Coverage is the degree, expressed as a percentage, to which a specified dimension of coverage has been exercised by your tests. Typical dimensions of coverage are requirements, risks, supported configurations, role-based security, and user personas, among others.


Resources for “Coverage”

Articles

When I talk to senior project and product stakeholders outside of test teams, confidence in the system—especially, confidence that it will have a sufficient level of quality—is one benefit they want from a test team involved in system and system integration testing. Another key benefit such stakeholders commonly mention is providing timely, credible information about quality, including our level of confidence in system quality. 

Reporting their level of confidence in system quality often proves difficult to many testers. Some testers resort to reporting confidence in terms of their gut feel. Next to major functional areas, they draw smiley faces and frowny faces on a whiteboard, and say things like, “I’ve got a bad feeling about function XYZ.” When management decides to release the product anyway, the hapless testers either suffer the Curse of Cassandra if function XYZ fails in production, or watch their credibility evaporate if there are no problems with function XYZ in production.

"Back in 2010, at the launch of Core Magazine, http://www.coremag.eu/, I wrote a series of columns to welcome people to the magazine. As a sort of Throw-Back-December, here they are, as they appeared in the original magazine issues. I hope you enjoy them."
-Rex Black
 
Greetings, and welcome to my quarterly column on software testing best practices.  When I was asked to write this column, I had to choose the approach, the theme.  The writers' aphorism says, "Write what you know." So, what do I know?
 
Well, if you know me and my consulting company, RBCS, you know that we spend time with clients around the world, in every possible industry, helping people improve their testing with training or consulting services, or doing testing for them with our outsourcing services.  Our work gives me insights into what goes on, the actual day-to-day practice of software testing.

Webinar: Dimensions in Test Coverage: 3/12/13


Length: 1h 27m 35s

You hear people talk about “coverage” a lot in testing, but what exactly do they mean? Three different people could mean three—or more—different things when they use this word. It’s not that those different meanings are wrong, they’re just—different. Test coverage is a powerful and important topic, and it’s time we all got clear on what it means and how to use it. So, in this free webinar, Rex will explore the various dimensions of test coverage and how you can make those dimensions work for you on your next testing project.

One Key Idea: Pairwise Testing Using ACTS 2/16/17


Length: 0h 38m 45s

If you’ve been testing for any length of time, you know that the number of possible test cases is enormous if you try to test all possible combinations of inputs, configuration values, types of data, and so forth. It’s like the mythical monster, the many-headed Hydra, which would sprout two or more new heads for each head that was cut off. Two simple approaches to dealing with combinatorial explosions such as this are equivalence partitioning and boundary value analysis, but those techniques don’t check for interactions between factors. A reasonable, manageable way to test combinations is called pairwise testing, but to do it you’ll need a tool.  In this inaugural One Key Idea session, Rex will demonstrate the use of a free tool, ACTS, built by the US NIST and available for download worldwide. We can’t promise to turn you into Hercules, but you will definitely walk away able to slay the combinatorial Hydra.
