Springboot and maven: how to launch unit tests automatically with two profiles

问题

This question is the continuation of question "SpringBoot: how to run tests twice, with two different config files".

I use to compile my project using mvn clean install. Doing that, maven also launches my unit tests and I immediately knows whether my development is correct.

I am actually working on a module that embeds a JMS connection. my module supports two JMS buses: EMS and AMQ. The bus to be used is specified in the configuration of my module

As a consequence, I need to create two profiles, one for EMS and one for AMQ.

However, when I launch my mvn clean install I want that maven launches automatically the tests using the two profiles, not only one; I don't want to have to launch it twice: mvn clean test -Dspring.profiles.active=ems ; mvn clean test -Dspring.profiles.active=amq

Thank you for help

回答1:

You can pass the two profiles separated by a comma:

mvn clean install -Dspring.profiles.active=ems,amq

And then you'll have two active profiles:

The following profiles are active: ems,amq

回答2:

You can also specify in the src/test/resources/application.properties specific properties that apply every time Spring tests are run. Seems cleaner to me than specifying them on Maven command line. For your case :

spring.profiles.active=ems,amq

回答3:

I think that there is a miss-understanding; It seems that when I run my tests with spring.profiles.active=ems,amq:

• all tests are launched one time
• both profiles are enabled

What I want is different:

• launch all tests TWO TIMES
• first time with ems (and only ems) profile enabled
• second time with amq (and only amq) profile enabled

For the moment, I do not succeed to find a solution; evey clue is welcome

I found a solution for my issue; a kind of trick based on:

• overloading the SpringJUnit4ClassRunner

• redefining the run() method in order to:

  1. call force the use of the first profile
  2. call the origial run() method
  3. do the same with the other profile

---

public class MultiProfileTestRunner extends SpringJUnit4ClassRunner {
...


public void run(RunNotifier notifier) {
    System.setProperty("spring.profiles.active", "ems");
    super.run(notifier);

    System.setProperty("spring.profiles.active", "amq");
    super.run(notifier);
}

Between both calls to super.run() we have to 'force' Spring to reload its context, otherwize the profile change is not taken into account

I did it by using the annotation @DirtiesContext(classMode = AFTER_CLASS) on my tests
