spring - what is the idiomatic way to use ConfigurationProperties and EnableConfigurationProperties in tests? -

i trying setup unit tests elements used within spring(-boot) application, , struggled setup around configurationproperties , enableconfigurationproperties. way got work doesn't seem consistent examples have seen in have witnessed needing both configurationproperties , enableconfigurationproperties on configuration class, doesn't seem right, , hoping might provide guidance.

here simplified example:

javatestconfiguration.java

package com.kerz;  import org.springframework.boot.context.properties.configurationproperties; import org.springframework.boot.context.properties.enableconfigurationproperties; import org.springframework.context.annotation.bean; import org.springframework.context.annotation.configuration;  import javax.validation.constraints.notnull;  @configuration @configurationproperties @enableconfigurationproperties public class javatestconfiguration {    public void setfoo(string foo) {     this.foo = foo;   }    @notnull   string foo;    @bean   string foo() {     return foo;   } } 

javatestconfigurationtest.java

package com.kerz;  import org.junit.test; import org.junit.runner.runwith; import org.springframework.beans.factory.annotation.autowired; import org.springframework.test.context.contextconfiguration; import org.springframework.test.context.testpropertysource; import org.springframework.test.context.junit4.springjunit4classrunner;  import static org.junit.assert.assertequals;  @runwith(springjunit4classrunner.class) @contextconfiguration(classes = {javatestconfiguration.class}) @testpropertysource("classpath:test.properties") public class javatestconfigurationtest {    @autowired   string foo;    @test   public void shouldwork() throws exception {     assertequals("foo", "bar", foo);   } } 

test.properties

foo=bar 

your test more integration test if starting spring context. therefore should test production spring configuration.

i advise not create testing configuration. use 1 production configuration testing.

you using @testpropertysource annotation, used when need define test specific properties. if can test prod configuration not use it.
