Instance Method Details

#have_executed(entry_point) ⇒ Object

A matcher for asserting that database statements have (or have not) been executed. Usage:

ActiveRecord::Base.connection.should have_executed(:insert)

The types of statement that can be matched mostly mirror the public operations available in ActiveRecord::ConnectionAdapters::DatabaseStatements:

  • :select_one

  • :select_all

  • :select_value

  • :insert

  • :update

  • :delete

  • :execute

There is also a special :anything symbol that will match any operation.
