Which environment is primarily used for testing builds before they are moved to production?

The environment primarily used for testing builds before they are moved to production is referred to as the "TST" environment. In the software development lifecycle, this testing environment is crucial for ensuring that the application functions correctly and meets the required specifications after development.

Typically, the TST (Test) environment replicates the production environment closely but allows for debugging and validation without affecting live users. This setup enables developers and testers to execute a variety of tests, including functional, regression, and performance tests, ensuring that any issues are identified and resolved before deployment.

Additionally, utilizing a dedicated testing environment helps maintain the integrity of the production environment by preventing unintended disruptions caused by incomplete or faulty code. This structured approach to testing is a standard practice in software development and deployment, underscoring the significance of the TST environment in promoting a smooth transition to production.
