Aubergine (BDD for .net) v0.07 : support for Given-I-did-clause
Hi there,
V0.07 is here :
Changes:
* Support for "Given I did" clause (more info in this essay )
* Complete refactoring of the Account example after extending the account story (my usual Model/Service layout, although the interfaces are missing here)
Here is the current example of the account story (copied from the essay):
Appendix A : a working example story :
Context Be.Corebvba.Aubergine.Examples.Accounts.Contexts.AccountContext
ContextDLL Be.Corebvba.Aubergine.Examples.DLL
Story Transfer money between accounts
As a user
I want to transfer money between accounts
So that I can have real use for my money
Given the balance of AccountA is 3m
Given the balance of AccountB is 2m
Given the owner of AccountA is the current user
Scenario Authenticate the current user as a 'valid or invalid' user
Given the name of the current user is 'username'
And the password of the current user is 'password'
When I request authentication for the current user
Then the process should 'fail or succeed'
Example
+--------------------+------------+------------+------------------+
| 'valid or invalid' | 'username' | 'password' | 'fail or succeed'|
+--------------------+------------+------------+------------------+
| valid | Neo | Red pill | succeed |
| invalid | Neo | Blue pill | fail |
+--------------------+------------+------------+------------------+
Scenario Authenticate the current user for 'an account'
Given I did authenticate the current user as a valid user
When I request authentication for 'an account' with the current user
Then the process should 'fail or succeed'
Example accounts :
+--------------+-------------------+
| 'an account' | 'fail or succeed' |
+--------------+-------------------+
| AccountA | succeed |
| AccountB | fail |
+--------------+-------------------+
Scenario Transfer AAm between 2 accounts
Given I did authenticate the current user for AccountA
When I transfer AAm from AccountA to AccountB with the current user
Then the balance of AccountA should be BBm
Then the balance of AccountB should be CCm
Then the process should 'fail or succeed'
Example for the transfer
+----+----+----+-------------------+
| AA | BB | CC | 'fail or succeed' |
+----+----+----+-------------------+
| 1 | 2 | 3 | succeed |
| 2 | 1 | 4 | succeed |
| 3 | 0 | 5 | succeed |
| 4 | 3 | 2 | fail |
+----+----+----+-------------------+
