There is no way avoiding new annotation processing:
### Let's create Annotation Descriptor as follows
```java
public class TestEnabledCondition implements ExecutionCondition {
static class AnnotationDescription {
String prefix;
String property;
Boolean value;
AnnotationDescription(String prefix, String property) {
this.prefix = prefix;
this.property = property;
}
String getName() {
return prefix + property;
}
AnnotationDescription setValue(Boolean value) {
this.value = value;
return this;
}
Boolean getValue() {
return value;
}
}
/* ... */
}
```
It helps us to process annotations using lamdas.
### Then create a method to extract prefix from context
```java
public class TestEnabledCondition implements ExecutionCondition {
/* ... */
private AnnotationDescription makeDescription(ExtensionContext context, String property) {
String prefix = context.getTestClass()
.map(cl -> cl.getAnnotation(TestEnabledPrefix.class))
.map(TestEnabledPrefix::prefix)
.map(pref -> !pref.isEmpty() && !pref.endsWith(".") ? pref + "." : "")
.orElse("");
return new AnnotationDescription(prefix, property);
}
/* ... */
}
```
### And now process the annotation value
``` java
public class TestEnabledCondition implements ExecutionCondition {
