jmock

I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and

I have classes which previously had massive methods so I subdivided the work of this method into 'helper' methods. These helper methods are declared private to enforce encapsulation - however I want to unit test the big public methods. Is it good to unit test the helper methods too as if one of them fail the public method that calls it will also fail, and this way we can identify why it failed? Also in order to test these using a mock object I would need to change their visibility from private to protected, is this desirable? One way is to omit private and put the tests in the same package.

I'm using JMock to test the behavior of a class using an object. I want to test that the method a() is called. However, b() and c() also are called on the object too. Therefore if my expectations expect a() , it must also expect b() and c() to make the test pass. Is there a way to test only for a certain method, and allow anything else? Michael Barker Expect a() allow only methods b() & c() mockery.checking(new Expectations() {{ one(mockObject).a(); allowing(mockObject).b(); allowing(mockObject).c(); }}); Expect a() allow all other methods. mockery.checking(new Expectations() {{ one(mockObject

With JMock: context.checking(new Expectations() {{ // Other oneOf() will() statements ... oneOf(shopAccount).enter(100, with(any(String.class))); will(returnValue(true)); // Other oneOf() will() statements ... }}); The following exception will be raised during execution: java.lang.IllegalArgumentException: not all parameters were given explicit matchers: either all parameters must be specified by matchers or all must be specified by values, you cannot mix matchers and values. Why i cannot do this way? using with(any(Klass.class)) ? Steve Freeman if you use a with clause for any parameter, you
