Further Reading I vividly remember one of my first sightings of a large software project. I was taking a summer internship at a large English electronics company. My manager, part of the QA group, gave me a tour of a site and we entered a huge depressing warehouse stacked full with cubes.
I was told that this project had been in development for a couple of years and was currently integrating, and had been integrating for several months. My guide told me that nobody really knew how long it would take to finish integrating.
From this I learned a common story of software projects: Most projects done by my colleagues at ThoughtWorks, and by many others around the world, treat integration as a non-event. Any integration errors are found rapidly and can be fixed rapidly.
The essence of it lies in the simple practice of everyone on the team integrating frequently, usually daily, against a controlled source code repository. The original article on Continuous Integration describes our experiences as Matt helped put together continuous integration on a ThoughtWorks project in Thus the third common reaction is "yes we do that - how could you live without it?
When I started at ThoughtWorks, as a consultant, I encouraged the project I was working with to use the technique. Matthew Foemmel turned my vague exhortations into solid action and we saw the project go from rare and complex integrations to the non-event I described.
Matthew and I wrote up our experience in the original version of this paper, which has been one of the most popular papers on my site. The best known such server is CruiseControl, an open source tool originally built by several people at ThoughtWorks and now maintained by a wide community.
Since then several other CI servers have appeared, both open source and commercial - including Cruise from ThoughtWorks Studios. Building a Feature with Continuous Integration The easiest way for me to explain what CI is and how it works is to show a quick example of how it works with the development of a small feature.
I begin by taking a copy of the current integrated source onto my local development machine. I do this by using a source code management system by checking out a working copy from the mainline.
So let me quickly explain that for the latter. Now I take my working copy and do whatever I need to do to complete my task. This will consist of both altering the production code, and also adding or changing automated tests.
Continuous Integration assumes a high degree of tests which are automated into the software: Often these use a version of the popular XUnit testing frameworks. This takes the source code in my working copy, compiles and links it into an executable, and runs the automated tests.
Only if it all builds and tests without errors is the overall build considered to be good. With a good build, I can then think about committing my changes into the repository.
The twist, of course, is that other people may, and usually have, made changes to the mainline before I get chance to commit. So first I update my working copy with their changes and rebuild. If their changes clash with my changes, it will manifest as a failure either in the compilation or in the tests.
Once I have made my own build of a properly synchronized working copy I can then finally commit my changes into the mainline, which then updates the repository. At this point we build again, but this time on an integration machine based on the mainline code.
Only when this build succeeds can we say that my changes are done. Only when my committed changes build successfully on the integration is my job done.
This integration build can be executed manually by me, or done automatically by Cruise.
If a clash occurs between two developers, it is usually caught when the second developer to commit builds their updated working copy.
If not the integration build should fail. Either way the error is detected rapidly. At this point the most important task is to fix it, and get the build working properly again. In a Continuous Integration environment you should never have a failed integration build stay failed for long.
A good team should have many correct builds a day.Oct 02, · Expository Essay Topic Ideas, Writing Tips, and Sample Essays. Updated on May 15, Virginia Kearney. Want a fast and easy essay? Follow these three easy steps: Choose a great topic: There are a lot of great essay topics in this Hub.
