The Magic Tricks of Testing

Sandi Metz

• Many people say "I hate my tests"
• They kill your productivity when they're slow
• A little change can break your tests (even if they shouldn't)
• They're expensive
• They are misery incarnate
• Just delete some tests
• You may have too many tests testing the wrong tests

record = Post.new(:title => 'Yay', :body => 'This is some insert SQL')

# easiest way to achieve this is by calling protected #arel_attributes_values (tested in
# rails 3.2.13). the alternative is to build the entire insert statement using arel >_>
record.class.arel_table.create_insert \
                       .tap { |im| im.insert(record.send(:arel_attributes_values, false)) } \
                       .to_sql
