The document discusses Test Driven Development (TDD) and its importance for sysadmins, particularly in relation to Puppet and RSpec. It highlights the cultural shift required to adopt TDD practices, the benefits of maintaining test cases throughout the development lifecycle, and the necessity for additional documentation and tutorials. The authors seek community input and collaboration to improve their implementation of TDD with Puppet.

Puppet

●
●

●
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
https://github.com/Open-Future-Belgium/pupp
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
