Coverage is a subtle 😉 mix of the line and the branch coverage. You can find the formula on our metric description page: coverage = (CT + CF + LC)/(2*B + EL) where CT – branches that evaluated to “true” at least once CF – branches that evaluated to “false” at least once LC – … Read more
I used the –no-external flag together with the –directory flag to exclude unwanted files. The definition of external from the man: External source files are files which are not located in one of the directories specified by –directory or –base-directory. So my command looked like this: $ lcov –directory src -c -o report.info –no-external Capturing … Read more
A tale from personal experience. Apologies for the length. A few years ago our development group tried setting “proper” measurable objectives for individuals and team leaders. The experiment lasted for just one year, because hard metrics didn’t really work very well for individual objectives (see my question on the subject for some links and further … Read more
The answer by Paul isn’t quite right, at least I think so (according to ISTQB’s definitions). There’s quite significant difference between statement, decision/branch and condition coverage. I’ll use the sample from the other answer but modified a bit, so I can show all three test coverage examples. Tests written here gives 100% test coverage for … Read more
I had same problem using maven cobertura plugin. All tests failed when run from cobertura:report. But all tests succeeded when run directly from surefire plugin. As some of you already said the problem is that coberture byte code instrumentation of is not compatible with JDK7. You can see here http://vikashazrati.wordpress.com/2011/10/09/quicktip-verifyerror-with-jdk-7/ that the exception is related … Read more
Here’s a technical paper on How to Implement test coverage tools for arbitrary languages. My company builds a family of test coverage tools for Java, C#, C++, PHP, COBOL, PLSQL, … based on this principle.
It works. (function(global) { var defineAsGlobal = true; /* istanbul ignore next */ if(typeof exports === ‘object’) { module.exports = lib; defineAsGlobal = false; } /* istanbul ignore next */ if(typeof modules === ‘object’ && typeof modules.define === ‘function’) { modules.define(‘lib’, function(provide) { provide(lib); }); defineAsGlobal = false; } /* istanbul ignore next */ if(typeof … Read more
