Question

对js / node.js不太熟悉。使用codeceptjs / puppeteer进行一些自动化测试。现在尝试在测试中编辑描述。但有时不存在描述-因此“编辑描述”按钮不存在-而是“添加描述”按钮。所以我写了一个if语句，指定了。但是代码只是将其翻转。语句是什么都无所谓，它仅移至下一行。当前if (desc)和if(!desc)都执行相同的功能-转到if语句的下一行。这会导致错误，因为已经有描述，因此“添加描述”按钮不可用。我不确定发生了什么。

Scenario('test something', (I, userLoginPage, FBPagePage) => {


    userLoginPage.validate();


    I.click('//*[@id="card_611"]');
       // clicks the card

    var desc = '//*[@id="show_card_description"]/section/button';
    // add description button
    // tried 'Add description' but the result was the same

    if (desc){
     // this is where the error happens. it simply looks for the add description button
     // no matter what button is there it decides to click the 'add description' button

        I.click('//*[@id="show_card_description"]/section/button');
    // click add desc button

        I.fillField('//*[@id="description_editor_container"]/div[2]/div[1]',
        'not admin user created this description thanks to automated testing');
    // types this stuff 
        I.click('//*[@id="description_editor_container"]/button[1]');
    // saves it 
        I.wait(1);
}

    I.click('//*[@id="show_card_description"]/section/h5/a');
    // click edit desc button if a description already exists
    I.fillField('//*[@id="description_editor_container"]/div[2]/div[1]', 'not admin user edited this description thanks to automated testing');
    I.click('//*[@id="description_editor_container"]/button[1]');


I.say('success!')
});

Answer 1

为您提供正确的上下文：您首先要问的是Node.js问题，而不是CodeceptJS或Puppeteer。

desc始终为true，因为您将其声明为字符串，所以无论您已经发现，if内的任何代码都将运行。

您可以使用类似的方法：

const numOfElements = await I.grabNumberOfVisibleElements('#show_card_description section button'); // Use CSS locator instead of Xpath for easier readability

console.log(numOfElements); // Debug

if(numOfElements === 1) {
   …
}

维护人员不支持在场景函数中使用常规功能文件的if语句，理由是由于意外结果，该语句是测试的不良做法，相反，您必须在自定义帮助程序文件中执行以下操作：

   /**
   * Checks the specified locator for existance, if it exists, return true
   * If it is not found log a warning and return false.
   */

  async checkElement(locator) 
  {
    let driver = this.helpers["Appium"].browser;
    let elementResult = await driver.$$(locator);
    if (elementResult === undefined || elementResult.length == 0) 
    {
      //console.log("Locator: " + locator + " Not Found");
      return false;
    } 
    else if (elementResult[0].elementId) 
    {
      //console.log("Locator: " + locator + " Found");
      return true;
    }
  }

CodeceptJS / Puppeteer无法识别“ if”语句
