RSpec: 3 things you should stop writing in example descriptions

it "adds certain value"
it "returns correct result"
it "fails"
it "returns formatted string"
it "returns correct url"
it "is ok"

it "changes @scheduled_on"
it "assigns @todos"

it "returns time in 24-hour format" do
  expect(...).to eq "9:25"
end

it "strips leading zeroes" do
  expect(foo(" 9:25 ")).to eq "9:25"
end
