Comparison of the best paid and free open source Continuous Integration (CI) Tools in 2022:
What is Continuous Integration?
CI is a method that enhances the quality of the code. It is a software engineering method that merges all developers working copies in a shared manner and environment.
It isolates the changes that are done immediately and report at the same time whenever they are added to a larger code base.

- Continuous Integration
- List Of The Top Continuous Integration Tools
The main objective of Continuous Integration is to provide rapid feedback when any defect is found in the code base and correct it as soon as possible. It automates the testing process on a server and provides automatic reporting to the user.
The Plan, Code, Build, and Test are the workflows or common steps of the CI process. This sequence of steps is called a pipeline. Each tool uses these steps or some extra steps for processing.
