NightwatchJS не может ПолучитьЗначение в разделе

Question

я следующая команда встраивается в разделе:

verify: function (input) { 
    this 
     .waitForElementVisible('@value'); 
    this 
     .getValue('.keystone-body form .field-type-text[for="name"] input[name="name"]', function(result) { 
      this.assert.equal(result.value, input.value); 
     }); 
    this 
     .getValue('.keystone-body form .field-type-text[for="name"]', function(result) { 
      console.log('***result: ' + JSON.stringify(result)); 
     }); 
    this 
     .getValue('@value', function (result) { 
      console.log('***result: ' + JSON.stringify(result)); 
     }); 
    return this; 
}, 

Как вы можете видеть в журналах Селена, все четыре вызовов функции относятся к одному дереву селектора (3-й один является на самом деле представление дерева селектора, которое приводит к тому, что исключение произойдет на 4-м). Первые три работы просто прекрасны. Однако четвертый не создает и генерирует исключение в журналах ниже. Обратите внимание, что в третьем я использовал тот же селектор, вызывающий исключение, и отлично работает. Я пошел на страницу, где это происходит используется следующий запрос (такой же, как 3-й и 4-запросов выше) и работает отлично, а также:

document.querySelector('.keystone-body form .field-type-text[for="name"]')

Я пошёл вокруг этого и, похоже, не могу прийти к первопричине. Любые указатели будут очень благодарны!

Answer 1

Оказалось, что страница имела очень встроенную небольшую форму, которая каким-то образом отбрасывала селектор сгенерированной секцией.
