Advanced Zig Unit Testing Debugging: Combining Print Debugging and the Debugger

This article presents techniques to enhance Zig unit test debugging, combining print debugging and the debugger. The author first addresses the issue of verbose print debugging output by using `errdefer` to print only when a test fails, reducing clutter. Then, the `build.zig` script is leveraged to run the debugger during the build process, simplifying debugging of test binaries. Finally, conditional compilation, combined with the build option `-Ddebugger`, allows enabling debugger breakpoints only when needed, avoiding debugger interference during normal test runs. This approach significantly improves Zig unit test debugging efficiency.
