使用赛普拉斯选择下拉列表项 [英] select dropdownlist item using cypress

问题描述

我需要使用cypress测试angularjs应用程序的下拉列表.

I need to test a dropdown on angularjs application using cypress.

我需要单击一个下拉列表，然后从下拉列表中选择或单击一个项目.我尝试如下所示，它只能在一个实例上使用，而不能在其他情况下使用，因为第二个get()方法中的ID号随着其动态生成而不断变化.这不是带有html中选项的标准选择.

I would need to click on a dropdown and select or click an item from the dropdownlist. I tried as below which worked for one instance but not other time because the id number in the second get() method keeps changing as its dynamically generated. This is not a standard select with options as in html.

1)无论如何，我是否可以在每个选项上设置唯一属性，然后仅选择所需的选项，还是可以仅基于列表项的描述进行选择?我该怎么办?

1) Is there anyway I can set an unique attribute on each option and just select the required one or can I just select based on the description of the list item? How can I do that?

2)以下是测试下拉列表的正确方法吗?我确定还有比这更好的方法了吗?

2) Is the following right way of testing for a dropdown? I am sure there could be better way than this?

任何人都可以帮忙

cy.get('[name="countries"]').click().get.('[id="selection_option_375"]').click()

推荐答案

材料设计选择和赛普拉斯

这是与 Access元素相同的基本问题其父项被隐藏-cypress.io ，除了这个问题是angularjs + md-select，而这个问题是angular + mdc-select.

This is the same basic problem as Access element whose parent is hidden - cypress.io, except this question is angularjs + md-select and that question was angular + mdc-select.

尽管如此，两个版本的 material design select 使用相同的技巧来使父控件在打开选项后不可见(通过将width和height设置为0).

Nevertheless, the two versions of material design select use the same trick of making the parent control invisible (by setting width and height to 0) after clicking it to open the options.

柏树不允许点击选项，因为它认为选项是不可见的，因为父级是不可见的.

cypress will not allow a click of an option, because it think options are invisible because the parent is invisible.

解决方法是使用.then()访问未包装的列表项，然后使用 jquery 单击选择它，而不是 cypress 单击.

The work around is to use .then() to get access to the unwrapped list item, and use jquery click to select it instead of cypress click.

我已经在Angular 5设置上对其进行了测试，并且由于问题的相似性，希望它可以与AngularJS设置一起使用.

I have tested it on an Angular 5 setup, and because of the similarity of the problem expect it to work with an AngularJS setup.

带有md-select的AngularJS

describe('Testing material design select', function() {

  it('selects an option by click sequence (fails due to visibility issue)', function() {

    const doc = cy.visit('http://localhost:4200');
    cy.get('[name="countries"]').click();
    cy.get('md-option').contains('Country seven').click();

  });

  it('selects an option by click sequence', function() {

    const doc = cy.visit('http://localhost:4200')
    cy.get('[name="countries"]').click()
    cy.get('md-option').contains('Country seven').then(option => {

      // Confirm have correct option
      cy.wrap(option).contains('Country seven');  

      option[0].click();  // this is jquery click() not cypress click()

      // After click, md-select should hold the text of the selected option
      cy.get('[name="countries"]').contains('Country seven')  
    });
  });

});

Angular 2+，具有mdc-select

describe('Testing material design select', function() {

  it('selects an option by click sequence (fails due to visibility issue)', function() {

    const doc = cy.visit('http://localhost:4200');
    cy.get('[name="countries"]').click();
    cy.get('mdc-select-item').contains('Country seven').click();

  });

  it('selects an option by click sequence', function() {

    const doc = cy.visit('http://localhost:4200')
    cy.get('[name="countries"]').click()
    cy.get('mdc-select-item').contains('Country seven').then(option => {

      // Confirm have correct option
      cy.wrap(option).contains('Country seven');

      option[0].click();

      // After click, mdc-select should hold the text of the selected option
      cy.get('[name="countries"]').contains('Country seven');
    });
  });

});
