As patient care continues to evolve, IT teams have accelerated this shift from legacy, on-premises systems to cloud technology to more build, test, and deploy software, and fuel healthcare innovation. Amid so much change, teams can no longer rely on time-consuming, manual approaches for building, testing, operating, and upgrading software.

Basis path testing in software testing is a white box method where the tester examines the codebase to identify all possible paths that could be taken by the user to achieve their aims. These paths are then written as test cases to ensure all the different identified scenarios in the main branches are covered.

There is a decades-long tradition of data-centric programming : developers who have been using data-centric IDEs, such as RStudio, Matlab, Jupyter Notebooks, or even Excel to model complex real-world phenomena, should find this paradigm familiar. This approach is not novel. Two important trends collide in these lists.

Tech pundits still seem to commonly assume that UB is so fundamentally entangled in C++s specification and programs that C++ will never be able to address enough UB to really matter. Background in a nutshell: In C++, code that (usually accidentally) exercises UB is the primary root cause of our memory safety and security vulnerability issues.

An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work.

This was no small task given the mismatch between a fine granularity of rules on the one hand and a coarse granularity of test cases on the other.

It’s also awkward, an exercise of the blindfolded people describing the pachyderm.
