How can I debug failed tests in my C++ project?

Start by checking the error messages in your test output. They often provide clues about what went wrong.

I see a segmentation fault error. What does that mean?

A segmentation fault usually indicates that your code is trying to access memory that it shouldn't. Check for null pointers or out-of-bounds array access.

How can I find where the segmentation fault is occurring?

You can use a debugger like gdb. Run your program with gdb, and when it crashes, use the 'backtrace' command to see the call stack.

Are there any tools that can help automate this process?

Yes, tools like Valgrind can help detect memory issues and provide detailed reports on memory usage.
