Stress tests force programs to operate under limited resource conditions. The goal is to push the upper functional limits of a program to ensure that it can function correctly and handle error conditions gracefully.

If other memory-oriented tests are also planned, they should be performed here as part of the stress test suite. Stress tests can be automated
