# UnitTestShouldIncludeAssert

*Usage:* 
`pmd check -d <source code folder> -R category/java/bestpractices.xml/UnitTestShouldIncludeAssert -format <output format>`

*Description:*

JUnit tests should include at least one assertion.  This makes the tests more robust, and using assert
with messages provide the developer a clearer idea of what the test does.
        

*Example:*
```java


public class Foo extends TestCase {
   public void testSomething() {
      Bar b = findBar();
   // This is better than having a NullPointerException
   // assertNotNull("bar not found", b);
   b.work();
   }
}

        
```
