- 12. Database Rider is a nice replacement This project aims for bringing DBUnit closer to your JUnit tests so database testing will feel like a breeze! So you can ride the database in your JUnit tests! https://github.com/database-rider/database-rider
- 13. Why is it so good? Open source with friendly contributors team Minimal set of dependencies, pure JDBC implementation Simple, powerful and very flexible Still wrapper around DBUnit with all it’s features Integrations with JUnit 4/5, CDI and Cucumber Advanced features like leak detection, constraints management and datasets generation Good documentation with many examples
- 17. Code examples on Github https://github.com/xpinjection/test-driven-spring-boot
- 18. Basics features summary YAML, JSON, XML, CSV and even Excel format support Full set of data management strategies Ability to carefully clear database before/after test Extended DB configuration with SQL support before/after test Multiple datasets could be applied
- 19. Advanced features summary DTD/XSD could be used for datasets validation File and live templates in IDE simplify your life Groovy and JavaScript for smart data generation Export datasets with @ExportDataSet or DataSetExporter to speed up datasets creation Powerful export with SQL queries and tables filtering Programmatic data sets creation with DataSetProvider and DataSetBuilder Meta-annotations for configuration reuse
- 22. Basics features summary Several datasets could be specified in @ExpectedDataSet for assertion Some columns may be ignored for datasets reuse Regular expressions for complex assertions Ordering by set of columns
- 23. Advanced features summary Configurable set of Replacers to implement custom logic (nulls, date/time shift, etc.) Programmatic provider to generate dataset from code Contains and equals data comparison
- 26. Basics features summary Global configuration in dbunit.yml Local configuration at class/test level with @DBUnit Executor scope for multiple logical databases support EntityManagerProvider rule for JPA entity manager provider Merging of class and test level data sets Externalized connection management Configurable caching
- 29. Advanced features summary Transactions management Flexible table filtering and ordering for data cleanup Disabling constraints to simplify data management Connection leak detection CDI integration Cucumber integration
- 30. WTF?!? You told us this is very simple library!
- 31. Summary and take aways Database Rider simplifies your testing experience You could use it for any kind of tests (unit, integration, API, system) Generate datasets where possible Use full power of IDE to speed up datasets creation Experiment with advanced features like leak detection Contribute if your case is not covered
