Pablo: to run the friendly-traceback test suite is simply a matter of typing
"pytest" from the root directory of the repository (after installing the
dependencies). However, it would not be helpful for the purpose of CPython
development, as likely more failing tests would be due to Friendly-traceback
itself.
As a first step, Friendly-traceback tries to make use of the information given
by Python (for example, the new "expected ':'"); if it does not recognize the
message, or if the message is "invalid syntax", it uses some heuristics to
guess what might be the probable cause.
Improvements to the messages given by CPython are likely going to initially
result in failed tests for Friendly-traceback, whether the information provided
by CPython is valid (most of the time) or not.
The test suite I use includes things that I imagine a beginner might write. For
example, using "else if" instead of "elif". With one of the newest additions
of CPython ("expected ':'") which is accurate in most cases, this specific unit
test would likely fail until I make the appropriate adjustement to
Friendly-traceback.
