To easily limit the execution of RSpec tests while you are developing use the power of the .rspec opts file and RSpec tags.

Tags can be added to any RSpec method describe, context, it, etc.

The are simply arguments passed as a Hash to the method.

describe 'foo', focus: true do
 context 'bar', slow: true do

Postgres EXPLAIN Lunch & Learn @ BenchPrep

EXPLAIN Explained video on YouTube

What EXPLAIN doesn't do

• Tell you why a particular index isn't used
• Explain how to rewrite your queries
• Show what other factors make the DB slow
• Tell you how much time the request took outside the DB
