在 Qunit 测试中触发 JavaScript 个事件

Question

我正在尝试测试当用户单击我的表单时，现有的错误消息将会消失。出于某种原因，最后一次测试失败了，我不确定为什么。我是 jQuery 和 Qunit 的新手。

     equal($('.has-error').is(':visible'), false);
});

 test("errors not be hidden unless there is a keypress", function() {
      equal($('.has-error').is(':visible'), true);

test("errors should be hidden on click", function() {
     $('input[name="text"]').click();
     equal($('.has-error').is(':visible'), false);
 });

</script>

</html>

list.js

 jQuery(document).ready(function ($) {
     $('input[name="text"]').on('keypress', function() {
         $('.has-error').hide();
     });

     $('input[name="text"]').on('click', function() {
         $('.has-error').hide();

     });
 })

Answer 1

function setupModule() {
    $('input[name="text"]').on('click', function() {
         $('.has-error').hide();
    })
    $('input[name="text"]').on('keypress', function() {
        $('.has-error').hide();
    });
}

module('tests', {setup:setupModule});

test("errors should be hidden on key press", function() {
     $('input[name="text"]').trigger('keypress')
     equal($('.has-error').is(':visible'), false);
});

 test("errors not be hidden unless there is a keypress", function() {
     equal($('.has-error').is(':visible'), true);
 });


test("errors should be hidden on click", function() {
     $('input[name="text"]').click()
     equal($('.has-error').is(':visible'),false);
 });

Answer 2

我就是这样工作的。

/* ./inventory.js */
var hide_error = function () {
  $('input').on("keypress", function() {
    $( ".has-error" ).hide();
  });
}

/* ./tess.js */
QUnit.module( "module A ", {
  before: hide_error
});

QUnit.test("errors not be hidden unless keypresses", function ( assert ) {
  assert.equal( $('.has-error').is(':visible'), true, "Not Hidden" );
});

QUnit.test("errors should be hidden on keypresses", function ( assert ) {
  $('input').trigger("keypress");
  assert.equal( $(".has-error").is(':visible'), false, "Hidden" );
});
