Testing Legacy Apps

Testing Legacy Apps
Dawn Cannan, agile tester

You are a tester on a team that is “going agile” or has “gone agile”
Most testing has been people manually clicking and typing on the “QA Server”
Bug reports have been filed and many ignored for a while, leading to a huge bug database
The test team now has to figure out how to “go agile”, too
Or, maybe you’re new to a team that has never had a tester or test team before
Does this sound familiar?

So many “types” of testing, and how much of each do we need?
What’s the “big picture”?

Test Automation Pyramid
* Pyramid via Mike Cohn

Agile Testing Quadrants
* Quadrants via Lisa Crispin and Janet Gregory

Mike Cohn describes it well in a 3-step process
Where do we start?

Stop the bleeding
Identify frequent and
time-consuming tasks
Begin to automate them
Begin to run them
regularly
“Hey developer, can you
help me with this?”

Pair Testing

Start pair-developing (pair tester with dev)
Start writing test
automation with new
features
Regular builds or
continuous integration
“Done” means coded
and tested (and documented, if needed)
Stay Current

Pair Programming

Start to fill in automation of regression tests
Some UI tests
Many FitNesse/
integration tests
LOTS OF unit
tests
Begin to
refactor both
code and tests
Catch Up
