Load different application.yml in SpringBoot Test

Question

I'm using a spring boot app which runs my src/main/resources/config/application.yml.

When I run my test case by :

@RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = Application.class) @WebAppConfiguration @IntegrationTest public class MyIntTest{ } 

The test codes still run my application.yml file to load properties. I wonder if it is possible to run another *.yml file when running the test case.

Answer 1

One option is to work with profiles. Create a file called application-test.yml, move all properties you need for those tests to that file and then add the @ActiveProfiles annotation to your test class:

@RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = Application.class) @WebAppConfiguration @IntegrationTest @ActiveProfiles("test") // Like this public class MyIntTest{ } 

Be aware, it will additionally load the application-test.yml, so all properties that are in application.yml are still going to be applied as well. If you don't want that, either use a profile for those as well, or override them in your application-test.yml.

You can set your test properties in src/test/resources/config/application.yml file. Spring Boot test cases will take properties from application.yml file in test directory.

The config folder is predefined in Spring Boot.

As per documentation:

If you do not like application.properties as the configuration file name, you can switch to another file name by specifying a spring.config.name environment property. You can also refer to an explicit location by using the spring.config.location environment property (which is a comma-separated list of directory locations or file paths). The following example shows how to specify a different file name:

java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties 

The same works for application.yml
