This document discusses continuous integration and automation testing. It describes continuous integration as a software development practice where changes are frequently integrated and validated through automated builds and tests. This allows teams to detect issues early and stabilize their products. The document provides details on continuous integration processes and practices, how to implement automation testing in a continuous integration environment, and the benefits such as faster feedback, reduced bugs, and improved quality. It also includes a case study on using the TeamCity tool to implement continuous integration and automation testing.

7. Continuous Integration & Automation Testing
CI Process
Developers check out code
and commit the changes to
the repository
The CI server monitor the
repository and checks out
changes when they occur
The CI server builds the
system and run unit tests
The CI server releases
deployable artifacts for QA
testing
Smarter. Faster. Closer.

8. Continuous Integration & Automation Testing
CI Process
The CI server assigns a build
label to the version of the code
that it just built
The CI server informs the team
of the successful build
If the build or tests fail, the CI
server alerts the team
The team fixes the issues at
the earliest opportunity

16. Continuous Integration & Automation Testing
TeamCity – real-time business case
Continuous Integration Build – for each commit / pre-tested commit –
just sanity build, no release / deploy – triggered automatically
Nightly Build – executed each night together with UnitTests, Automation
Tests, code quality step, code coverage step, eventually deploy on test
server if needed – triggered automatically
Sprint Build – manually executed on-demand for each end-sprint version
together with UnitTests, Automation Tests, code quality step, code
coverage step, deploy on test server – triggered manually
Release Build – manually executed on-demand for an official release
together with UnitTests, Automation Tests, code quality step, code
coverage step, deploy on test server – triggered manually
UAT Build - manually executed on-demand for an official release together
with UnitTests, Automation Tests, code quality step, code coverage
step, deploy on UAT server – triggered manually
