body: <p>Is there a less bloated way to test constraints? It seems to me that this is too much code to test constraints.</p>
  
  <pre><code>class BlogPostTests extends GrailsUnitTestCase {
  
      protected void setUp() {
          super.setUp()
          mockDomain BlogPost
      }
  
      void testConstraints() {
          BlogPost blogPost = new BlogPost(title: "", text: "")
          assertFalse blogPost.validate()
          assertEquals 2, blogPost.errors.getErrorCount()
          assertEquals "blank", blogPost.errors.getFieldError("title").getCode()
          assertEquals "blank", blogPost.errors.getFieldError("text").getCode()
