Software Testing Errors to look out for (with examples)

Testsigma

It occurs when the arithmetic calculation results in a value that is way too large for the software program to handle. The impossible values should be identified and removed from the program, otherwise, they will result in error conditions. Hardware error. We focus on software so much that we forget about the hardware failures.

Architectural Myopia

ACM Sigarch

It is much more difficult to publish truly risky, revolutionary research due to implicit filters in what gets funded and what makes it past a program committee. According to the article “ When Women Stopped Coding “, the percent of women in Computer Science 30 years ago was nearly twice what it is now. Discounting the Past.

The Return of the Frame Pointers

Brendan Gregg

Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken. Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway.
