Guidelines and HOWTOs/Code Checking
Code Checking
There are a lot of ways to find bugs in KDE code. Increasingly, KDE developers have started to use automated tools. You can use some of those tools to improve your own code.
The KDE 'Krazy' Checker
KDE developers have a simple set of tests that are collectively known as "Krazy".
Compiler Warnings
In addition to the various Krazy tools, you can also get valuable assistance from the warnings that the compiler emits, especially if you enable additional warnings (per the documentation for your compiler), and also if you test with more than one compiler (e.g. if you can test on Linux with both GCC and the Intel compiler; or on Linux with GCC and also on Windows with the Microsoft compiler).
