Continuous Integration
Continuous Integration (CI) is a development practice in which developers frequently integrate code changes into a shared repository, where automated builds and tests are executed.
“An automated software development procedure that merges, integrates and tests all changes as soon as they are committed.”

Continuous integration helps teams detect integration problems early by automatically building and validating software whenever changes are committed.
Frequent integration: Small code changes reduce merge conflicts.
Automation: Builds and tests execute automatically after each integration.
Fast feedback: Developers receive rapid notification of build or test failures.
Real World Example
An insurance claims platform is connecting a claim intake service, a policy validation service, and a payment approval service.
Each part can look correct in isolation while the handoff between parts still fails. Continuous integration helps testers focus on the boundary where data, timing, and responsibility meet.
The tester checks payloads, error handling, retries, missing fields, and the order of service calls instead of only confirming that each screen appears.
The claims flow becomes more dependable because Continuous integration exposes defects that only appear when real components collaborate.
