<file>:<line_number> (line number appended to file path)

To run one or more examples or groups, you can append the line number to the path, e.g.

$ rspec path/to/example_spec.rb:37

Background​

Given a file named "example_spec.rb" with:

RSpec.describe "outer group" do

  it "first example in outer group" do

  end

  it "second example in outer group" do

  end

  describe "nested group" do

    it "example in nested group" do

    end

  end

end

And a file named "example2_spec.rb" with:

RSpec.describe "yet another group" do
  it "first example in second file" do
  end
  it "second example in second file" do
  end
end

And a file named "one_liner_spec.rb" with:

RSpec.describe 9 do

  it { is_expected.to be > 8 }

  it { is_expected.to be < 10 }

end
