Specifications Test cases Zenzu's task Some months ago

Slide 6

Slide 6 text

“Roberto, I need a test case that checks if there is a user in the db”. Specification

Slide 7

Slide 7 text

Given there exists a user Test case

Slide 8

Slide 8 text

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$/

Slide 9

Slide 9 text

“Roberto, I need a test case that checks if there is only one user in the db”. Specification

Slide 10

Slide 10 text

Given there exists one user Given /^there exists one user$/ do
 expect(User.count).to be_eq 1 end Test case

Slide 11

Slide 11 text

“Roberto, I need another test case that checks if there are two users in the db”. Specification

Slide 12

Slide 12 text

Given there exists 1 user Given there exists 2 users : Given there exists N users /^there exists (\d) users?$/ Smart enough

#1: What is the right level of generalization we need?

Slide 24

Slide 24 text

Specifications Test cases Write test cases Now Write step definitions }Whole team

Slide 25

Slide 25 text

“Roberto, did you already write a test definition which …?”. Let me check.. “Did I already write a test definition which …?”.

Slide 26

Slide 26 text

#2: Not a question. We need documentation.
