Scenarios

standard examples

Given

a file named "example_spec.rb" with:

require "rspec/expectations"

describe 9 do

  it "should be > 8" do
    9.should be > 8
  end

  it "should be < 10" do
    9.should be < 10
  end

  it "should be 3 squared" do
    9.should be 3*3
  end

end

When

I run rspec example_spec.rb --line_number 5 --format doc

Then

the examples should all pass

And

the output should contain "should be > 8"

But

the output should not contain "should be < 10"

And

the output should not contain "should be 3*3"

When

I run rspec example_spec.rb --line_number 5 --line_number 9 --format doc

Then

the examples should all pass

And

the output should contain "should be > 8"

And

the output should contain "should be < 10"

But

the output should not contain "should be 3*3"
