I was vaguely annoyed to see this blog article Buy protonix without prescription, featured in JavaLobby's recent mailout. Not because Kevin Pang doesn't make some good points about the limits of code coverage, Protonix tablets, but because his title is needlessly controversial. And, because JavaLobby is engaging in some agile-baiting by publishing it without some editorial restraint.

In asking the question, cheap protonix on internet, "Is code coverage all that useful, Find protonix, " he asserts at the beginning of his article that Test Driven Development (TDD) proponents "often tend to push code coverage as a useful metric for gauging how well tested an application is." This statement is true, but the remainder of the blog post takes apart code coverage as a valid "one true metric," a claim that TDD proponents don't make, buy protonix, except in Kevin's interpretation.

He further asserts that "100% code coverage has long been the ultimate goal of testing fanatics." This isn't true. Online protonix, High code coverage is a desired attribute of a well tested system, but the goal is to have a fully and sufficiently tested system. Code coverage is indicative, protonix online sale, but not proof, Order cheap protonix online, of a well-tested system. How do I mean that, buy protonix without prescription. Any system whose authors have taken the time to sufficiently test it such that it gets > 95% code coverage is likely (in my experience) thinking through how to test their system in order to fully express its happy paths, edge cases, order protonix in us, etc. Find discount protonix, However, the code coverage here is a symptom, not a cause, cheapest protonix prices, of a well-tested system. Cheap protonix no rx, And the metric can be gamed. Actually, when imposed as a management quality criterion, order protonix from canada, it usually is gamed. Buy protonix without prescription, Good metrics should confirm a result obtained by other means, or provide leading indicators. Protonix cheapest price, Few numeric measurements are subtle enough to really drive system development.

Having said that, I have used code-coverage in this way, but in context, cheapest generic protonix online, as I'll mention later in this post.

Kevin provides example code similar to the following:

String foo(boolean condition) {    if (condition)        return "true";    else        return "false";}

... Cheap protonix from usa, and talks about how if the unit tests are only testing the true path, then this is only working on 50% coverage. Good so far, protonix prices. But then he goes on to express that "code coverage only tells us what was executed by our unit tests, Cheap protonix overnight delivery, not what executed correctly." He is carefully telling us that a unit test executing a line doesn't guarantee that the line is working as intended. Um.., buy protonix without prescription. that's obvious. And if the tests didn't pass correctly, buy protonix no rx, then the line should not be considered covered. Buy protonix on line, It seems there are some unclear assumptions on how testing needs to work, so let me get some assertions out of the way...

Code coverage is only meaningful in the context of well-written tests. It doesn't save you from crappy tests.

Code coverage should only be measured on a line/branch if the covering tests are passing.

Code coverage suggests insufficiency, purchase protonix no rx, but doesn't guarantee sufficiency.

Test-driven code will likely have the symptom of nearly perfect coverage.

Test-driven code will be sufficiently tested, Protonix rx, because the author wrote all the tests that form, in full, the requirements/spec of that code.

Perfectly covered code will not necessarily be sufficiently tested.

What I'm driving at is that Kevin is arguing against something entirely different than that which TDD proponents argue, order no rx protonix. Buy protonix without prescription, He's arguing against a common misunderstanding of how TDD works. On point 1 he and I are in agreement. Order cheap protonix, Many of his commentators mention #3 (and he states it in various ways himself). His description of what code coverage doesn't give you is absurd when you take #2 into account (we assume that a line of covered code is only covered if the covering test is passing). But most importantly - "TDD proponents" would, generic protonix cheap, in my experience, Fda approved protonix, find this whole line of explanation rather irrelevant, as it is an argument against code-coverage as a single metric for code quality, and they would attempt to achieve code quality through thoroughness of testing by driving the development through tests, where to order protonix. TDD is a design methodology, not a testing methodology, buy protonix without prescription. You just get tests as side-effect artifacts of the approach. Protonix without prescription, Useful in their own right. Sure, but it's only sort of the point, buy protonix online australia. It isn't just writing the tests-first.

In other words - TDD implies high or perfect coverage. But the inverse is not necessarily true.

Buy protonix without prescription, How do you achieve thoroughness by driving your development with tests. Buying protonix online, You imagine the functionality you need next (your next increment of useful change), and you write or modify your tests to "require" the new piece of functionality. They you write it, generic protonix, then you go green. Order generic protonix, Code coverage doesn't enter into it, because you should have near perfect coverage at all times by implication, because every new piece of functionality you develop is preceded by tests which test its main paths and error states, protonix india, upper and lower bounds, Cheap protonix online, etc. Code coverage in this model is a great way to notice that you screwed up and missed something, but nothing else.

So, cheap protonix in canada, is code-coverage useful. Heck yeah, buy protonix without prescription. No prescription protonix, I've used coverage to discover lots of waste in my system. I've removed whole sets of APIs that were "just in case I need them" APIs, because they become rote (lots of accessors/mutators that are not called in normal operations), protonix in uk. Is code coverage the only way I would find them. Certified protonix, No. Buy protonix without prescription, If I'm dealing with a system that wasn't driven with tests, or was poorly tested in general, I may use coverage as a quick health meter, but probably not. Going from zero to 90% on legacy code is likely to be less valuable than just re-writing whole subsystems using TDD... and often more expensive.

Regardless, cheap protonix tablets, while Kevin is formally asking "is code coverage useful?" he's really asking (rhetorically) is it reasonable to worship code coverage as the primary metric. Protonix without a prescription, But if no one's asserting the positive, why is he questioning it. He may be dealing with a lot of people with misunderstandings of how TDD works, lowest price protonix. He could be dealing with metrics bigots, buy protonix without prescription. He could be dealing with management-imposed-metrics initiatives which often fail. It might be a pet peeve or he's annoyed with TDD and this is a great way to do some agile-baiting of his own. I don't know him, so I can't say. His comments seem reasonable, so I assume no ill intent. But the answer to his rhetorical question is "yes, but in context." Not surprising, since most rhetorically asked questions are answerable in this fashion. Hopefully it's a bit clearer where it's useful (and where/how) it's not.

Buy zofran without prescription, This post is a little geeky and technical and product-related for AgileAdvice, and is a shameless self-promotion. Cheap zofran pill, Nevertheless, since testability, find discount zofran online, Buy zofran, test-driven-development, and incremental design are non-exclusive sub-topics of Agile, zofran sale, Buy cheap zofran, I though I'd report this here anyway.

Many developers use the Dependency Injection and Inversion of Control (IoC) patterns through such IoC containers as Spring, Hivemind, zofran online cheap, Zofran information, Picocontainer, and others, find cheap zofran online. Buy zofran us, They have all sorts of benefits to testability, flexibility, buy zofran in us, Zofran online, etc. that I won't repeat here, cheap zofran in uk, Zofran online review, but can be read about here, here, zofran purchase, Pharmacy zofran, and here. A great summary of the history of "IoC" can be found here, cheapest zofran price. J2ME developers, however, especially those on limited devices that use the CLDC configuration of J2ME, cannot use the substantial number of IoC/DI containers out there, because they nearly all rely on reflection, buy zofran without prescription. Zofran approved, These also often make use of APIs not present in the CLDC - APIs which could not easily be added. Lastly there's a tendency among developers of "embedded software" to be very suspicious of complexity.

In working out some examples of DI as part of a testability workshop at one of my clients, order zofran no prescription required, Buy cheap zofran internet, I whipped up a quick DI container, and being the freak that I am, no rx zofran, Zofran without a prescription, hardened it until it was suitable for production, because I hate half-finished products, purchase zofran overnight delivery. Buy zofran no prescription required, So allow me to introduce the Israfil Micro Container. (That is, find discount zofran, Buy zofran generic, the Container from the Israfil Micro project). Buy zofran without prescription, As I mention in the docs, "FemtoContainer" just was too ridiculous, and this container is smaller than pico-container. The project is BSD licensed, order zofran from us, Compare zofran prices, and hosted on googlecode, so source is freely available and there's an issue/feature tracker, generic zofran, Buy zofran from us, yadda yadda.

Essentially I believe that people working on cellphones and set-top boxes shouldn't be constrained out of some basic software design approaches - you just have to bend the design approach to fit the environment. So hopefully this is of use to more than one of my clients, where to buy zofran. Zofran cheap, It currently supports an auto-wiring registration, delayed object creation (until first need), overnight zofran, Order zofran from canada, and forthcoming are some basic lifecycle support, and a few other nicities, zofran overnight shipping. Buy zofran online australia, It does not use reflection (you use a little adapter for object creation instead), and performs quicker than pico-container, buy zofran no rx. Low, low overhead, buy zofran without prescription. Order zofran on internet, It's also less than 10 classes and interfaces (including the two classes in the util project). It's built with Maven2, cheap zofran no rx, Zofran india, so you can use it in any Maven2-built project with ease, but of course you can always also just download the jar (and the required util jar too), cost zofran. Enjoy...

P.S. There are a few other bits on googlecode that I'm working on in the micro-zone. Some minimalist backports of some of java.lang.concurrency (just the locks), as well as some of the java.util.Collections stuff. Not finished, but also part of the googlecode project.
