Ubuntu15.10's first daily build image is now available for download. Werewolf's daily build includes ISO images, regular (using Unity) and Community styles (using tumate and Xubuntu ). The daily build versions will be released in the next six months. These images will be released as Alpha, beta, or RC versions. Ubuntu15.10 is currently released on July 10, Octobe

Connection and difference between daily build and continuous integration 1) continuous integration emphasizes a fast feedback.For example, when I check in the code, I immediately integrate it and give me a feedback. I want to know if my code has destroyed the build.Continuous integration is combined with unit testing. That is to say, unit testing is usually required for continuous integration. However, continuous integration cannot include more things

The connection and difference between building and Continuous Integration on a daily basis 1) Continuous Integration (Continuous Integration) emphasizes a fast feedback. For example, when I check in the code, I immediately integrate it and give me a feedback. I want to know if my code has destroyed the build. Continuous integration is combined with unit testing. That is to say, unit testing is usually required for continuous integration. However, cont

It is inevitable that the test link will be released to the production environment. Generally, this is to avoid risks through some testing check tools to check the link, below we will briefly describe the general implementation ideas. Many Internet companies may encounter tests, prerelease, and online environments, to isolate the test from the formal online environment. In this case, the test link is released to the production environment, generally, some testing tools are used to check links to
