![]() When selecting one of these tools, it's VERY important to keep in mind what their licensing model is - typically they determine the price based on the amount of LOC (Lines of Code) that gets "scanned", which can make managing the tool a nightmare. If I could travel back in time and give myself - who was in your position some years ago - just two tips that aren't already mentioned here, they would be: That,s something I’m working to change but C++ tooling is what it is and all of these tools have more robust tooling for other languages.įor C and C++ code, in my experience, CodeSonar and Coverity are in a league of their own, with the next rung down being occupied by Klocwork and lesser known ones like Fortify, Polyspace, etc. In our case it’s pretty well constrained to being a “nightly” operation and not part of our “every commit” CI/CD pipeline. Static analysis with these tools is SLOW for large projects, so be prepared for that. There is a large overlap but each of them has a few things they do better than the others, so running multiple would be best. Usability is good, although I’ve had a harder time breaking builds with it in Jenkins than I would have expected.Īll of these require a central server to be setup, so you should plan for that. Our company already had this setup so we use it for C++code, and I also have no idea what it costs, so can’t comment on whether it’s worth it. It is less of the hard core static analysis where it traces complex control flow and more about finding simple style issues, but some of the rules are important to me (fail on commented out code, for example, a pet peeve of mine). C++support is well behind its support for C#, Java, and JavaScript (only others I have used) but it’s not without merit. Klocwork is easy to integrate and does the same kind of static analysis as coverity. ![]() That is a particular strength of Coverity. Klocwork is a close second but lacks the same usability in terms of walking developers through the explanation of its finding. It also has good compiler support (we used with MSVC and IAR compilers mostly with a few others for various embedded targets thrown in). Coverity is also expensive but worth it for critical or large or aging or complex codebases. if all your tests are automated and you’ll be running them all anyway. Those features are challenging to setup (you can pay their professional services folks for help) and may or may not fit your needs (I.e. Coverity has some advanced features like integrating code coverage and identifying which tests need to be run for a particular code change (tests that cover the modified code as well as tests that cover code that calls into or is called from modified code). The user interface for Coverity is superior. Now that you have a rule set, the next step is to customize the rules by adding or removing rules or modifying the severity of rule violations.Coverity is the best one I’ve seen for C++ in terms of analysis, with Klocwork a close second. You can also enter a description for the rule set. To change the display name of a rule set that's open in the editor, open the Properties window by selecting View > Properties Window on the menu bar. If the rule set includes a child rule set by using an Include tag, and the child and parent rule sets both list the same rule but with different severities, then the severity in the parent rule set takes precedence. ![]() The file does not conform to the rule set schema. If the same rule is listed two or more times in a rule set with the same severity, you may see the following warning in the Error List:ĬA0063 : Failed to load rule set file '.ruleset' or one of its dependent rule set files. ![]() If the same rule is listed two or more times in a rule set with different severities, the compiler generates an error. Select Open to open the new rule set in the rule set editor. The new rule set is selected in the Run this rule set list. In the Add or Remove Rule Sets dialog box, choose the rule sets you want to include in your new rule set. On the Properties pages, select the Code Analysis tab. In Solution Explorer, right-click the project and then select Properties. NET Standard projects, which don't support the same features in the Code Analysis property tab. The following procedure does not apply to. ![]()
