Static analysis tools. For instance, clang analyzer. See https://en.wikipedia.org/wiki/List_of_tools_for_static_code_analysis These tools parse all the code to produce some sort of model and then do lots of 'what-if' analysis on all code paths. Advantages: does not depend on your test coverage, can check for very many kinds of errors. Disadvantages: tools have to make tradeoffs between runtime and really checking all possibilities. Also the models are usually limited in scope which can cause false positives. 2. Dynamic analysis tools like Valgrind. Again wikipedia has a page listing tools https://en.wikipedia.org/wiki/Dynamic_program_analysis These tools test running code. Advantages: lower rate of false positives. Disadvantage. Only as good as your tests - you should be measuring your code coverage! Performance - usually there is a large memory and/or runtime overhead, which can make running dynamic tools on large applications/data imprectical.
