The document outlines the implementation of an Agile software factory with a focus on continuous integration and delivery (CI/CD) practices for Project X. It details feature development from customer perspectives, the integration of various tools like Jenkins and Jira, and the challenges of utilizing cloud environments for testing and deployment. Additionally, it discusses strategies for QA automation and the importance of collaboration between development and operations teams.

Continuous Delivery infrastructure
requires diverse toolset.
There is no single tool that
implements CICD infrastructure
end-to-end.

─ Shortage or rigidness of corporate datacenter resources slows down development process and hampers innovation
─ Use public cloud to host developer’s sandboxes and QA environments

22. QA Automation Vision
22
Manual test suite
(typically end-to-end user acceptance
tests)
Automated
Functional Modular
(test each service or application
individually with stubbed external
dependencies and test data)
Auto Integration
(testing integration of each service or
application with real external
dependencies and production data)
User acceptance
(testing system as a whole using UI with
real external dependencies and production
data)
Manual execution
time –
weeks
Full automatic
execution
time –
hours
1. Save on manual QA effort and reduce time to run regression automatically
2. Create fine-grained modular tests for each service or application to increase test coverage
3. Implement more tests to increase quality – running tests automatically is cheap
Staged execution: start
with faster and more
granular tests to find
defects quickly

23. QA Automation Process Vision
23
1. Integrate QA automation team with Development team to increase productivity and efficiency
2. Use Acceptance Test Driven Development approach, implement automatic tests together with code development

First deployment on staging / production doesn’t go well.
However, this is the point when
development and operations
start collaborating first.
