使用赛普拉斯选择下拉列表项

Question

我需要使用cypress测试angularjs应用程序的下拉列表。

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。我想下面这是因为在第二个get（）方法的ID号不断变化作为它的动态生成的工作了一个实例，但没有其他时间。这不是带有html中选项的标准选择。

1）无论如何，是否可以在每个选项上设置唯一属性，然后选择所需的选项，还是可以仅基于列表项的描述进行选择？我怎样才能做到这一点？

2）是否有以下正确的下拉列表测试方法？我敢肯定还有比这更好的方法吗？

请谁能帮忙

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

Answer 1

材料设计选择和赛普拉斯

这与父元素被隐藏的Access元素cypress.io是相同的基本问题，除了这个问题是angularjs + md-select，而这个问题是angular + mdc-select。

尽管如此，两个版本的材料设计选择使用相同的技巧，在单击父控件以打开选项后，使父控件不可见（通过将width和height设置为0）。

赛普拉斯不允许单击选项，因为它认为选项是不可见的，因为父级是不可见的。

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

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。

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')  
    });
  });

});

具有dc-select的Angular 2+

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');
    });
  });

});

Answer 2

对于 Angular 使用材料下拉列表：

cy.get('mat-select').contains('CA').click({ force: true })
