My Junit is not picking up properties set in test properties file. I get no error, but value returned from properties file is null
CLASS TO BE TESTED:
package com.abc.mysource.mypackage;
@Component
@ComponentScan
public class MyHelper {
@Autowired
@Qualifier("commonProperties")
private CommonProperties commonProperties;
public LocalDateTime method1ThatUsesCommonProperties(LocalDateTime startDateTime) throws Exception {
String customUserType = commonProperties.getUserType(); // Returns null if run as JUnit test
//Further processing
}
}
SUPPORTING COMPONENTS - BEANS & CONFIG CLASSES:
package com.abc.mysource.mypackage;
@Component
public class CommonProperties {
@Value("${myhelper.userType}")
private String userType;
public String getUserType() {
return userType;
}
public void setCalendarType(String userType) {
this.userType = userType;
}
}
CONFIG CLASS:
package com.abc.mysource.mypackage;
@Configuration
@ComponentScan(basePackages ="com.abc.mysource.mypackage.*")
@PropertySource("classpath:default.properties")
public class CommonConfig {}
default.properties under src/main/resources
myhelper.userType=PRIORITY
MY TEST CLASS:
package com.abc.mysource.mypackage.test;
@RunWith(SpringRunner.class)
@ContextConfiguration(classes=MyHelper.class)
@TestPropertySource("classpath:default-test.properties")
@EnableConfigurationProperties
public class MyHelperTest {
@MockBean(name="commonProperties")
private CommonProperties commonProperties;
@Autowired
private MyHelper myHelper;
@Test
public void testMethod1ThatUsesCommonProperties() {
myHelper.method1ThatUsesCommonProperties();
}
}
default-test.properties defined under /src/test/resources:
myhelper.userType=COMMON
NOTE:
I moved default-test.properties to /src/main/resources - commonProperties.getUserType() is null
I even used @TestPropertySource(properties = {"myhelper.userType=COMMON"}). Same result
NOTE 2:
I tried the solution on @TestPropertySource is not loading properties.
This solution requires me to create a duplicate bean called CommonProperties under src/test/java. But @MockBean fails when I do
@MockBean(name="commonProperties")
private CommonProperties commonProperties;
Please do not mark a duplicate.
NOTE 3: Mine is a spring, not a spring boot application.
