WebDriver拾级而上·之十 封装与重用

WebDriver对页面的操作，需要找到一个WebElement，然后再对其进行操作，比较繁琐：

<wbr><wbr>// Find the text inputelement by its name</wbr></wbr>

<wbr><wbr></wbr></wbr> <wbr></wbr>WebElement element = driver.findElement(By.name("q"));

<wbr><span style="word-wrap:normal; word-break:normal; line-height:21px"><wbr><wbr></wbr></wbr></span><span style="word-wrap:normal; word-break:normal; line-height:21px"><wbr></wbr></span>// Enter something to search for</wbr>

<wbr><wbr></wbr></wbr> <wbr></wbr>element.sendKeys("Cheese!");

我们可以考虑对这些基本的操作进行一个封装，简化操作。比如，封装代码：

<wbr><wbr>protected void<span style="word-wrap:normal; word-break:normal; line-height:21px; color:rgb(14,1,254)">sendKeys</span>(By by, String value){</wbr></wbr>

<wbr><wbr><wbr><wbr><span style="word-wrap:normal; word-break:normal; line-height:21px; color:rgb(16,3,255)">driver.findElement(<span style="word-wrap:normal; word-break:normal; line-height:21px; color:rgb(34,177,76)">by</span>).sendKeys(<span style="word-wrap:normal; word-break:normal; line-height:21px; color:rgb(34,177,76)">value</span>);</span></wbr></wbr></wbr></wbr>

<wbr><wbr>}</wbr></wbr>

那么，在测试用例可以这样简化调用：

<wbr><wbr></wbr></wbr> <wbr></wbr> sendKeys(By.name("q"),"Cheese!");

看，这就简洁多了。

类似的封装还有：
