Cypress web自动化4-操作页面元素(Actions行为事件)

前言

ui自动化操作页面上的元素，常用的方法就那么几个，输入文本，点击元素，清空文本，点击按钮。
还有一些特殊的checkbox,radio,滚动条等。

.type()

往输入框输入文本元素

<form>
              <div class="form-group">
                <label for="email1">Email address</label>
                <input type="email" class="form-control action-email" id="email1" placeholder="Email">
              </div>
              <div class="form-group">
                <label>Disabled Textarea</label>
                <textarea class="form-control action-disabled" disabled="disabled"></textarea>
              </div>
            </form>

cy.get('.action-email')
  .type('fake@email.com').should('have.value', 'fake@email.com')

  // .type() with special character sequences
  .type('{leftarrow}{rightarrow}{uparrow}{downarrow}')
  .type('{del}{selectall}{backspace}')

  // .type() with key modifiers
  .type('{alt}{option}') //these are equivalent
  .type('{ctrl}{control}') //these are equivalent
  .type('{meta}{command}{cmd}') //these are equivalent
  .type('{shift}')

  // Delay each keypress by 0.1 sec
  .type('slow.typing@email.com', { delay: 100 })
  .should('have.value', 'slow.typing@email.com')

cy.get('.action-disabled')
  // Ignore error checking prior to type
  // like whether the input is visible or disabled
  .type('disabled error checking', { force: true })
  .should('have.value', 'disabled error checking')

.focus()

要聚焦DOM元素，请使用.focus（）命令

<form>
              <div class="form-group">
                <label for="password1" style="color: orange;">Password</label>
                <input type="password" class="form-control action-focus focus" id="password1" placeholder="Password">
              </div>
            </form>

cy.get('.action-focus').focus()
  .should('have.class', 'focus')
  .prev().should('have.attr', 'style', 'color: orange;')

.blur()

判断输入框失去焦点时候，按钮的颜色

<div class="form-group">
                <label for="fullName1" style="color: red;">Full Name</label>
                <input type="text" class="form-control action-blur error" id="fullName1" placeholder="Enter your name">
              </div>

cy.get('.action-blur').type('About to blur').blur()
  .should('have.class', 'error')
  .prev().should('have.attr', 'style', 'color: red;')

.clear()

清空DOM元素

cy.get('.action-clear').type('Clear this text')
  .should('have.value', 'Clear this text')
  .clear()
  .should('have.value', '')

.submit()

提交form表单

<form class="action-form">
              <div class="form-group">
                <label for="couponCode1" val="HALFOFF">Coupon Code</label>
                <input type="text" class="form-control" id="couponCode1">
              </div>
              <button type="submit" class="btn btn-primary">Submit</button>
            </form>

cy.get('.action-form')
  .find('[type="text"]').type('HALFOFF')
cy.get('.action-form').submit()
  .next().should('contain', 'Your form has been submitted!')

.click()

点击DOM元素

cy.get('.action-btn').click()

// clicking in the center of the element is the default
cy.get('#action-canvas').click()

cy.get('#action-canvas').click('topLeft')
cy.get('#action-canvas').click('top')
cy.get('#action-canvas').click('topRight')
cy.get('#action-canvas').click('left')
cy.get('#action-canvas').click('right')
cy.get('#action-canvas').click('bottomLeft')
cy.get('#action-canvas').click('bottom')
cy.get('#action-canvas').click('bottomRight')

// .click() accepts a an x and y coordinate
// that controls where the click occurs :)
cy.get('#action-canvas')
  .click(80, 75)
  .click(170, 75)
  .click(80, 165)
  .click(100, 185)
  .click(125, 190)
  .click(150, 185)
  .click(170, 165)

// click multiple elements by passing multiple: true
cy.get('.action-labels>.label').click({ multiple: true })

// Ignore error checking prior to clicking
cy.get('.action-opacity>.btn').click({ force: true })

.dblclick()

双击 DOM 元素

cy.get('.action-div').dblclick().should('not.be.visible')
cy.get('.action-input-hidden').should('be.visible')

.rightclick()

右击 DOM 元素

cy.get('.action-div').rightclick().should('not.be.visible')
                cy.get('.action-input-hidden').should('be.visible')

.check()

检查 checkbox or radio 选项框

// By default, .check() will check all
// matching checkbox or radio elements in succession, one after another
cy.get('.action-checkboxes [type="checkbox"]').not('[disabled]')
  .check().should('be.checked')

cy.get('.action-radios [type="radio"]').not('[disabled]')
  .check().should('be.checked')

// .check() accepts a value argument
cy.get('.action-radios [type="radio"]')
  .check('radio1').should('be.checked')

// .check() accepts an array of values
cy.get('.action-multiple-checkboxes [type="checkbox"]')
  .check(['checkbox1', 'checkbox2']).should('be.checked')

// Ignore error checking prior to checking
cy.get('.action-checkboxes [disabled]')
  .check({ force: true }).should('be.checked')

cy.get('.action-radios [type="radio"]')
  .check('radio3', { force: true }).should('be.checked')

.uncheck()

检查checkbox or radio 未被选中

// By default, .uncheck() will uncheck all matching
// checkbox elements in succession, one after another
cy.get('.action-check [type="checkbox"]')
  .not('[disabled]')
  .uncheck().should('not.be.checked')

// .uncheck() accepts a value argument
cy.get('.action-check [type="checkbox"]')
  .check('checkbox1')
  .uncheck('checkbox1').should('not.be.checked')

// .uncheck() accepts an array of values
cy.get('.action-check [type="checkbox"]')
  .check(['checkbox1', 'checkbox3'])
  .uncheck(['checkbox1', 'checkbox3']).should('not.be.checked')

// Ignore error checking prior to unchecking
cy.get('.action-check [disabled]')
  .uncheck({ force: true }).should('not.be.checked')

.select()

select 选项框

<form>
              <select class="form-control action-select">
                <option>--Select a fruit--</option>
                <option value="fr-apples">apples</option>
                <option value="fr-oranges">oranges</option>
                <option value="fr-bananas">bananas</option>
              </select>

              <select class="form-control action-select-multiple" multiple="true">
                <option value="fr-apples">apples</option>
                <option value="fr-oranges">oranges</option>

              </select>
            </form>

// Select option(s) with matching text content
cy.get('.action-select').select('apples')

cy.get('.action-select-multiple')
.select(['apples', 'oranges', 'bananas'])

// Select option(s) with matching value
cy.get('.action-select').select('fr-bananas')

cy.get('.action-select-multiple')
  .select(['fr-apples', 'fr-oranges', 'fr-bananas'])

.scrollIntoView()

内嵌滚动条滑动,三种情况：左右滑动，上下滑动，同时可以左右上下滑动

<div class="well">
            <div id="scroll-horizontal" style="height: 300px; width: 300px; overflow: auto;">
              <div style="width: 1000px; position: relative;">
                Horizontal Scroll
                <button class="btn btn-danger" style="position: absolute; top: 0; left: 500px;">I'm Here</button>
              </div>
            </div>

            <div id="scroll-vertical" style="height: 300px; width: 300px; overflow: auto;">
              <div style="height: 1000px; position: relative;">
                Vertical Scroll
                <button class="btn btn-danger" style="position: absolute; top: 500px; left: 0">I'm Here</button>
              </div>
            </div>

            <div id="scroll-both" style="height: 300px; width: 300px; overflow: auto;">
              <div style="width: 1000px; height: 1000px; position: relative;">
                Both Scroll
                <button class="btn btn-danger" style="position: absolute; top: 500px; left: 500px">I'm Here</button>
              </div>
            </div>
          </div>

cy.get('#scroll-horizontal button')
  .should('not.be.visible')

// scroll the button into view, as if the user had scrolled
cy.get('#scroll-horizontal button').scrollIntoView()
  .should('be.visible')

cy.get('#scroll-vertical button')
  .should('not.be.visible')

// Cypress handles the scroll direction needed
cy.get('#scroll-vertical button').scrollIntoView()
  .should('be.visible')

cy.get('#scroll-both button')
  .should('not.be.visible')

// Cypress knows to scroll to the right and down
cy.get('#scroll-both button').scrollIntoView()
  .should('be.visible')

cy.scrollTo()

浏览器自带的滚动条

// if you chain .scrollTo() off of cy, we will
// scroll the entire window
cy.scrollTo('bottom')

cy.get('#scrollable-horizontal').scrollTo('right')

// or you can scroll to a specific coordinate:
// (x axis, y axis) in pixels
cy.get('#scrollable-vertical').scrollTo(250, 250)

// or you can scroll to a specific percentage
// of the (width, height) of the element
cy.get('#scrollable-both').scrollTo('75%', '25%')

// control the easing of the scroll (default is 'swing')
cy.get('#scrollable-vertical').scrollTo('center', { easing: 'linear' })

// control the duration of the scroll (in ms)
cy.get('#scrollable-both').scrollTo('center', { duration: 2000 })

.trigger()

在DOM元素上触发事件

<form>
            <fieldset>
              <label for="range-input">Range Input</label>
              <input class="trigger-input-range" name="range-input" type="range" value="0">
              <p>0</p>
            </fieldset>
          </form>

cy.get('.trigger-input-range')
  .invoke('val', 25)
  .trigger('change')
  .get('input[type=range]').siblings('p')
  .should('have.text', '25')
