Email: johan@open-future.be

3. Why this talk ?
●
We want to do it the 'good' way -> TDD
●
rspec-puppet.com – rspec for modules
●
...
●
No docs found, any pointers ?
●
Looking at the puppet code to learn

4. What is Test Driven Development

5. Benefits of TDD
●
Test case from the beginning
●
Tests are maintained during life cycle
●
Small moves – coding just to pass test
●
Encourage simple design
●
First step in test automation

6. TDD does not
●
Replace integration testing
●
Replace compliance testing
●
.......

7. TDD for a sysadmin
●
We have to learn developing
●
Huge mindshift
●
Culture schift
●
Rspec for modules is ok
–
●
Writing modules is already adopted by sysadmin
see Rspec-puppet.com => tutorial
Rspec for type/providers
–
Still looking for docs
–
Use the (puppet) source

9. Filling the gap ...

●
Initial attempt write Type using TDD

et_rspec_demo
In need of help (i'm kind of stuck)
●
Looking for input how to do it right
●
Hopefully it results in a good tutorial
