Usage with Maven

Add the following dependency to your pom.xml

<dependency>
	<groupId>de.jakop.validation</groupId>
	<artifactId>annotation-validator</artifactId>
	<version>2.0.2</version>
	<scope>test</scope>
</dependency>

Examples

Consider the following class

@MyAnnotation
class AnnotatedTestClass {

	@MyAnnotation(foo = "bar")
	private String fieldWithAnnotations;

	@AnotherAnnotation(TEST)
	public void methodWithAnnotations() {
		// noop
	}
}

If you would like to check the class to be annotated only with @MyAnnotation and only have the configured params use the following

import static AnnotationDefinition.*;

...

validate().exactly() //
	.annotation(type(MyAnnotation.class) //
		.param("foo", "default")) //
	.forClass(AnnotatedTestClass.class);

If you would like to check the class to be annotated only with @MyAnnotation but also want to consider default values for not configured params use the following

import static AnnotationDefinition.*;

...

validate().only() //
	.annotation(type(MyAnnotation.class)) //
	.forClass(AnnotatedTestClass.class);

If you would like to check the field to be annotated with @MyAnnotation, whereas foo has value bar, use the following

validate() //
	.annotation(type(MyAnnotation.class) //
		.param("foo", "bar")) //
	.forField(AnnotatedTestClass.class.getDeclaredField("fieldWithAnnotations"));

If you would like to check the method to be annotated with @AnotherAnnotation, whereas value has value TEST, use the following

validate() //
	.annotation(type(AnotherAnnotation.class) //
		.param("value", TEST)) //
	.forMethod(AnnotatedTestClass.class.getMethod("methodWithAnnotations"));
