The New Era

Yes, CI improves quality

I will start with a 2 liner snippet around Continuous Integration.

CI is a blessing for testers as it offers variety of benefits. As an organization, if you're not using Continuous Integration, my word of advice

is “Just give it a try”.

In this blog, I would like to explain why Continuous Integration and Jenkins are the ideal fit for any agile driven process oriented organization.

CI is the practice of merging all developer workspaces several times a day with a shared mainline

CI servers constantly monitor source code repositories

Avoids or detects compatibility issues early

Keeps workspace continually integrated with other developers

Reduces less bugs – run a strong test suite against the code

Integrates code with mainline, compiles and runs automated tests

Deploys working piece of code at any point of time in the system

Helps the developer to get early feedback on their code

Reduces fixed cost: If a defect is introduced into the system, it can be identified and corrected as early as possible

Continuous Integration using Jenkins – It’s a 100% win-win situation

Large teams working on same code base

Multiple stages of code deployments

Conflicts between geographically scattered teams

One of the hottest topics today in Application Development and Application Testing in general should be around Continuous Integration. Why

there is so much buzz around this term? Well, there are obvious reasons such as it can a) improve the quality of the application b) isolate and resolve

defects faster c) drastically improve tools, processes, and test suite. Predominantly, there are few challenges that the testing folks can address

quickly with the help of Continuous integration.

- Average time spent on the portal increased from 19 sec to 130 sec, because of advanced technologies used in UX engineering

- 30% of development time was saved using our Solution Accelerators

- The Portal can support almost one million profiles and it is further scalable

- The portal was designed in an eventual consistency model, to accommodate enormous number of acs from end users

If it is Continuous integration, then the marriage with Jenkins is made in heaven. Jenkins is a java based Continuous Integration tool and

it has its own capabilities, features and strengths

To conclude with, I would like to list down some of the notable benefits you can get as a tester when you are using Jenkins as a

Continuous Integration tool.

Jenkins comes as a war file WAR file and can be started by simply executing "java-jar jenkins.war". No database, no special installation, no special registration
