你如何测试空输入字段？

I'm trying to test to see if an input field matches one of my factories where the field is empty.

我正在尝试测试输入字段是否与我的工厂中的哪个字段为空。

address => {:first_name => '', :last_name => ''}

When checking for what is in the input field I've been using this:

当检查输入字段中的内容时,我一直在使用它:

assert_select '#first_name[value=?]', address.first_name

Except this does not work if the first name is blank. I'll get this error and the test fails.

如果第一个名称为空,则不起作用。我会收到此错误,测试失败。

Expected at least 1 element matching "#first_name[value='']", found 0.
<false> is not true.

This makes sense because the code generated will not have the value attribute. Is there a better way to verify the value of an input field?

这是有道理的,因为生成的代码不具有value属性。有没有更好的方法来验证输入字段的值?

As of now to test for this I can check if the address field is blank then check if there is an input field without a value attribute. But this is messy and verbose.

到目前为止测试这个我可以检查地址字段是否为空,然后检查是否有没有值属性的输入字段。但这很麻烦而且冗长。

Example of a universal check that works but is lengthy:

通用检查的示例有效但很长:

if address.first_name.blank?
  assert_select '#first_name[value]', 0
  assert_select '#first_name[type=text]', 1
else
  assert_select '#first_name[value=?]', address.first_name
end

Maybe you can use:

也许你可以使用:

assert_select "#first_name" do
  assert_select "[value=?]", address.first_name unless address.first_name.blank?
end

I don't think I can get it any shorter. If it is a recurring pattern in your test case, you could extract it to a custom assertion:

我认为我不能更短。如果它是测试用例中的重复模式,则可以将其解压缩为自定义断言:

def assert_has_value_unless_blank(selector, value)
  assert_select selector do
    assert_select "[value=?]", value unless value.blank?
  end
end

assert_has_value_unless_blank "#first_name", address.first_name
