赛普拉斯:测试元素是否存在 [英] Cypress: test if element exists

问题描述

我是赛普拉斯的新手，我知道之前曾有人问过这个问题，但我仍然被困在这里！这是我写的:

I am new to cypress, I know that this question has been asked before but I am still stuck here! This is the what I have written:

 it("User can set certification for multiple users at once",()=>{
       cy.get(':nth-child(4) > .RadioButton__StyledRadioButton-sc-1j2qp2u-1').click(); //clicking Non-certified button
       const $el=Cypress.$('[class="Typography__StyledTypography-sc-153d8g4-0.jhYDmS.TrainingQueueListstyles__EmptyListMessage-sc-19yfim3-1.ihRiqU"]');
       cy.get("body").then($body =>{
        if ($body.find($el.length>0)) {
         cy.log('in if loop');
         cy.log($el.length);
         cy.get('.hZDZBR').should('not.exist');
         cy.get('input[id="selectAll"]').should('not.exist');
        } else {
        cy.log('in else loop');
        cy.log($el.length);
        cy.get('input[id="selectAll"]').click();
        cy.get('.hZDZBR').click();
      }
     })
    })

但是当找不到元素 $ el 时(它记录了正确的 $ el.length = 0 )，它仍然尝试执行if循环，而应该在else循环中...有关如何解决此问题的任何想法?谢谢！

But when the element $el is not found (and it logs $el.length=0 which is correct), it still tries to execute the if loop, whereas it should be in else loop...any ideas on how to resolve this?Thanks!

所以我再次更新了我的代码，因为这种情况($ body.find($ el.length> 0))总是评估为true，正如理查德·马特森(Richard Matsen)正确指出的那样.现在发生的事情是它计算长度为0，因此进入else循环，但是我可以在网页上看到该元素，但长度仍为0.这是什么原因，我该怎么办?

So I updated my code again because this condition ($body.find($el.length>0)) always evaluates to true as rightly pointed out by Richard Matsen. What happens now is that it calculates the length to be 0, and therefore enters else loop, but I can see the element on the web page and still it gets the length as 0..what is the reason and what can I do about it?

it("User can set certification for multiple users at once",()=>{
       cy.get(':nth-child(4) > .RadioButton__StyledRadioButton-sc-1j2qp2u-1').click(); //clicking Non-certified button
       const $el=Cypress.$('[class="Typography__StyledTypography-sc-153d8g4-0.jhYDmS.TrainingQueueListstyles__EmptyListMessage-sc-19yfim3-1.ihRiqU"]');
       cy.get("body").then($body =>{
        if ($body.find($el).length>0) {
         cy.log('in if loop');
         cy.log($body.find($el).length);
         cy.get('.hZDZBR').should('not.exist');
         cy.get('input[id="selectAll"]').should('not.exist');
        } else if($body.find($el).length==0){
        cy.log('in else loop');
        cy.log($body.find($el).length);
        cy.get('input[id="selectAll"]').click();
        cy.get('.hZDZBR').click();
      }
   })
 })

推荐答案

如何使用此功能

it("User can set certification for multiple users at once",()=>{
    cy.get(':nth-child(4) > .RadioButton__StyledRadioButton-sc-1j2qp2u-1').click(); //clicking Non-certified button
    const selector=".Typography__StyledTypography-sc-153d8g4-0.jhYDmS.TrainingQueueListstyles__EmptyListMessage-sc-19yfim3-1.ihRiqU";
    cy.get("body").then($body =>{
        const $el = $body.find(selector);
        if ($el) {
            cy.log('in if loop');
            cy.get('.hZDZBR').should('not.exist');
            cy.get('input[id="selectAll"]').should('not.exist');
        } else {
            cy.log('in else loop');
            cy.get('input[id="selectAll"]').click();
            cy.get('.hZDZBR').click();
        }
    })
})

我所做的一些更改是:

• 使用选择器而不是查询初始元素
• 查询回调中的实际元素
• 如果/其他基于该结果
