What are assertions in C++ testing?

What are assertions in C++ testing?

Assertions in C++ testing are statements that check if a condition is true during program execution. If the condition is false, the program will terminate, helping to identify bugs early.

How do I implement assertions in my C++ code?

You can use the <cassert> header and the assert() macro. For example, assert(x > 0); will check if x is greater than 0.

Can assertions be disabled in release builds?

Yes, assertions can be disabled by defining the NDEBUG macro before including <cassert>. This will prevent assertions from being checked in release builds.

What are some best practices for using assertions?

Best practices include using assertions to check for conditions that should never happen, avoiding side effects in assertions, and using them for debugging rather than error handling.
