#assert_database_not_present(db_settings_hash) ⇒ Object

Asserts a database doesn’t exist. To do so this method tries to establish a connection with the specified database. Connection information must be provided with a hash. This method assert if connection fails, but that could also mean that provided connection hash is wrong. The connection options are the same as in assert_database_present:

:database

=> database name

:host

=> database host

:username

=> database user

:password

=> database password

:adapter

=> database type (default is "mysql")

These options correspond to those in Activerecord::Base.establish_conection

#assert_not_parsed(message_symbol) ⇒ Object

Asserts that a message in a xml fixture file is converted into an Adaptation::Message that if serialized again to xml is not equivalent to the xml data in the initial fixture file. An Adaptation::Message object cretaed from a xml fixture, will only have the xml tags specified in its class definition (using has_one, has_many, has_text…) so this assertion can be useful to check that undesired xml tags are filtered.
