Rspec & Rails: undefined method `to' for true:TrueClass

I'm trying to test one of my boolean string methods but I am getting the bellow error:

undefined method `to' for true:TrueClass

describe 'is_tall?' do

  it "should return true for a tall user" do
    expect(tall_user_string.is_tall?.to be_truthy)
  end

  it "should return false for a short user" do
    expect(user_string.is_tall?.to be_falsey)
  end

end

Any ideas?

You have a small typo, you need to close parentheses earlier:

describe 'is_tall?' do
  it "should return true for a tall user" do
    expect(tall_user_string.is_tall?).to be_truthy
  end

  it "should return false for a short user" do
    expect(user_string.is_tall?).to be_falsey
  end
end

And if you like William Shakespeare you can also write it like this:

describe 'is_tall?' do
  it "should return true for a tall user" do
    expect(tall_user_string.is_tall?).to be
  end

  it "should return false for a short user" do
    expect(user_string.is_tall?).not_to be
  end
end

The to call should follow the expect(), not the real method. Change

describe 'is_tall?' do

  it "should return true for a tall user" do
    expect(tall_user_string.is_tall?.to be_truthy)
  end

  it "should return false for a short user" do
    expect(user_string.is_tall?.to be_falsey)
  end

end

to

describe 'is_tall?' do

  it "should return true for a tall user" do
    expect(tall_user_string.is_tall?).to be_truthy
  end

  it "should return false for a short user" do
    expect(user_string.is_tall?).to be_falsey
  end

end
