如何立即执行承诺

需要执行承诺的帮助。代码：如何立即执行承诺

it('[TEST-1] Log in with invalid credentials-wrong email', function() { 
    //LogIn 
    browser.logger.info("[ENTRY] - Username: " + browser.params.Adenity.loginInfo[2].username); 
    element(by.id('js-input-email')).sendKeys(browser.params.Adenity.loginInfo[2].username); 
    expect(element(by.id('js-input-email')).getAttribute('value')).toEqual(browser.params.Adenity.loginInfo[2].username); 
    element(by.id('js-input-email')).getAttribute('value').then(function(pom) { 
     if (pom == browser.params.Adenity.loginInfo[2].username) 
      browser.logger.info("Username populated succesfully"); 
     else 
      browser.logger.info("Username not populated succesfully"); 
    }); 
    browser.logger.info("[ENTRY] - Password: " + browser.params.Adenity.loginInfo[2].password); 
    element(by.id('js-input-password')).sendKeys(browser.params.Adenity.loginInfo[2].password); 
    expect(element(by.id('js-input-password')).getAttribute('value')).toEqual(browser.params.Adenity.loginInfo[2].password); 
    element(by.id('js-input-password')).getAttribute('value').then(function(pom) { 
     if (pom == browser.params.Adenity.loginInfo[2].password) 
      browser.logger.info("Password populated succesfully"); 
     else 
      browser.logger.info("Password not populated succesfully"); 
    }); 
});

实际结果：

[INFO] protractorLog4js - [ENTRY] - Username: [email protected] 
[INFO] protractorLog4js - [ENTRY] - Password: Test1234 
[INFO] protractorLog4js - Username populated succesfully 
[INFO] protractorLog4js - Password populated succesfully

我想要的结果：

[INFO] protractorLog4js - [ENTRY] - Username: [email protected] 
[INFO] protractorLog4js - Username populated succesfully 
[INFO] protractorLog4js - [ENTRY] - Password: Test1234 
[INFO] protractorLog4js - Password populated succesfully

我不知道我应该如何解决这个问题，所以任何帮助表示赞赏。

['.resolve']（HTTPS ：//developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/resolve）？ –

你**不能让异步代码神奇地同步。查看[这个问题]的答案（http://stackoverflow.com/questions/14220321/how-do-i-return-the-response-from-an-asynchronous-call），它讨论了一系列异步操作。就你而言，你正在寻找一个关于串联（不平行）的答案。您还需要了解您的测试框架如何处理异步测试。 –

就像Javascript一样令人惊叹，它不能做时间旅行：p –

的SendKeys也返回一个承诺，从而保证事情发生的顺序您希望您的代码必须看起来更像：

element(by.id('js-input-email')).sendKeys(browser.params.Adenity.loginInfo[2].username).then(function() { 
    return element(by.id('js-input-email')).getAttribute('value'); 
}).then(function(pom) { 
    if (pom == browser.params.Adenity.loginInfo[2].username) 
     browser.logger.info("Username populated succesfully"); 
    else 
     browser.logger.info("Username not populated succesfully"); 

    browser.logger.info("[ENTRY] - Password: " + browser.params.Adenity.loginInfo[2].password); 
    return element(by.id('js-input-password')).sendKeys(browser.params.Adenity.loginInfo[2].password) 
}).then(function() { 
    expect(element(by.id('js-input-password')).getAttribute('value')).toEqual(browser.params.Adenity.loginInfo[2].password); 
    return element(by.id('js-input-password')).getAttribute('value') 
}).then(function(pom){ 
    if (pom == browser.params.Adenity.loginInfo[2].password) 
     browser.logger.info("Password populated succesfully"); 
    else 
     browser.logger.info("Password not populated succesfully"); 
});
