... David Saff ... [snip] ... Cedric, I've been telling you this for a year or so... Tests get instantiated at the start (one instance per test), they are run,...
... Correction: you don't have to maintain state across methods. Because each test is in its instance, there is no possibility of having the state modified. ...
hello group, When i was unit testing my SAX parser implementation to parse my xml file, i faced one problem. i want to test the startElement(...) method of the...

... It the code isn't tested through the public (or protected) then you aren't testing it in the context in which it will actually be used. Private methods are...

... It is certainly possible to test private methods, but I prefer not to do it. I prefer to make the method public, test it, then figure out why it was...

hi lets assume class is SimpleMathTest.class and resides at c:java\bin try at console following command c:\java\bin\java -cp c:java\bin; SimpleMathTest why is...
Hi. I have implemented an algorithm in Java which produces state cover, shortest paths to get another statefrom start state, from a finite state machine(FSM)....
... Nice. After thinking about it for awhile, here are some things I think could be done (in order) before making private methods public for testing when you...
Actually, if you were really following TDD then you wouldn't have the private method unless it was already covered by tests. At least that's the methodology I...
The formula works like this (it doesn't really matter what your code actually does). Your library/algorithm takes some input and produces some output. Your...
... I don't see this as a solution. If the method wasn't public before, it shouldn't be public now just because it moved to a different class. If the only...

... If using TDD you are slowly emerging the design. Why would Extract Class not be a valid refactoring? At some point a private method on a class wants to be...

... Elliotte, I agree that privates should be kept private, encapsulation should not be broken for the purpose of testing, and that the number of messages in...
... If extracting a class causes a method to become public that otherwise wouldn't be public, then it's a problem. Public APIs are rigid and inflexible. Public...

Certainly. My point (which came out wrong) was that if the class was written test-first then I wouldn't feel like I needed to use a coverage tool to be sure...
Hi. David. Yeah, Could you give me some more details where I can get the examples and how to test them? Or any web materials. Thanks a lot. Regards,...
Hi Jin, I am not David, but I want to make a comment. David provided a general recipe for testing algorithms. Since you are designer of the algorithm, at the...
