RSpec and Cucumber: Shorthand syntax to run multiple line numbers in the same file

This works in modern RSpecs (RSpec >= 2.x) and Cucumbers:

rspec spec/models/node_spec.rb:294:322
cucumber features/nodes.feature:543:563:579

Also your features should be shorter than that :)

RSpec supports a one-liner syntax for setting an expectation on the subject:

describe Array do
  describe "when first created" do
    it { should be_empty }
  end
end

The example description "it should be empty" will be defined automat...

To test whether two arrays have the same elements regardless of order, RSpec 1 and 2 give you the =~ matcher:

actual_array.should =~ expected_array

With RSpec 3's expect s...

You can usually just use the eq matched to compare two numbers:

expect(deal.total).to eq(120)

If the actual value is a BigDecimal, you might have issues when you match it against a Float:

expect(deal.total_price).to eq(1200.99...

RSpec provides a nice diff when certain matchers fail.

Here is an example where this diff is helpful while comparing two hashes:

{a:1}.should match(a:1, b:2)

Failure/Error: {a:1}.should match(a:1, b:2)
  expected {:a=>1} to match {:a=>1, :b...
