What is ‘good code’?
‘Good code’ is code that works, is bug free, and is readable and maintainable. Some organizations have coding ’standards’ that all developers are supposed to adhere to, but everyone has different ideas about what’s best, or what is too many or too few rules. There are also various theories and metrics, such [...]
What kinds of testing should be considered?
‘ Black box testing – not based on any knowledge of internal design or code. Tests are based on requirements and functionality’.
‘White box testing – based on knowledge of the internal logic of an application’s code. Tests are based on coverage of code statements, branches, paths, conditions’.
‘unit testing – [...]

Why is it often hard for management to get serious about quality assurance?
Solving problems is a high-visibility process; preventing problems is low-visibility. This is illustrated by an old parable:
In ancient China there was a family of healers, one of whom was known throughout the land and employed as a physician to a great lord. The [...]
What is ‘Software Quality Assurance’?

It is oriented to ‘prevention’. (See the Bookstore section’s ‘Software QA’ category for a list of useful books [...]
How can World Wide Web sites be tested?
Web sites are essentially client/server applications – with web servers and ‘browser’ clients. Consideration should be given to the interactions between html pages, TCP/IP communications, Internet connections, firewalls, applications that run in web pages (such as applets, javascript, plug-in applications), and applications that run on the server side [...]
What if the project isn’t big enough to justify extensive testing?
Consider the impact of project errors, not the size of the project. However, if extensive testing is still not justified, risk analysis is again needed and the same considerations as described previously in ‘What if there isn’t enough time for thorough testing?’ apply. The tester [...]
What is ‘configuration management’?
Configuration management covers the processes used to control, coordinate, and track: code, requirements, documentation, problems, change requests, designs, tools/compilers/libraries/patches, changes made to them, and who makes the changes. (See the ‘Tools’ section for web resources with listings of configuration management tools. Also see the Bookstore section’s ‘Configuration Management’ category for useful books [...]
What’s a ‘test plan’?
A software project test plan is a document that describes the objectives, scope, approach, and focus of a software testing effort. The process of preparing a test plan is a useful way to think through the efforts needed to validate the acceptability of a software product. The completed document will help people [...]
What makes a good test engineer?
