在集成测试之前运行主 springboot 应用程序

Question

How can i run main application before integration tests by maven? Now i have a really bad solution. Tests with commented code work properly but i need good practices way.

@Slf4j
@SpringBootTest
@RunWith(SpringRunner.class)
@Category(Integration.class)
@ActiveProfiles("test")
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public class MyTestClass {

@BeforeClass
public static void setUp(){

    /*SpringApplication.run(MyApplication.class).close();

    System.setProperty("spring.profiles.active", "test");
    MyApplication.main(new String[0]);*/
}

I want run tests by maven with arguments:

clean integration-test -Dgroups=xxx.annotation.type.Integration -Drun.jvmArguments=-Dspring.profiles.active=test

but it doesn't work. How can i correct this maven command line?

Answer 1

To run your application on a specific profile for your integration test, you need to annotate the test class with @SpringBootTest and @ActiveProfiles with parameters as below:

@SpringBootTest(classes = {MyApplication.class},  webEnvironment = WebEnvironment.RANDOM_PORT)
@ActiveProfiles("test")

The application you define in classes = {MyApplication.class} would be started on a random port when you provide webEnvironment = WebEnvironment.RANDOM_PORT using the profile specified on @ActiveProfiles . In case you want it to be run on the defined port, then use WebEnvironment.DEFINED_PORT . In case you need to get port (random port), you can autowire its value to local field to test like this:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class TestClass {
    @LocalServerPort
    private int port;
    @Test public void someTest() {}
}

You can use the spring-boot-maven-plugin and bind it to the pre-integration-test phase in maven like this:

 <project> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.0.4.RELEASE</version> <executions> <execution> <id>pre-integration-test</id> <goals> <goal>start</goal> </goals> </execution> <execution> <id>post-integration-test</id> <goals> <goal>stop</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
