From 1ff429da2a94bc79300ebce3f8aae7efb10e9a75 Mon Sep 17 00:00:00 2001 From: Masood Malekghassemi Date: Thu, 2 Jun 2016 16:39:20 -0700 Subject: Organize Python tests to use grpcio-tools directly Moves all tests into a separate package. This does not change existing supported means of running tests (e.g. through run_tests.py). --- .gitignore | 2 + setup.py | 44 +- src/python/grpcio/commands.py | 146 ----
