  browser.waitForElementVisible('.spacer-right big project-card-measure-secondary-info', 1000)
         .getText('.spacer-right big project-card-measure-secondary-info', (result) => {
         console.log(result)
       })

在控制台上不返回任何内容。文章源自玩技e族-https://www.playezu.com/179888.html 文章源自玩技e族-https://www.playezu.com/179888.html
