Transcript

1. Best practices, troubles and ideas
2. omg a new logo Best practices, troubles and ideas
3. Outline - Step definition generalization - Test cases documentation - Different approach to BDD
4. Goals - Understand if a different approach might be useful - Advantages and disadvantages
5. Specifications Test cases Zenzu's task Some months ago
6. “Roberto, I need a test case that checks if there is a user in the db”. Specification
7. Given there exists a user Test case
8. User.count should be equal to 1 User.count should not be equal to 0 User.count should be greater than 0 Zenzu’s Task /^there exists a user$/
9. “Roberto, I need a test case that checks if there is only one user in the db”. Specification
10. Given there exists one user Given /^there exists one user$/ do
 expect(User.count).to be_eq 1 end Test case
11. “Roberto, I need another test case that checks if there are two users in the db”. Specification
12. Given there exists 1 user Given there exists 2 users : Given there exists N users /^there exists (\d) users?$/ Smart enough
13. Specifications (not well defined) Test cases (not well defined) Zenzu's task problem
14. Given there exists “peer@example.com”
15. Given there exists “peer@example.com”
16. Given there exists “godzilla@example.com” ?
17. Given there exists a peer with email “godzilla@example.com”
18. Given there exist “p1@ex.com” and “p2@ex.com”
19. Given the following users exist: | email | role | | p1@ex.com | peer | | c1@ex.com | collector |
20. Given there exist “p1@ex.com” and “p2@ex.com” who live in Trento
21. Given there exist “p1@ex.com” who lives in Trento and “p2@ex.com” who lives in Rome
22. Given there exist “p1@ex.com” who lives in Trento and “p2@ex.com” who lives in Rome Given there exist “p1@ex.com” and “p2@ex.com” who live in Trento Given the following users exist: | email | role | city | p1@ex.com | peer | Trento | p2@ex.com | peer | Rome Given there exist “p1@ex.com” who lives in Trento
23. #1: What is the right level of generalization we need?
24. Specifications Test cases Write test cases Now Write step definitions }Whole team
25. “Roberto, did you already write a test definition which …?”. Let me check.. “Did I already write a test definition which …?”.
26. #2: Not a question. We need documentation.
27. What I usually do
28. https://github.com/burtlo/yard-cucumber
29. Specifications Test cases Write test cases Now - Ideal Write step definitions }Whole team { (generalization)
 Zenzu’s task
30. Specifications Test cases Write test cases Now - Ideal Write step definitions }Whole team documentation
31. Given there exist :email who lives in :city and :email who lives in :city Given there exists :number :role btf metalanguage Given there exist an organization named :name with :number :role Given there exists 4 peers Given there exists 2 collectors
 
 Given there exists an organization named "Banco alimentare" with 4 peers Given there exists an organization named "Banco alimentare" with 4 collectors Given there exists an organization named "Banco alimentare" with 1 manager
