Description

Currently, the example tests are implemented as plain Go tests using assert/require to validate the cases. This approach is difficult to scale and maintain.
Using a BDD framework would make understanding the test scenarios and adding new ones as well as maintaining the code much easier.

Acceptance Criteria

• A BDD framework suitable for running the example tests is identified
• As a PoC, the nodejs_postgresl example test is refactored to use that BDD framework.
