Code Coverage Metrics

Welcome to Luxoft Tech Talks! Click here to listen to the first in this tech talk series: Code Coverage Metrics by Rex Black, President of RBCS.


More and more testers and programmers are using tools that provide code coverage metrics.  These metrics tell the tester or programmer how much of the code has been covered by a given set of tests, and, more importantly, what important conditions might not be covered.  Some tools can also provide insight into the complexity, and thus the likely difficulty level of future refactoring, of the code. 
In this practical presentation, Rex will explain the following code coverage metrics and how you can use them to write better code or tests:

  • Statement, decision, and modified condition/decision  coverage
  • McCabe Cyclomatic Complexity and basis path coverage

To make the material easier to understand and practical, Rex will illustrate each metric using a real program.

Thank you, Karen Cameron, for sharing your team’s feedback and for your endorsement of RBCS training

“I wanted to pass on some feedback from the November Live Virtual CTFL class. Four of my team members attended and all were very impressed with the information presented, how it was presented, and the overall quality of the class. The attendees all stated that the instructor was fantastic and that they hope in 2020 when others from our organization attend training, that the same person is their instructor. I have been a big believer in the courses offered via RBCS since I attended many years ago. Thank you all for having this class available and for continuing to work toward strengthening the QA community at large.”

Did you miss Rex’s November webinar “Is Testing a Waste of Time and Money?”

If so, click here to check it out for free! It won’t be a waste of time!

Is software testing a waste of time and money?  Many people outside of the testing profession seem to think so, and, based on the relative paucity of money devoted to testing compared to other activities in the lifecycle, it’s certainly not a high priority for many organizations.  Is that smart?  Why do we test software?  What benefits, goals, and objectives does testing serve?  Attend this presentation to learn solid, hard-headed, convincing reasons why testing is one of the smartest investments you can make, and why organizations that invest in testing receive long-lasting benefits from doing so.  Rex will lay out the case for software testing and answer your questions.

Test Smarter, Not Harder, with Risk-based Testing

In any real-world project, there are an infinite number of tests you can run, but you don't have forever. This is especially true in Agile, Kanban, CI/CD, and Continuous Deployment projects. How do you decide what to focus on? Risk-based testing, a technique we at RBCS have been perfecting since 1995, is the answer. Risk-based testing allows you answer key testing questions:

- What test conditions should I cover?
- How much effort should I spend on each test condition?
- Which test conditions do I cover first, and which can wait until the end?

In just one week of focused consulting on an actual project, we can show you how to incorporate risk-based testing, using our proven risk-based testing jumpstart technique. Across all types of lifecycles, for over 20 years, we've lead the testing world in defining and applying best practices in risk-based testing. Contact us today.

Test Automation Success

Test automation is great, except when it isn't. And when it isn't great, it can be really, really bad. We've had clients tell us stories of hundreds of thousands, even millions of dollars squandered on test automation efforts that never delivered the expected benefits.

We can help you avoid test automation dysfunction. We have a framework, aligned with the ISTQB Test Automation Engineering model that we use to evaluate test automation strategies and technologies against proven best (and worst) practices. We can also provide expert senior consultants at your location to serve as senior test automation architects, to help you re-direct an under-achieving test automation effort or to launch a new test automation effort in the right direction.

Contact us today to see how we can help you achieve test automation success.
