Explain testing strategies and unit testing in MATLAB

MATLAB testing strategies involve automated validation using unit tests, integration tests, regression tests, and continuous integration pipelines.

Testing is critical in scientific computing and enterprise software because numerical errors can produce catastrophic consequences in engineering, healthcare, aerospace, and finance.

MATLAB provides the matlab.unittest framework for automated software testing.

Testing strategies generally include:

Tests individual functions or classes.

Verifies interactions between components.

Ensures new changes do not break existing functionality.

Measures execution speed and scalability.
