No , Its related to developer experience

Describe alternatives you've considered

Additional context

Currently test.sh is being used
to run the tests

code-extracter/scripts/test.sh

Lines 46 to 50 in ed66732

	input_file=${root_dir}/temp/src.md
	output_file=${root_dir}/temp/output.md
	lang=python
	echo "[#8] ./main --input ${input_file} --output ${output_file} --lang ${lang}"
	./main --input ${input_file} --output ${output_file} --lang ${lang}

Developer has to manually verify the output dumped onto the terminal,
Wouldn't be better to somehow automate the verification of the results?
