Canary testing reduces the risk and develops new software by releasing it to a small percentage of users. With the help of Canary testing, you can deliver your development to a specific group of users at a given period. This is also referred to as incremental or staged. This is the best practice in software development.

With the help of blue-green deployments, Canary testing is carried out to split traffic at the server level and then slowly roll over traffic from one application to a new version of the application using a router at a server level.

It will allow a new code to be released for a smaller number of users so that you can verify any issues with the regulations before you release it to a larger audience. When you release it to a smaller audience, it will be easy for the team to validate the performance. It will be easy for the team to validate the implementation before giving it to a large audience.

Canary testing is also done with the help of feature flags that will help the team to separate codes. These are released with feature enablement and then turn features on and off remotely for particular groups. When you use feature flags, the percentage of users is only 1%.

This process is very beneficial since it is not released to a larger audience. It will be easy to disable by turning the feature flag off. It will help avoid loss in revenue and massive downtimes. This will also help the team quickly learn the performance of the new features and limit the loss.

This testing is also used in software engineering to work on different practices of continuous delivery and constant integration that will help in the faster development of cycles and feature management.
