Which term defines software development where code updates are tested and committed to a development environment?

• A. Sandbox
• B. Continuous Integration
• C. Code Signing
• D. Fuzzer

Answer: (D)

Continuous Integration is the practice where code updates are frequently merged into a shared development repository, then automatically built and tested to verify that the changes work together. This approach ensures updates are validated in a development-like environment before moving toward release, catching integration issues early. In a CI workflow, every commit triggers a build, runs unit and integration tests, and highlights any problems. The other terms describe different ideas: a sandbox is simply an isolated testing space, code signing verifies who authored and modified code, and a fuzzer automatically feeds strange inputs to a program to uncover vulnerabilities.
