create test CI

[piobig2871]

In order to understand the importance of CI, it’s helpful to first discuss some pain points that often arise due to the absence of CI. Without CI, developers must manually coordinate and communicate when they are contributing code to the end product. This coordination extends beyond the development teams to operations and the rest of the organization. Product teams must coordinate when to sequentially launch features and fixes and which team members will be responsible.

The communication overhead of a non-CI environment can become a complex and entangled synchronization chore, which adds unnecessary bureaucratic cost to projects. This causes slower code releases with higher rates of failure, as it requires developers to be sensitive and thoughtful towards the integrations. These risks grow exponentially as the engineering team and codebase sizes increase.

Without a robust CI pipeline, a disconnect between the engineering team and the rest of the organization can form. Communication between product and engineering can be cumbersome. Engineering becomes a black box which the rest of the team inputs requirements and features and maybe gets expected results back. It will make it harder for engineering to estimate time of delivery on requests because the time to integrate new changes becomes an unknown risk.
