Practical Software Testing Resources?

rhartness asks: "I've been a software engineer by profession for a few years and a programming enthusiast for much longer. As my experience has increased, so has the size of the projects that I have had to work on. My software testing method involves trying to do everything I can think of that the end user might try to do. Hopefully, this will break the application if there is a bug within my code. The current project that I am working on involves numerous tiers within a smart client environment. Trial and error testing is no longer sufficient — there is simply too much that could happen. Searching the Internet for software testing resources provides an abundant amount of information but it's often quite philosophical and verbose. What are some practical resources that Slashdot readers use for testing your software projects?"

First, understand testing

Read "The Art of Software Testing" by Glenford Myers. Even if you only get a few chapters in, you'll get a lot of ideas that will improve your testing. "Testing Computer Software" by Cem Kaner is another good one.

Automate, automate, automate.

Step 1: write a systematic test plan. There are all kinds of acronyms and books out there on the subject - I doubt you need it. At the very least you can start with CRUD (Create, Read, Update, Delete) and go from there. Cover the success path, cover the failure paths.

Step 2: automate. This isn't optional if you're planning to maintain a project beyond the 1.0 release. For specifics, it depends on your project. Is it mostly a Java app (http://www.junit.org/)? Is a lot of the logic in the database (http://www.dbunit.org/)? Is it a web app, regardless of language (http://webtest.canoo.com, http://wtr.rubyforge.org/)?

Step 3: run your automated tests and laugh at how much easier it makes your life than manual testing.
