问题
I was developing sample project of Rails tutorial (M. Hartl) but at the end of chapter 9 I got failure for integration testing.
Assertion of test is like below:
assert_select 'a[href=?]', user_path(user), text: user.name
Body of error is:
FAIL["test_index_as_admin_including_pagination_and_delete_links", UsersIndexTest, 2016-01-25 23:03:39 +0330]
test_index_as_admin_including_pagination_and_delete_links#UsersIndexTest (1453750419.70s)
Expected at least 1 element matching "a[href="/users/157312430"]", found 0..
Expected 0 to be >= 1.
So used byebug for debugging of test but not found any problem with it. Response of server to test module is as here (Result of "JSON.parse(response.body)"):

Response of watching "p user" is:
#<User id: 14035331, name: "User 19", email: "user-19@example.com", created_at: "2016-01-26 04:13:50", updated_at: "2016-01-26 04:13:50", password_digest: "$2a$04$dTwCZcN7xWivGrZvlJrpzuBNZDaOKd4paCesVp8tK0k...", remember_digest: nil, admin: false>
Update:
Integration test is:
test "index as admin including pagination and delete links" do
log_in_as(@admin)
get users_path
assert_template 'users/index'
assert_select 'div.pagination'
first_page_of_users = User.paginate(page: 1)
first_page_of_users.each do |user|
byebug
assert_select 'a[href=?]', user_path(user), text: user.name
unless user == @admin
assert_select 'a[href=?]', user_path(user), text: 'delete',
method: :delete
end
assert_difference 'User.count', -1 do
delete user_path(@non_admin)
end
end
end
回答1:
As Tetiana Chupryna said, I revised my test's source and found out problem was iterating users to following part of code (wrong placement of end).
Updated version of test which works fine:
test "index as admin including pagination and delete links" do
log_in_as(@admin)
get users_path
assert_template 'users/index'
assert_select 'div.pagination'
first_page_of_users = User.paginate(page: 1)
first_page_of_users.each do |user|
assert_select 'a[href=?]', user_path(user), text: user.name
unless user == @admin
assert_select 'a[href=?]', user_path(user), text: 'delete',
method: :delete
end
end
assert_difference 'User.count', -1 do
delete user_path(@non_admin)
end
end
