Mocking an LDAP connection

[trekr5]

Hi,

I'm using Ruby to design an application that connects to an LDAP server.

I'm would like to develop tests to simulate my connection to the LDAP server as I don't want to connect to it every time I run my tests.

Can you suggest a way to mock/simulate this connection ?

Many thanks,

[Jerry Cheung]

The class that handles creating the socket is Net::LDAP::Connection. It's initializer allows you to pass in a `:socket` parameter that you can use for stubbing. For an example, check out https://github.com/ruby-ldap/ruby-net-ldap/blob/ec7b5dc0e1a323e2d47e9a4e8bc84235fd56160a/test/test_ldap_connection.rb#L46-L51. See pull request #116 for more background.

To follow up on this, you may want to consider creating a mock Net::LDAP object, or stubbing out method calls (like `ldap.search`) to return an Array of `Net::LDAP::Entry` objects, depending on your needs.

For instance, with mocha:

``` ruby

ldap = Net::LDAP.new(opts)

entry = Net::LDAP::Entry.new("uid=mtodd,ou=People,dc=rubyldap,dc=com")

ldap.expects(:search).returns([entry])

ldap.search #=> [#<Net::LDAP::Entry>]

```

or with a mock object:

``` ruby

entry = Net::LDAP::Entry.new("uid=mtodd,ou=People,dc=rubyldap,dc=com")

ldap = mock("Net::LDAP", search: [entry])

ldap.search #=> [#<Net::LDAP::Entry>]

```

Cheers,

Matt
