Continuous Integration: • The practice

• Merging working copies several times a day + building

• To prevent integration problems

Continuous Testing: • The practice in combination with Continuous Integration

• Run automated tests on different levels for each build

• To provide a rapid feedback about the current build

7

Continuous Delivery: • To ensure that application can be rapidly and safely

deployed to production by push of a one button

• Delivering every change to a production-like environment

• Run automated tests

Continuous Deployment: • The next step of Continuous Delivery

• Application passes the automated tests is deployed to

production by push of a one button
