From f9134807d77edcd32cf62c34b8253791db0b833a Mon Sep 17 00:00:00 2001 From: Mostafa Abdelraouf Date: Thu, 16 Feb 2023 23:09:22 -0600 Subject: [PATCH] More Test coverage + fix some code coverage bugs (#321) Connection to the CI databases is viewed by Postgres as coming from localhost. The pg_hba.conf file generated by the docker image uses trust for these connections, that's why we had no test coverage on SASL and md5 branches. This PR fixes this issue. There was also an issue with under-reporting code coverage. This should be fixed now --- .circleci/config.yml | 28 +++++++++++----------------- .circleci/generate_coverage.sh | 6 +++--- .circleci/pgcat.toml | 4 ++-- .circleci/run_tests.sh | 5 ----- tests/docker/Dockerfile | 3 +++ tests/docker/docker-compose.yml | 11 ++++------- tests/docker/run.sh | 24 ++++++++++++++++++++---- tests/ruby/admin_spec.rb | 2 +- tests/ruby/load_balancing_spec.rb | 2 +- tests/ruby/spec_helper.rb | 2 +- 10 files changed, 46 insertions(+), 41 deletions(-) diff --git a/.circleci/config.yml b/.circleci/config.yml index ab0d773..f7aa899 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -9,39 +9,42 @@ jobs: # Specify the execution environment.
