+# UnitTestShouldUseAfterAnnotation
+
+*Usage:* 
+`pmd check -d <source code folder> -R category/java/bestpractices.xml/UnitTestShouldUseAfterAnnotation -format <output format>`
+
+*Description:*
+
+In JUnit 3, the tearDown method was used to clean up all data entities required in running tests.
+JUnit 4 skips the tearDown method and executes all methods annotated with @After after running each test.
+JUnit 5 introduced @AfterEach and @AfterAll annotations to execute methods after each test or after all tests in the class, respectively.
+        
+
+*Example:*
+```java
+
+
+public class MyTest {
+    public void tearDown() {
+        bad();
+    }
+}
+public class MyTest2 {
+    @After public void tearDown() {
+        good();
+    }
+}
+
+        
+```
