Spring profiles and testing

Question

I ve got a web application where I have the typical problem that it requires different configuration files for different environments  Some configuration is placed in the application server as JNDI datasources  however some configuration stays in property files   Therefore I want to use the Spring profiles feature   My problem is that I don t get the test case running   context xml    lt context property-placeholder    location  classpath META-INF spring config   spring profiles active  properties   gt    Test    RunWith SpringJUnit4ClassRunner class   TestExecutionListeners       TestPreperationExecutionListener class         Transactional  ActiveProfiles profiles    localtest    ContextConfiguration locations          classpath context xml     public class TestContext       Test   public void testContext             The problem seems to be that the variable for loading the profile isn t resolved   Caused by  java io FileNotFoundException  class path resource  META-INF spring config   spring profiles active  properties  cannot be opened because it does not exist at org springframework core io ClassPathResource getInputStream ClassPathResource java 157  at org springframework core io support PropertiesLoaderSupport loadProperties PropertiesLoaderSupport java 181  at org springframework core io support PropertiesLoaderSupport mergeProperties PropertiesLoaderSupport java 161  at org springframework context support PropertySourcesPlaceholderConfigurer postProcessBeanFactory PropertySourcesPlaceholderConfigurer java 138      31 more   The current profile should be set with the  ActiveProfile annotation  As it s a test case I won t be able to use the web xml  If possible I d like to avoid runtime options as well  The test should run as is  if possible    How can I properly activate the profile  Is it possible to set the profile with a context xml  Could I declare the variable in a test-context xml that is actually calling the normal context

EnableConfigurationProperties needs to be there  you also can annotate your test class   the application-localtest yml from test resources will be loaded  A sample with jUnit5  ExtendWith SpringExtension class   EnableConfigurationProperties  ContextConfiguration classes    YourClasses   initializers   ConfigFileApplicationContextInitializer class   ActiveProfiles profiles    quot localtest quot   class TestActiveProfile         Test     void testActiveProfile

Can I recommend doing it this way  define your test like this    RunWith SpringJUnit4ClassRunner class   TestExecutionListeners       TestPreperationExecutionListener class         Transactional  ActiveProfiles profiles    localtest    ContextConfiguration public class TestContext       Test   public void testContext             Configuration    PropertySource  classpath  myprops properties      ImportResource   classpath context xml       public static class MyContextConfiguration           with the following content in myprops properties file   spring profiles active localtest   With this your second properties file should get resolved   META-INF spring config   spring profiles active  properties

Looking at Biju s answer I found a working solution   I created an extra context-file test-context xml    lt context property-placeholder location  classpath config spring-test properties   gt    Containing the profile   spring profiles active localtest   And loading the test with    RunWith SpringJUnit4ClassRunner class   TestExecutionListeners       TestPreperationExecutionListener class         Transactional  ActiveProfiles profiles    localtest    ContextConfiguration locations          classpath config test-context xml     public class TestContext       Test   public void testContext             This saves some work when creating multiple test-cases

public class LoginTest extends BaseTest        Test     public void exampleTest                 Test           Inherits from a base test class  this example is testng rather than jUnit  but the ActiveProfiles is the same     ContextConfiguration locations      classpath spring-test-config xml      ActiveProfiles resolver   MyActiveProfileResolver class  public class BaseTest extends AbstractTestNGSpringContextTests       MyActiveProfileResolver can contain any logic required to determine which profile to use    public class MyActiveProfileResolver implements ActiveProfilesResolver        Override     public String   resolve Class lt   gt  aClass               This can contain any custom logic to determine which profiles to use         return new String      exampleProfile               This sets the profile which is then used to resolve dependencies required by the test

The best approach here is to remove  ActiveProfiles annotation and do the following    RunWith SpringJUnit4ClassRunner class   TestExecutionListeners       TestPreperationExecutionListener class         Transactional  ContextConfiguration locations          classpath config test-context xml     public class TestContext       BeforeClass   public static void setSystemProperty             Properties properties   System getProperties            properties setProperty  spring profiles active    localtest            AfterClass   public static void unsetSystemProperty             System clearProperty  spring profiles active            Test   public void testContext             And your test-context xml should have the following    lt context property-placeholder    location  classpath META-INF spring config   spring profiles active  properties   gt
