It seems like you are missing the Xdebug extension. If you’re using homebrew you can install it like: brew install php70-xdebug After that, don’t forget to edit your php.ini file to enable the extension. php -i | grep xdebug After checking that xdebug is enabled you should be able to do code coverage
You can also install lcov and convert the lcov.info file to HTML pages and then see the result in the browser with sorting option. 1. Installation 1.1. Installing in Ubuntu sudo apt-get update -qq -y sudo apt-get install lcov -y 1.2. Installing in Mac brew install lcov 2. Run tests, generate coverage files and convert … Read more
A branch is where the runtime can choose whether it can take one path or another. Lets take the following example: if(a) { Foo(); } if(b) { Bar(); } Yay(); When reaching the first line, it can decide if it wants to go inside the body of the if(a)-statement. Also, it can decide not to … Read more
It took me a while and it also took me taking small snippets from a number of different sources and melting them together, but I think I have a small working example that sufficiently demonstrates to a Perl newbie the Perl build process including unit testing and code coverage analysis & reporting. (I’m using ActiveState … Read more

For static analysis tools I often use CPD, PMD, FindBugs, and Checkstyle. CPD is the PMD “Copy/Paste Detector” tool. I was using PMD for a little while before I noticed the “Finding Duplicated Code” link on the PMD web page. I’d like to point out that these tools can sometimes be extended beyond their “out-of-the-box” … Read more
I don’t entirely agree with Jon Skeet. I think that if you can get an easy win to give you coverage and eliminate the noise in your coverage report, then you should do it. Either tell your coverage tool to ignore the constructor, or put the idealism aside and write the following test and be … Read more
