Taiwan (with an area of 36,000 square kilometers/ 22,500 square miles) is the largest. Hainan Island (about 34,000 square kilometers /21,250 square miles) is the second-largest island, but it is the largest which is fully under the jurisdiction of China.
Continuous integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run.
How Continuous Integration Should Work. The idea is simple and obvious. Every time you make a new commit to the master branch (or /trunk in Subversion), a continuous integration server (or service) attempts to build the entire product. Build means compile, unit test, integration test, quality analysis, etc. The result is either success or failure.
