Testing the entire integrated system at once after all modules are completed.

In Big Bang testing, no integration is verified until everything is developed. It’s simple to plan but risky because issues are harder to trace when discovered late.

This method suits small projects with minimal dependencies but leads to major debugging challenges in large systems, especially if integration defects pile up.
