`@TestPropertySource`

@TestPropertySource is a class-level annotation that you can use to configure the locations of properties files and inlined properties to be added to the set of PropertySources in the Environment for an ApplicationContext loaded for an integration test.

The following example demonstrates how to declare a properties file from the classpath:

Java
Kotlin

@ContextConfiguration
@TestPropertySource("/test.properties") (1)
class MyIntegrationTests {
	// class body...
}

1	Get properties from `test.properties` in the root of the classpath.

@ContextConfiguration
@TestPropertySource("/test.properties") (1)
class MyIntegrationTests {
	// class body...
}

1	Get properties from `test.properties` in the root of the classpath.

The following example demonstrates how to declare inlined properties:

Java
Kotlin

@ContextConfiguration
@TestPropertySource(properties = { "timezone = GMT", "port: 4242" }) (1)
class MyIntegrationTests {
	// class body...
}

1	Declare `timezone` and `port` properties.

@ContextConfiguration
@TestPropertySource(properties = ["timezone = GMT", "port: 4242"]) (1)
class MyIntegrationTests {
	// class body...
}

1	Declare `timezone` and `port` properties.
