3. TYPICAL
• As a tester, do you need to wait for an
acceptable release from developers?
• Loose time doing all repetitive manual stuff?
• Maintain different environments and software versions manually,
over-and-over-and-over…
• Didn't we fix this issue three months ago?
• Is this really release 1.6.5?
All sounds familiar?

8. WHAT ARE THE MAIN STEPS OF CONTINUOUS DELIVERY?
• Build – compile, unit test, version, package
• Quality – metrics, documentation
• Test – acceptance-, regression- and performance tests
• Provision environments – deployment to test- and staging
environment
• Production – green/blue deployment to production

Every change results in a trigger of the deployment process
Software is build once and only once
The same deployment process for every environment
Deployment in production-like environments

But try to automate as much as possible
