需要单击Salesforce中的"联系人"选项卡，以获取错误"Cannot read properties of undefined (reading 'defaultView')"

Question

通过自动化脚本想要点击Contacts tab in Salesforce。但无法做到这一点。

我尝试过以下三种方案，但都不起作用。这个代码一直工作到昨天中午，晚上收到上面提到的错误：

1.

//driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
WebElement contacts=driver.findElement(By.xpath("//div[@class='slds-context-bar']/one-app-nav-bar[@class='slds-grid slds-has-flexi-truncate']/nav[@class='slds-context-bar__secondary navCenter']/div/one-app-nav-bar-item-root[1]/a[@title='Contacts']/span[@class='slds-truncate' and text()='Contacts']"));
//driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
contacts.click();

//new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//nav[@class='slds-context-bar__secondary navCenter']/div/one-app-nav-bar-item-root[2]/a[@title='Contacts']"))).click();

//driver.findElement(By.xpath("//nav[@class='slds-context-bar__secondary navCenter']/div/one-app-nav-bar-item-root[2]/a[@title='Contacts']")).click();

Answer 1

Selenium中有4种点击方式。

我将使用此xpath

//span[text()='Contacts']/parent::a[contains(@href,'lightning/o/Contact/home')]

代码试用1:

Thread.sleep(5);
driver.findElement(By.xpath("//span[text()='Contacts']/parent::a[contains(@href,'lightning/o/Contact/home')]")).click();

代码试用2:

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//span[text()='Contacts']/parent::a[contains(@href,'lightning/o/Contact/home')]"))).click();

代码试用3:

Thread.sleep(5);
WebElement button = driver.findElement(By.xpath("//span[text()='Contacts']/parent::a[contains(@href,'lightning/o/Contact/home')]"));
((JavascriptExecutor)driver).executeScript("arguments[0].click();", button);

代码试用4:

Thread.sleep(5);
WebElement button  = driver.findElement(By.xpath("//span[text()='Contacts']/parent::a[contains(@href,'lightning/o/Contact/home')]"));
new Actions(driver).moveToElement(button).click().build().perform();

PS:如果我们在HTML DOM中是否有唯一条目，请检查dev tools(谷歌铬)。

检查步骤：

Press F12 in Chrome->转到element部分->进行CTRL + F->然后粘贴xpath，看看您想要的element是否通过1/1匹配节点突出显示。
