# Sets the environment used by the cx_Oracle test suite. Production
# applications should consider using External Authentication to
# avoid hard coded credentials.
#
# You can set values in environment variables to bypass having the test suite
# request the information it requires.
#
# CX_ORACLE_TEST_MAIN_USER: user used for most test cases
# CX_ORACLE_TEST_MAIN_PASSWORD: password of user used for most test cases
# CX_ORACLE_TEST_PROXY_USER: user for testing proxying
# CX_ORACLE_TEST_PROXY_PASSWORD: password of user for testing proxying
# CX_ORACLE_TEST_CONNECT_STRING: connect string for test suite
# CX_ORACLE_TEST_ADMIN_USER: administrative user for test suite
# CX_ORACLE_TEST_ADMIN_PASSWORD: administrative password for test suite
#
# CX_ORACLE_TEST_CONNECT_STRING can be set to an Easy Connect string, or a
# Net Service Name from a tnsnames.ora file or external naming service,
# or it can be the name of a local Oracle database instance.
#
# If cx_Oracle is using Instant Client, then an Easy Connect string is
# generally appropriate. The syntax is:
#
# [//]host_name[:port][/service_name][:server_type][/instance_name]
#
# Commonly just the host_name and service_name are needed
# e.g. "localhost/orclpdb1" or "localhost/XEPDB1"
#
# If using a tnsnames.ora file, the file can be in a default
# location such as $ORACLE_HOME/network/admin/tnsnames.ora or
# /etc/tnsnames.ora. Alternatively set the TNS_ADMIN environment
# variable and put the file in $TNS_ADMIN/tnsnames.ora.
#
# The administrative user for cloud databases is ADMIN and the administrative
# user for on premises databases is SYSTEM.
