Then share ids should match
Scenario: unique target names for incomming shares
Given user "user0" exists
And user "user1" exists
And user "user2" exists
And user "user0" created a folder "/foo"
And user "user1" created a folder "/foo"
When file "/foo" of user "user0" is shared with user "user2"
And file "/foo" of user "user1" is shared with user "user2"
Then user "user2" should see following elements
| /foo/ |
| /foo%20(2)/ |
