5 Signs You Need
CONTINUOUS INTEGRATION
How CI Revolutionized the Web Development World

A long, long time ago (well, not that long ago) when web applications were developed, they were coded, launched and then tested (in that order).
Testing was a tedious process since developers would click around the application to find bugs.
The man hours spent on this was long and expensive. As a result, new features being added to web applications took longer than it needed to be.
And then, Continuous Integration came along.
Continuous Integration or CI is cohesive approach to web application and software development. It is the process where developers deploy, integrate and test their code many times a day to a shared repository in smaller iterations as opposed to big chunks.
So, how do you know
if you need Continuous Integration?
#1There’s a team of developers working on separate components of your web application. And each developer is storing his/her code on their own machines.
One of the core principles of CI is to
maintain a single source repository.
Developers
commit their code several times a day
to the shared
repository where it is automatically tested.
This brings together the separate components the development team is working on in one place. By having the build tested automatically, developers can spend less time debugging and more time focused on building new features.
Software bugs cost the US economy
$59.6 billion annually.

Builds can automatically be built with a single line of code. This is a powerful feature of CI which allows companies to
automatically deploy applications.
Automated Deployment combined with Build Automation allows companies to save development time since developers
can deploy much faster (in a matter of
seconds as opposed to minutes and hours!).
#3Your development team is spending a big chunk of time debugging.
CI runs tests regularly instead of post-deployment or in the production environment. Whenever code is committed to the system, a build is created. Developers are notified to check the quality of their code if the test returns with an error.
CI will help you reduce your overhead costs of development by finding bugs during the development stage.
#4Releases are slower since
QA has to wait for the
actual deployment to happen.
CI is an excellent quality control systemsince testing is done during the development phases as well as post-deployment.
CI helps companies see trends and
manage code quality throughout
their development.
CI encourages your development team to generate API-like documentation for all the code committed by developers. It also provides real-time information on the code quality.
CI ensures higher code quality, quicker releases and an overall better end product.
And so with CI, the web development community rejoices!
