New issue 290: Display exit code with InvocationErrors https://bitbucket.org/hpk42/tox/issues/290/display-exit-code-with-invocationerrors
Daniel Hahler: When a command fails, you currently only get `ERROR: InvocationError: '/usr/bin/false'`, but the exitcode itself is useful/important, e.g. with py.test using 5 for "no tests collected". The following patch would provide that, by using a custom `__str__` method for InvocationError - but it does not handle the case where that might be missing (not all instances / calls to it provide it). Maybe a custom `__init__` should be used to set the arguments as properties explicitly, and then use them?! ``` diff -r e9569646da4f tox/__init__.py --- a/tox/__init__.py Wed Nov 25 12:27:48 2015 +0100 +++ b/tox/__init__.py Wed Nov 25 13:23:26 2015 +0100 @@ -17,6 +17,9 @@ "signals that an interpreter could not be found" class InvocationError(Error): """ an error while invoking a script.
