ruby-on-rails - Rspec & rails : undefined method `to' for true:TrueClass

Question

我正在尝试测试我的 bool 字符串方法之一，但出现以下错误:

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

有什么想法吗？

Answer 1

to 调用应该跟在 expect() 之后，而不是真正的方法。改变

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

到

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
