Continuous integration

1 Continuous integration


Continuous integration

1 Continuous integration (CI) is the practice, in software engineering, of

merging all developer working copies with a shared mainline several times

a day


Continuous integration - Theory

1 Continuous integration involves integrating early and often, so as to

avoid the pitfalls of "integration hell". The practice aims to reduce rework

and thus reduce cost and time.


Continuous integration - Theory

1 The rest of this article discusses best practice in how to achieve

continuous integration, and how to automate this practice. Build

automation is a best practice itself.


Continuous integration - Principles

1 Continuous integration – the practice of frequently integrating one's new or changed code with the existing

code repository – should occur frequently enough that no

intervening window remains between commit and build, and such that no errors can arise without developers noticing them and correcting them

immediatelyhttps://store.theartofservice.com/the-continuous-integration-toolkit.html

Continuous integration - Principles

1 To achieve these objectives, continuous integration relies on the following principles.


Continuous integration - Automate the build

1 Other more recent tools are frequently used in continuous integration environments


Continuous integration - Everyone commits to the baseline every day

1 Committing all changes at least once a day (once per feature built) is generally considered part of the

definition of Continuous Integration


Continuous integration - Every commit (to baseline) should be built

1 The system should build commits to the current working version in order to verify that they integrate correctly. A common practice is to use Automated Continuous Integration, although this may be done

manually. For many, continuous integration is synonymous with using Automated

Continuous Integration where a continuous integration server or daemon monitors the revision control system for changes, then

automatically runs the build process.


Continuous integration - History

1 Continuous Integration emerged in the Extreme Programming (XP) community,

and XP advocates Martin Fowler and Kent Beck first wrote about continuous

integration circa 1999. Fowler's paper is a popular source of information on the

subject. Beck's book Extreme Programming Explained, the original

reference for Extreme Programming, also describes the term.

Multi-stage continuous integration

1 'Multi-stage continuous integration' is a software

development technique intended to achieve highly integrated parallel

development activity while reducing the scope of integration problems. http://www.ddj.com/development-

Multi-stage continuous integration - Theory

1 Multi-stage continuous integration takes advantage of a basic unifying pattern of

software development: software moves in stages from a state of immaturity to a state

of maturity, and the work is broken down into logical units performed by interdependent

teams that integrate the different parts together over time. What changes from shop to shop is the number of stages, the number and size of teams, and the structure of the

team interdependencies.


Multi-stage continuous integration - Recommended Practices

1 Multi-stage continuous integration is an expansion upon continuous

integration, it presumes that you are already following those

recommended practices.


Multi-stage continuous integration - Recommended Practice #1

1 As they make changes, continuous integration is done against that team's

branch

Comparison of continuous integration software

1 Continuous integration describes a set of software engineering practices

that speed up the delivery of software by decreasing integration

times. Software that accomplish this practice is called 'continuous

integration software'.


Extreme programming practices - Continuous integration

1 The development team should always be working on the latest version of the

software. Since different team members may have versions saved locally with

various changes and improvements, they should try to upload their current version to

the code repository every few hours, or when a significant break presents itself. Continuous integration will avoid delays later on in the project cycle, caused by

integration problems.https://store.theartofservice.com/the-continuous-integration-toolkit.html
