Environments in software development

Environments in software development represent the different stages an application passes through before reaching end users. Each one exists to test, validate or prepare the application from a particular angle, ensuring its quality and stability.

The most common environments

• Developer machine — the developer’s own computer, for coding and basic testing.
• Unit — to test components in a server environment, off the developer’s machine.
• Functional — where analysts test independently and validate features without disrupting developers.
• Integration — to test several applications together and validate their interoperability.
• Acceptance — validation by the product owners, confirming everything meets the needs.
• Pre-production — which should be identical to production, for final checks.
• Production — where the application is used by end users. No longer a testing space.
• Hotfix — an exceptional environment to quickly apply a critical fix without going through all the others.
• Training — so trainers and future users can get familiar with the application.

One shared goal

Every organization may name or use these environments differently. But the goal stays the same: to secure the application’s journey so the final version is as reliable as possible.
