DuckDB Java issues

A set of tests aiming to reproduce encountered problems while using DuckDB JDBC driver.

Requirements

• A JRE 17 or higher

• Optional If you do not want to use Gradle wrapper:

  • JDK 21 or higher

  • Gradle 8.14 or higher

Run tests

Run ./gradlew build.

Test report is available at build/reports/tests/test/index.html.

Run a single test

Run ./gradlew test --tests=$TEST_CLASS_NAME

Example: run test validating test database migration (source here):

./gradlew test --tests=MigrationValidationTest

This will replace the test report in build directory.

Sources

Test cases are located in src/test/java/com/geomatys/duckdb/test/.

Tests inherit from AbstractDuckDbTest class. It creates an ephemeral database for each test. The database is filled with test data. SQL definition is in src/test/resources/db/migration/.
