#20311 Running Python test under pyinstrument or other custom executable New discussion created by eguiraud Hello, I have some Python tests (typically run with

pants test ...

) that I sometimes would like to run under a profiler such as

pyinstrument

, or

cProfile

, and some other times even under a C/C++ debugger like

gdb

in order to break into problematic logic in a given extension module. What is the simplest way to do so? What I am doing at the moment: • change

BUILD.pants

file to add a

pex_binary

rule for the

python_test

rule that I want to instrument/debug • change the test to make it run the test what it's run as a standalone Python executable by adding an invocation to the test function under

if __name__ == "__main__"

• run

pants package

for the

pex_binary

target •

gdb --args python ./dist/path/to/target.pex

now seems to work pantsbuild/pants
