public @interface IfProfileValue

Test annotation to indicate whether a test is enabled or disabled for a specific testing profile.

In the context of this annotation, the term profile refers to a Java system property by default; however, the semantics can be changed by implementing a custom ProfileValueSource. If the configured ProfileValueSource returns a matching value() for the declared name(), the test will be enabled. Otherwise, the test will be disabled and effectively ignored.

@IfProfileValue can be applied at the class level, the method level, or both. Class-level usage of @IfProfileValue takes precedence over method-level usage for any methods within that class or its subclasses. Specifically, a test is enabled if it is enabled both at the class level and at the method level; the absence of @IfProfileValue means the test is implicitly enabled. This is analogous to the semantics of JUnit's @Ignore annotation, except that the presence of @Ignore always disables a test.

Example

When using SystemProfileValueSource as the ProfileValueSource implementation (which is configured by default), you can configure a test method to run only on Java VMs from Oracle as follows:

 @IfProfileValue(name = "java.vendor", value = "Oracle Corporation")
 public void testSomething() {
     // ...
 }

'OR' Semantics

You can alternatively configure @IfProfileValue with OR semantics for multiple values(). The following test will be enabled if a ProfileValueSource has been appropriately configured for the "test-groups" profile with a value of either unit-testsorintegration-tests. This functionality is similar to TestNG's support for test groups and JUnit's experimental support for test categories.

 @IfProfileValue(name = "test-groups", values = { "unit-tests", "integration-tests" })
 public void testWhichRunsForUnitOrIntegrationTestGroups() {
     // ...
 }

@IfProfileValue vs. @Profile

Although the @IfProfileValue and @Profile annotations both involve profiles, they are not directly related. @Profile involves bean definition profiles configured in the Environment; whereas, @IfProfileValue is used to enable or disable tests.

Meta-annotation Support

As of Spring Framework 4.0, this annotation may be used as a meta-annotation to create custom composed annotations.
