Question

我正在尝试使用Selenium和Cucumber实现自动化测试的方法，目前看起来像这样：

public By getFromAccountSelector() {
    try {
        return By.xpath("//ib-dropdown[@ng-model='model.from']");
    } catch (Exception exc) {
        return By.xpath("//ib-dropdown[@ng-model='data.account']");
    }
}

它应该做的是将Gherkin中的“fromAccount”一词映射到由各自的XPath表达式查找的HTML元素。如果该方法没有通过一个表达式找到该元素，那么它应该不会抛出通常在这种情况下抛出的org.openqa.selenium.NoSuchElementException，而是尝试使用下一个表达式进行搜索。

但是，无论我在catch块中放置什么，都会抛出org.openqa.selenium.NoSuchElementException。这就好像被忽略了一样。该计划甚至没有到达第二个街区。我试图将org.openqa.selenium.NoSuchElementException替换为catch，但行为保持不变。

造成这种情况的原因是什么？如何解决？

Answer 1

你在错误的地方捕捉它。真实的事情发生在CommonSeleniumStepDefinitions.java:206

中

By.xpath（）什么都不做，驱动程序使用它来访问元素。

Java没有在catch块中捕获异常
