SpringBoot Property Override not Working For YML Files.

Spring Boot Version:1.5.10

When I try to override a property in application.yml file while executing some tests, application still uses the main property instead of the one in application-test.yml.

I created a simple project to reproduce the issue: https://github.com/selmantayyar/SpringBootPropertyOverrideIssue

Please be aware that with *.properties file,issue does not exist.

Thanks for the sample. @PropertySource and @TestPropertySource do not support yaml files. I've raised SPR-16563 to remind me to document that

Thanks for the prompt reply! So can I assume that only way to override YAML is place application.yml under test/resources/config directory?

No, @SpringBootTest has a properties attribute you can use to override individual properties. If you have more questions, please ask on StackOverflow or join us on Gitter.

I don't understand why Spring offers .yaml as an alternative to .properties files but at the same time does not support overriding properties with @TestPropertySource(properties = ...) Why should i have to use a Spring Boot Dependency (spring-boot-test) if I'm working on a Spring BATCH application?? Doesnt make sense to me. Using @SpringBootTest didn't even work for me, it just ignored the property..
