JDBC Tester

JDBC tester is a domain-specific tool for developers and QA engineers to validate JDBC driver jars, ensuring that a given jar can load a driver, connect to a database URL, and execute a lightweight query without full application deployment. It helps teams confirm compatibility between a database, driver jar, and Java runtime in local builds and CI pipelines.
Conceptually the tool accepts: path to the jar, JDBC URL, fully-qualified driver class, user credentials, and an optional test query or metadata scan. It loads the driver class, establishes a connection, retrieves basic metadata (product name, version, and driver version), and runs the test query to verify behavior. Results include connection status, latency, and any exceptions, suitable for dashboards or logs.
Unique value lies in testing a real jar in isolation, enabling quick iteration when swapping drivers or databases, and producing structured outputs for automation. It does not spin up servers; it validates existing targets and reports actionable details for remediation and documentation.
