Fire events the same way the user does. user-event tries to simulate the real events that would happen in the browser as the user interacts with it. For example userEvent.click(checkbox) would change the state of the checkbox. user-event is a companion library for Testing Library that simulates user interactions by dispatching the events that would happen if the interaction took place in a browser. fireEvent dispatches DOM events, whereas user-event simulates full interactions, which may fire multiple events and do additional checks along the way. ...

HypoPG is a PostgreSQL extension that allows you to create hypothetical indexes without actually building them on disk. It helps developers and DBAs test the impact of potential indexes on query performance before committing resources. By simulating indexes, HypoPG assists in query optimization and index strategy planning without any performance or storage cost.

HammerDB is a leading benchmarking and load testing tool for relational databases like PostgreSQL, Oracle, SQL Server, and MySQL. It implements industry-standard workloads such as TPC-C and TPC-H to simulate real-world transactional and analytical database performance. HammerDB is widely used by DBAs and performance engineers to evaluate hardware, configurations, and scaling.

pg-mem is an in-memory PostgreSQL emulator for Node.js and TypeScript that allows you to simulate a Postgres database without a real server. It’s perfect for unit testing and development scenarios where spinning up a full database would be too heavy. pg-mem supports many Postgres features and is compatible with various ORMs like TypeORM and Sequelize.

sqlmock is a mock library implementing sql/driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow. In v1.2.0 sqlmock.Rows has changed to struct from interface, if you were using any type references to that interface, you will need to switch it to a pointer struct type. Also, sqlmock.Rows were used to implement driver.Rows interface, which was not required or useful for mocking and was removed. ...

DBIO is a tool to simulate Online Transaction Processing Database, which can be used to model production envirment for I/O test. A standard configuration file contained in the software simulates TPCC-Like I/O workload, which is modeled from DB2 Database running TPCC-Like workload. DBIO can also do data consistency check after the I/O workload test.

MakeDBO is a MySQL library for PHP. It includes a mysql database interface and a DBO class builder to automatically generate PHP classes from your database tables. Currently requires Smarty templating engine.

frCoder is a set of tools used to write, test, and simulate software written for the FIRST Robotics Competition (FRC). frCoder also includes basic libraries of common techniques used in the FRC.
