klocwork vs coverity

Static analysis tools like Coverity, Klocwork, Grammatech have good analysis techniques that should produce more accurate results. The tools then read through the code as the compiler would and perform the analysis. So, having tools that automate this analysis and work backward through hundreds of function calls, if need be, to track down a possibly corrupted value is a valuable resource, especially in handling edge cases that might escape typical functional testing. Extensive drill-down capabilities enable managers to view the entire project on one screen or view the status by project components, modules, files, even down to individual lines of code. Stripping out false positives still left K7 ahead in total bug counts. The analysis engine will then comb through the changes and update the defect list, removing references to bugs that have now been remediated. Both tools transcend the traditional concept of static code analysis, so understanding them requires something of a mind shift. This is the path that K7 wisely chose. Whatever differences it comes up with, that's what's new. Hi All, I would like to know if the command line interface version should reflect which version of klocwork i am running on. Our teams get a list of all vulnerabilities and incorporate fixes, ensuring that these issues do not happen in future code. I wonder who has ever compared Klocwork with other open source tools such as Findbugs. Despite these similarities, the products diverged in significant areas. A key differentiator is that K7 can analyze C, C++, and Java, whereas Coverity's product works only on C and C++. Klocwork Static Code Analysis. An important question is, Which approach makes more sense? It has no management console. 1649 Cannot enable... by srikanth.kola@a... 03/04/2019 - 13:39 : No new: User Tools. If I removed those items from the bug counts, the products had comparable defect counts. All e-mails from the system will be sent to this address. Coverity's Unix-like aspect is visible in how it does configuration. Because Coverity is limited to C and C++, it has good representation in embedded contexts. Their results are comparable and this measure should not serve as the primary basis for comparison. They search for functions that are called incorrectly or with invalid values and then report on the specific path through the code that leads to the undesired result. Klocwork is a close second but lacks the same usability in terms of walking developers through the explanation of its finding. Whereas Klocwork K7 provides comprehensive analysis tools and a well-designed set of supporting utilities, Coverity Prevent is a pure analyzer with a simple interface. In addition, I believe Klocwork's approach to bug identification is superior. But beyond the navigational aspects, it can identify odd relationships that would indicate bugs, such as a library of functions making calls to an application -- a definite no-no. Coverity is ranked 11th in Application Security with 8 reviews while Klocwork is ranked 12th in Application Security with 4 reviews. We validate each review for authenticity via cross-reference These are both true enterprise tools, so evaluations should be done with deliberation and careful consultation with sales engineers from the respective vendors. He is a long-time software developer and contributes to open-source projects. 456,495 professionals have used our research since 2012. Both packages are large and have many features, so installation and configuration take time. That is a particular strength of Coverity. An up to date, actively developing product. Fortunately, trial licenses are available along with considerable assistance in performing evaluations.
