The particular programming language you use for your test framework does not matter. Execution efficiency of the framework is not likely to be a problem. A carefully designed test framework that manages the board testing in an automated fashion does. Thinking through and formalizing the testing process (and the analysis to test results) will be much more fruitful than worrying about whether to program the framework in BASH, Python, Golang, or LISP.
