While you are trying to buy this ebook, and also you are within the yr 2010 or past, don't buy THIS ebook. Please proceed analyzing my evaluate less than, besides the fact that, to appreciate why.
This booklet is outmoded because:
1. It has super precise directions for utilizing eclipse (the IDE) with pydev, mylyn, and pydev-extensions. Eclipse has replaced much when you consider that this e-book was once written, and the directions aren't any longer actual. The pydev-extensions plugin does not really exist anymore, it was once merged with pydev. this is often complicated for brand spanking new clients attempting to get issues running.
2. The directions for purchasing buildbot working aren't any longer right. Buildbot has replaced a section in addition, and the main points for install is assorted than it used to be.
3. It spends some time conversing approximately pMock, certainly one of 2 python mock libraries, which hasn't been constructed considering that 2004 and is taken into account obsolete.
4. It spends your time conversing approximately pyfit, which hasn't been labored on considering the fact that 2006 and can also be now not as a rule used.
Now, for my innovations in regards to the ebook itself:
I made up our minds to provide this ebook a five celebrity evaluation since it is a superb book:
- the writer writes super good, and has slightly humor in the course of the book.
- the writer covers extensions why TDD is sweet, the way it is helping, and the way it's going to be used.
- the writer describes the differing kinds of checking out, and offers transparent, intuitive, and considerate examples that basically exhibit *how to* do the testing.
- the writer covers super distinctive setup / install / configuration of the instruments and improvement environments discussed.
The it's because i must now not suggest any readers buy this e-book notwithstanding, is that it really is sorely wanting an replace. I simply accomplished interpreting this e-book (August, 2010), and it's very transparent that it truly is superseded. This e-book may were super invaluable years in the past, and perhaps additionally the 1st area of 2009, yet agile practices and instruments have replaced lots for the reason that then that this ebook fairly has to be rewritten.
My suggestion to readers who're contemplating procuring this publication is to take action provided that you're conscious of what you may be getting, yet wish to utilize the author's code examples, writing, and TDD causes whereas brushing off the instruments used.
I fairly did take pleasure in studying this booklet, even though, and that i relatively desire that Apress forces Jeff to free up a brand new reproduction.

Example text
It focuses on changes that alter the structure of the code without altering the meaning. I find refactoring quite fun, but it’s dangerous if you don’t have unit tests in place. Without unit tests, you don’t know if you’ve unintentionally altered the meaning. In some sense, refactoring is one of the most well-understood areas of software development. It is described extensively in the literature. Refactorings have names and precise definitions. Some refactorings are done with an eye to improving readability, some are done with an eye toward removing redundancy and duplication (known to some as “the death of code”), and some are done to improve modularity.
The build system should check out a clean copy from revision control, and then build from it. This ensures that the build does not depend on previously generated artifacts, and it tests that the build can be done on a machine other than the developer’s desktop. This also goes a long way to ensuring that any developer can sync the code tree down to a new machine, issue a single build command, and have the build succeed. This allows desktops to be replaced quickly in case of failure, and it helps new developers on a project to come up to speed quickly.
