java - 单击 id 定位的元素但结果仍然不正确

Question

我正在 Google 翻译页面上测试 Selenium-Webdriver。我想做的是:

1. 查看输入语言是否已显示
2. 如果出现，是否会被选中？如果没有选择它。
3. 如果不存在，请打开更多语言表。选择(单击)表格上的语言。
4. 查看输出语言是否已呈现
5. 如果出现，是否会被选中？如果没有选择它。
6. 如果不存在，请打开更多语言表。选择(单击)表格上的语言。
7. 最后翻译并检查结果

我对案例 1 没有任何问题:输入和输出语言已经呈现，结果符合预期。但对于情况 2:输出语言尚未呈现并且必须在表格上选择，就会出现问题。 选择的语言不正确(例如，我选择挪威语，但最终会选择萨摩亚语)。 选择输入使用相同的方式进行选择，但根本不返回任何问题。

我的代码如下

我会做这样的事情。您应该专注于创建只执行单一操作的函数，以便拥有可以轻松用于各种测试的可重用代码。

这是我的功能

static public String getTranslatedText()
{
    new WebDriverWait(driver, 10).until(new ExpectedCondition<Boolean>()
    {
        public Boolean apply(WebDriver d)
        {
            return d.findElement(By.id("result_box")).getText().length() != 0;
        }
    });
    return driver.findElement(By.id("result_box")).getText();
}

static public void setSourceLanguage(String lang)
{
    // see if the desired language is already selected
    if (!driver.findElement(By.cssSelector("#gt-lang-src div.jfk-button-checked")).getText().equals(lang))
    {
        // open the Source language dropdown
        driver.findElement(By.id("gt-sl-gms")).click();

        // select the desired language
        driver.findElement(By.xpath("//div[@id='gt-sl-gms-menu']//div[text()='" + lang + "']")).click();
    }
}

static public void setTargetLanguage(String lang)
{
    // see if the desired language is already selected
    if (!driver.findElement(By.cssSelector("#gt-lang-tgt div.jfk-button-checked")).getText().equals(lang))
    {
        // open the Source language dropdown
        driver.findElement(By.id("gt-tl-gms")).click();

        // select the desired language
        driver.findElement(By.xpath("//div[@id='gt-tl-gms-menu']//div[text()='" + lang + "']")).click();
    }
}

static public void translateText(String text)
{
    driver.findElement(By.id("source")).sendKeys(text);
}

一个简单的测试看起来像

driver.get("https://translate.google.com/");
setSourceLanguage("English");
setTargetLanguage("Lao");
translateText("This is some text");
System.out.println(getTranslatedText());

完成这个练习后，我注意到文本翻译后的 URL 是 https://translate.google.com/#en/lo/This%20is%20some%20text 。我假设您没有测试谷歌翻译，而只是想要翻译？如果确实如此，您只需根据语言标记导航到 URL 并传入所需的文本即可。

URL 的格式为

https://translate.google.com/#<source language token>/<target language token>/<text to be translated>

所以越南语到英语就是

https://translate.google.com/#vi/en/This%20is%20some%20text

越南语到挪威语将是

https://translate.google.com/#vi/no/This%20is%20some%20text

然后您所要做的就是获取翻译后的文本。
