“指定”方法对红宝石的作用是什么？

Question

So I'm working through chapter 6 of Michael Hartl's tutorial and I came across this code

describe "with invalid password" do
  let(:user_for_invalid_password) { found_user.authenticate("invalid") }

  it { should_not eq user_for_invalid_password }
  specify { expect(user_for_invalid_password).to be_false }

What does the last line do? Specifically, what does specify do? I couldn't find anything on it through google.

Answer 1

specify is the same as it - some people think it reads better.

For a detailed example that shows the different context you may choose to use it, have a look at this example Difference between an it block and a specify block in RSpec

Answer 2

specify is simply the alias of it . You can check here

you can check more here Difference between an it block and a specify block in RSpec

The last line just check it is false or not if it you supply invalid password.
