Different testing environments play a vital role in this process, each serving a specific purpose to catch bugs and validate features.

From initial code creation in the development environment, to final validation in Production, these environments help streamline the development process and reduce risks.

We cover 6 different types of test environments including: development, integration, testing/QA, staging, production, and specialized environments. Each of these environment types contribute to a comprehensive testing strategy and understanding these environments is essential for efficient test management and delivering reliable software, so let's explore how and when to use them!

1. Development environment

The development environment is the initial workspace where software engineers write and test their code. It's a controlled setting that allows developers to experiment, make changes, and test new features without affecting other environments or the final product. This environment is crucial for the early stages of the software development process, providing a sandbox for developers to work on individual components and modules.

Key activities: initial code creation and unit tests

In the development environment, the primary activities include the creation of new code and the execution of unit tests. Initial code creation involves writing the source code for new features, functions, and fixes. Unit tests are small, automated tests that verify whether individual pieces of code (units) work as intended. These tests are typically written and run by developers to ensure that each part of the codebase functions correctly before it is integrated with other components.

Tools and practices used: version control, code repositories

To maintain organization and control within the development environment, developers use version control systems like Git. Version control allows multiple developers to work on the same project simultaneously without overwriting each other's changes. Code repositories, such as GitHub or Bitbucket, serve as centralized storage for the source code and track all changes made to the codebase. These tools facilitate collaboration, ensure code integrity, and provide a history of code changes that can be referenced or rolled back if necessary.
