Question

在运行量角器-黄瓜框架时获取无效的定位器。我已经建立了具有所需依赖关系的量角器黄瓜框架。

在出现此错误之前，量角器无法找到特征文件的步骤定义。因此，我将黄瓜版本从4.2.1降级到1.3.3，即使我已经为按钮类（.button-large.button-primary提供了有效的定位器），我也能找到步骤定义，但得到了无效的定位器错误。 has-shield.has-shadow）。


export default function() {
  this.Given(/^I am on the "([^]*)" page$/, { timeout: 40 * 1000 }, async function homepage(page) {
      console.log(page);
      await browser.get('http://www.angularjs.org');
      const ele = await element(by.css('.button-large.button-primary.has-shield.has-shadow'));
      return element(ele).click();
    });
}```

Getting below error
``` TypeError: Invalid locator
         at Object.check [as checkedLocator] (/mnt/c/Angular/node_modules/protractor/node_modules/selenium-webdriver/lib/by.js:275:9)
         at thenableWebDriverProxy.findElements (/mnt/c/Angular/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver.js:1041:18)

Protractor should run above code as it is valid locator.

Answer 1

发生这种情况是因为您试图将ElementFinder传递给element函数。

在此行：

      return element(ele).click();

尝试一下：

  export default function() {
    this.Given(/^I am on the "([^]*)" page$/, { timeout: 40 * 1000 }, async function homepage(page) {
      console.log(page);
      await browser.get('http://www.angularjs.org');
      return await element(by.css('.button-large.button-primary.has-shield.has-shadow')).click();
    });
  }

或者如果您想作为示例：

 export default function() {
    this.Given(/^I am on the "([^]*)" page$/, { timeout: 40 * 1000 }, async function homepage(page) {
      console.log(page);
      await browser.get('http://www.angularjs.org');
      const ele = await element(by.css('.button-large.button-primary.has-shield.has-shadow'));
      return ele.click();
    });
  }

Answer 2

尝试以下选项

const ele = element(by.css('.button-large.button-primary.has-shield.has-shadow'));
await ele.click();
