# This test does basic check around UNINSTALL and INSTALL PLUGIN commands.
#
# Test:
# 0. The test requires one server.
# 1. Bootstrap start GR.
#  - Verify that GR specific two P_S tables are not empty.
# 2. Uninstall plugin.
#  - Then uninstall it again twice; expect ER_SP_DOES_NOT_EXIST.
#  - Verify that GR specific two P_S tables are empty.
# 3. Install plugin.
#  - Then try installing it again twice; expect ER_UDF_EXISTS.
#  - Verify that GR specific two P_S tables are are not empty.
