Instance Method Details

#it_with(**lets, &block) ⇒ Object

Creates a nested context + example with ‘let` values defined from the arguments.

See also #its_block_with for a block form, and #instant_context for inline ‘context`+`let` definitions.

Examples:


subject { x + y }

it_with(x: 1, y: 2) { is_expected.to eq 3 }

# is equivalent to

context "with x=1, y=2" do
  let(:x) { 1 }
  let(:y) { 2 }

  it { is_expected.to eq 3 }
end
