z2-Environment

Bug #1946

Updated by Udo Offermann over 8 years ago

.h2 Problem 

 create a z2 unit test containing a private method with an @Test annotation. 
 org.junit.runners.ParentRunner will detect that this is an error and throws an InitializationError containing all violations: 

 <pre> 
     // inside indside ParentRunner 

     private void validate() throws InitializationError { 
         List<Throwable> errors = new ArrayList<Throwable>(); 
         collectInitializationErrors(errors); 
         if (!errors.isEmpty()) { 
             throw new InitializationError(errors); 
         } 
     } 
 </pre> 

 Z2UnitTestRunner now catches all Exceptions and wraps them within a new @InitializationError@ so that the violations are hidden. 

 h2. Suggestion 

 rewrite  

 <pre> 
	 public Z2UnitTestRunner(Class<?> klass) throws InitializationError { 
		 this.clz = klass; 
		 this.readConfig(); 
		 try { 
			 if (this.runWithClass!=Runner.class) { 
				 this.runWith = this.runWithClass.getConstructor(Class.class).newInstance(this.clz); 
			 } else { 
				 this.runWith = new BlockJUnit4ClassRunner(this.clz); 
			 } 

                 } catch (InitializationError e) { 
                         // InitializationError must not be wrapped! 
                         throw e; 

		 } catch (Exception e) { 
			 throw new InitializationError(e); 
		 } 
	 } 

 </pre>
