Docker is not a full-fledged Virtual Machine, but rather a container. Docker enables you to run instances of services/servers in a specific virtual environment. A good example of this would be running a Docker container with Ruby on Rails on Ubuntu Linux.

- It may be used to debug tests, alter and record and is also available as a Firefox extension.
- Continuous Testing constitutes the running of automated tests as part of the software delivery pipeline to provide instant feedback on the business risks present in the most recent release.
Explain the difference between a centralized and distributed version control system . Any modification to the code may be tested immediately with Continuous Testing. This prevents concerns like quality https://remotemode.net/ issues and releases delays that might occur whenever big-bang testing is delayed until the end of the cycle.
