Testing Clients Locally

We can test the clients locally by executing the below commands that are required to install dependencies, run Docker containers and perform a series of query execution in the database engine to ensure it’s working as expected…

PostgreSQL

docker run \
  --env=POSTGRES_PASSWORD=postgres \
  --env=PGDATA=/var/lib/postgresql/data \
  --volume=/var/lib/postgresql/data \
  -p 5432:5432 -d postgres:12.18-bullseye

python manager.py run-database-test \
  -client PostgresClient \
  -params '{"conninfo":"postgresql://postgres:postgres@localhost:5432/postgres"}'

MySQL

docker run \
  --env=MYSQL_ROOT_PASSWORD=mysql_password \
  --volume=/var/lib/mysql \
  -p 3306:3306 \
  --restart=no \
  --runtime=runc \
  -d mysql:latest

python manager.py run-database-test \
  -client MySQLClient \
  -params '{"host": "localhost", "database": "sys", "user": "root", "password": "mysql_password"}'

Oracle

docker pull container-registry.oracle.com/database/express:latest
docker container create -it --name OracleSQL -p 1521:1521 -e ORACLE_PWD=oracle_password container-registry.oracle.com/database/express:latest
docker start OracleSQL

python manager.py run-database-test \
  -client OracleClient \
  -params '{"user": "SYSTEM", "password": "oracle_password", "dsn": "localhost:1521/xe"}'

MsSQL

docker pull mcr.microsoft.com/mssql/server:2022-latest

docker run\
  -e "ACCEPT_EULA=Y" \
  -e "MSSQL_SA_PASSWORD=sOm3str0ngP@33w0rd" \
  -p 1433:1433 --name MsSQL --hostname MsSQL \
  -d mcr.microsoft.com/mssql/server:2022-latest

docker start MsSQL
sudo /bin/bash ./scripts/install_mssql_driver.sh

python manager.py run-database-test \
  -client MsSqlClient \
  -params '{"dsn": "DRIVER={ODBC Driver 18 for SQL Server};SERVER=localhost;DATABASE=master;UID=SA;PWD=sOm3str0ngP@33w0rd;Encrypt=no"}'
