Java programmer here. That's ok. Python is a good language, and it is especially good for learning environments. Java is heavy -- the smallest possible "Hello, world" program in Java is five lines -- and it tends to force con

I have a better idea. Make it so that some traffic receives higher priority than others, and force content providers to have to pay to play. Then limit competition at the ISP level so that to succeed you have to pay a monopoly to carry your

Cute, but even as terse as this comment is its sentiment is incorrect. Mocks, almost by their very nature, encourage coupling. Ask yourself the question "What tends to get mocked? " Answer: Objects which are difficult and/or

Dependency injection has seen its day. The gains promised by DI/IoC containers tend to be outweighed by the complexity they introduce. I'm looking at you, Spring.

How is that a burden? The controller has to know about the methods of the DAO no matter what. The debate you're having seems to be "what is the best way to get a concrete instance of the DAO into the controller?" The argument

This has been my experience as well. The core of Spring -- IoC/DI -- solves a problem that is largely of its own making. I've had better luck and cleaner code without it than with it.

That wasn't the central premise. The central premise is that there is a trade-off in class design when doing unit testing.

Let's take as an example dependency injection. The genesis for DI was to facilitate the testing of objects that are dependent on objects that are not easily constructed, such as DAOs. And the whole reason this was done was so that thes

The point of unit testing, or any testing, is to make sure that the code does what it should. Public vs. private interfaces are philosophical distinctions in determining what is a "proper" unit test, and do not help in validating

This... is not Kent's finest moment. I get what he's saying, but the snark doesn't really help, and doesn't actually rebut any of the points that DHH was making against TDD. Testing does tend to have a negative impact

by revscat 13y ago
In Java, the most obvious example of testing affecting the design of a class is the necessity of avoiding private methods in order to facilitate testing. While there are ways around this -- reflection, PowerMock, probably others -- they all

It is executing shell commands based on what you pass in through a request parameter. Since there is no filtering going on, you could, I suppose, pass in an entire bash script and have a good ol' time.

The linked article does not support your assertion. It speaks to being careful not to overuse mocks, but does not state that mocks are inherently distrustful. If anything, it implies the opposite since it is saying "here are some thing
