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.

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.

That’s true whether we’re enabling checking at test time (e.g., Some conditions are so expensive that we may never check them without a good reason, even in testing.

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. The rules were implemented as IFTTT statements in a low-code language that did not allow them to be tested in isolation. In just about every circumstance, it was false results.

It’s also awkward, an exercise of the blindfolded people describing the pachyderm. Some of this is likely a function of professional programming: if, for the totality of your career, the boss has supplied you with the reason why you do the things that you do, it isn’t natural to start a new initiative by asking “why”.
