Everything works fine using spring-boot 1.3.3.RELEASE. Nevertheless, the annotation @WebIntegrationTest and @SpringApplicationConfiguration have been removed in spring-boot 1.5.2.RELEASE. I tried to refactor the code to the new version, but I am not able to do it. With the following test, my app is not started before the test and http://localhost:8080 returns 404:
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringTestDemoApp.class)
@WebAppConfiguration
public class SpringTest {
@Test
public void test() {
// The same test than before
}
}
How can I refactor my test to make it works in spring-boot 1.5?
The webEnvironment option inside @SpringBootTest is very important. It can take values like NONE, MOCK, RANDOM_PORT, DEFINED_PORT.
NONE will only create spring beans and not any mock the servlet environment.
MOCK will create spring beans and a mock servlet environment.
RANDOM_PORT will start the actual servlet container on a random port; this can be autowired using the @LocalServerPort.
DEFINED_PORT will take the defined port in the properties and start the server with it.
The default is RANDOM_PORT when you don’t define any webEnvironment. So the app may be starting at a different port for you.
Try to override it to DEFINED_PORT, or try to autowire the port number and try to run test on that port.
It does not work because SpringBootTest uses random port by default, please use:
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
This is a snippet of what I'm currently using, of course depending on the web-driver you want to use you can create different beans for it.
Make sure you have spring boot test and selenium on your pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>${selenium.version}</version>
<scope>test</scope>
</dependency>
in my case ${selenium.version} is:
<properties>
<selenium.version>2.53.1</selenium.version>
</properties>
and those are the classes:
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Import(IntegrationConfiguration.class)
public abstract class AbstractSystemIntegrationTest {
@LocalServerPort
protected int serverPort;
@Autowired
protected WebDriver driver;
public String getCompleteLocalUrl(String path) {
return "http://localhost:" + serverPort + path;
}
}
public class IntegrationConfiguration {
@Bean
private WebDriver htmlUnitWebDriver(Environment env) {
return new HtmlUnitDriver(true);
}
}
public class MyWhateverIT extends AbstractSystemIntegrationTest {
@Test
public void myTest() {
driver.get(getCompleteLocalUrl("/whatever-path/you/can/have"));
WebElement title = driver.findElement(By.id("title-id"));
Assert.assertThat(title, is(notNullValue()));
}
}
hope it helps!
