Microservices is an architectural style in which one application is built as a set of small services, each running in its own process, owning its own data and talking to the others over lightweight network calls, so that each can be built, deployed and scaled on its own.

Continuous integration is the practice of every developer merging their work into a shared mainline at least once a day, with an automated build and test run on each merge, so that integration problems surface within minutes of being created rather than weeks later at release time.

Unit testing is the practice of writing small automated checks that call one piece of code in isolation, a function, a class or a module, with known inputs and assert on its outputs, so that a change which breaks that behaviour fails a test within seconds of being made.
