Run a testsuite in multiple environment - spring

Question

I want to run my test suite in multiple environment like below:
ApplicationContextTest.class
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("/application-context.xml")
public class MyTest{
#Autowired
private ApplicationContext applicationContext;
#Test
public void test1() {
((ConfigurableEnvironment)applicationContext.getEnvironment()).setActiveProfiles("env1");
((GenericXmlApplicationContext)applicationContext).refresh();
}
#Test
public void test2() {
((ConfigurableEnvironment)applicationContext.getEnvironment()).setActiveProfiles("env2");
((GenericXmlApplicationContext)applicationContext).refresh();
}
}
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<beans profile="env1">
</beans>
<beans profile="env2">
</beans>
When I run test, I got an exception
Caused by: java.lang.IllegalStateException: GenericApplicationContext does not support multiple refresh attempts: just call 'refresh' once
Are there any ways to set Active Profile after ApplicationContext started up?
Or Any solution to solve above exception?
Thanks.

Answer 1

The normal way to choose one or more specific profile(s) is to set a system property when running the tests
-Dspring.profiles.active=env1
You can also set one or more profile(s) as default with the system property
-Dspring.profiles.default=env1
I normally do this in a static init method of my test
#BeforeClass
public static void init() {
// set default spring test profile
System.setProperty("spring.profiles.default", "default");
}
You will find some information if you search for these properties (If you need a Spring code reference you have to look at the AbstractEnvironment class).
I do not know of any way how to change the profile after startup. In this case you may have to use a new JVM on each test (can e.g. be done by the maven surefire plugin using the reuseForks setting). Or even better place the tests that use the same profile in the same test class and set the profile as needed.
IMHO a test should not depend on a specific profile. A test should pass - whatever profile is used. Than you can easily change e.g. between test (mock) or 'real' environments.
