The primary new feature in Selenium 2.0 is the integration of the WebDriver API. WebDriver is designed to provide a simpler, more concise programming interface in addition to addressing some
一些初級的新的特性在2.0中是集成在WebDriver API中的。 Webdriver會提供一個簡便的、更簡潔的編程接口，除了處理一些限制的API。
limitations in the Selenium-RC API. Selenium-WebDriver was developed to better support dynamic web pages where elements of a page may change without the page itself being reloaded.
Selenium-WebDriver是為了更好地支持開發動態web頁面,頁面元素沒有被重新加載頁面本身可能會改變。
WebDriver’s goal is to supply a well-designed object-oriented API that provides improved support for modern advanced web-app testing problems.
WebDriver的目標是提供一個精心設計的面向對象的API,提供了現代先進的web測試問題改進的支持。
Selenium-WebDriver makes direct calls to the browser using each browser’s native support for automation. How these direct calls are made, and the features they support depends on the
Selenium-WebDriver使直接調用瀏覽器使用每個瀏覽器的本地支持自動化。如何將這些直接調用,和它們所支持的特性取決于您所使用的瀏覽器。

每個瀏覽器的司機的信息在本章后面提供。每個瀏覽器的驅動信息將在后邊章節中提供。
For those familiar with Selenium-RC, this is quite different from what you are used to. Selenium-RC worked the same way for each supported browser. It ‘injected’ javascript functions into the

browser’s built in support for automation.
You may, or may not, need the Selenium Server, depending on how you intend to use Selenium-WebDriver. If you will be only using the WebDriver API you do not need the Selenium-Server. If your browser and tests will all run on the same machine, and your tests only use the WebDriver API, then you do not need to run the Selenium-Server; WebDriver will run the browser directly.
There are some reasons though to use the Selenium-Server with Selenium-WebDriver.
You are using Selenium-Grid to distribute your tests over multiple machines or virtual machines (VMs).
您正在使用selenium grid將測試分配到多臺機器上或虛擬機(vm)。
You want to connect to a remote machine that has a particular browser version that is not on your current machine.
你想要連接到遠程計算機,一個特定的瀏覽器版本,不是你現在的機器上。
You are not using the Java bindings (i.e. Python, C#, or Ruby) and would like to use HtmlUnit Driver
你不使用Java綁定(例如Python,c#或Ruby),愿用HtmlUnit驅動。
To install Selenium means to set up a project in a development so you can write a program using Selenium. How you do this depends on your programming language and your development environment.
安裝Selenium意味著建立一個項目在 開發工具，這樣你可以使用Selenium寫一個程序。你如何做到這一點取決于你的編程語言和開發環境。
The easiest way to set up a Selenium 2.0 Java project is to use Maven. Maven will download the java bindings (the Selenium 2.0 java client library) and all its dependencies, and will create the
最容易的方法是建立一個Selenium2.0java項目用Maven.Maven將下載java綁定(Selenium2.0 java客戶端庫)及其所有依賴項。并將為你創建一個項目，用Maven pom.xml (project configuration) file.

一旦你這樣做,你可以將maven項目導入到你喜歡的IDE,IntelliJ IDEA或Eclipse。
First, create a folder to contain your Selenium project files. Then, to use Maven, you need a pom.xml file. This can be created with a text editor. We won’t teach the details of pom.xml files or for
首先， 創建一個文件夾包含你的Selenium項目文件 。 然后，你用Maven ，你需要一個pom.xml file。 這將創建一個文本編輯器，我們會提供一些 細節針對pom.xml files
using Maven since there are already excellent references on this. Your pom.xml file will look something like this. Create this file in the folder you created for your project.
使用Maven,因為已經有很好的參考。xml文件將會看起來像這樣。創建這個文件在您為您的項目創建的文件夾。
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>MySel20Proj</groupId> <artifactId>MySel20Proj</artifactId> <version>1.0</version> <dependencies> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>2.53.0</version> </dependency> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-htmlunit-driver</artifactId> <version>2.20</version> </dependency> </dependencies> </project>
Be sure you specify the most current version. At the time of writing, the version listed above was the most current, however there were frequent releases immediately after the release of Selenium 2.0. Check the Maven download page for the current release and edit the above dependency accordingly.
確保您指定最新版本。在寫這篇文章的時候,上面列出的版本是最新的,然而之后有頻繁的發布Selenium .檢查Maven下載頁面的當前版本和編輯上述相應的依賴.
Now, from a command-line, CD into the project directory and run maven as follows.
現在，從一個命令行，cd命令進入項目目錄 并運行Maven按照如下。
mvn clean install
This will download Selenium and all its dependencies and will add them to the project.
這將下載Selenium及其所有依賴項并將它們添加到項目中。
Finally, import the project into your preferred development environment. For those not familiar with this, we’ve provided an appendix which shows this.
最后,將項目導入到您的開發環境。對于那些不熟悉這個,我們提供一個顯示了這個附錄。

本節介紹WebDriver API和幫助你開始熟悉它。首先建立一個WebDriver項目如果你還沒有準備好。
This was described in the previous section, Setting Up a Selenium-WebDriver Project.
這是在前一節中描述
Once your project is set up, you can see that WebDriver acts just as any normal library: it is entirely self-contained, and you usually don’t need to remember to start any additional processes or
一旦設置您的項目,您可以看到WebDriver行為就像任何正常庫:它是完全獨立的，你通常不需要記住任何額外的流程或開始或

Note: additional steps are required to use ChromeDriver, Opera Driver, Android Driver and iOS Driver
You’re now ready to write some code. An easy way to get started is this example, which searches for the term “Cheese” on Google and then outputs the result page’s title to the console.
你現在準備編寫一些代碼。一個簡單的方法開始是這個例子中,這在谷歌上搜索“奶酪”這個詞,然后輸出結果頁面的標題到控制臺。
package org.openqa.selenium.example;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;
public class Selenium2Example {
public static void main(String[] args) {
// Create a new instance of the Firefox driver
// Notice that the remainder of the code relies on the interface,
// not the implementation.
WebDriver driver = new FirefoxDriver();
// And now use this to visit Google
driver.get("http://www.google.com");
// Alternatively the same thing can be done like this
// driver.navigate().to("http://www.google.com");
// Find the text input element by its name
WebElement element = driver.findElement(By.name("q"));
// Enter something to search for
element.sendKeys("Cheese!");
// Now submit the form. WebDriver will find the form for us from the element
element.submit();
// Check the title of the page
System.out.println("Page title is: " + driver.getTitle());
// Google's search is rendered dynamically with JavaScript.
// Wait for the page to load, timeout after 10 seconds
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return d.getTitle().toLowerCase().startsWith("cheese!");
}
});
// Should see: "cheese! - Google Search"
System.out.println("Page title is: " + driver.getTitle());
//Close the browser
driver.quit();
}
}In upcoming sections, you will learn more about how to use WebDriver for things such as navigating forward and backward in your browser’s history, and how to test web sites that use frames and windows. We also provide a more thorough discussions and examples.
在接下來的部分中,您將學習更多關于如何使用WebDriver向前和向后導航,例如在你的瀏覽器的歷史，以及如何測試web站點使用幀和窗戶。我們還提供一個更詳細的討論和示例。
The first thing you’re likely to want to do with WebDriver is navigate to a page. The normal way to do this is by calling “get”:
你可能想要做的第一件事和WebDriver導航到一個頁面。正常的方法是通過調用“get”:
driver.get("http://www.google.com");Dependent on several factors, including the OS/Browser combination, WebDriver may or may not wait for the page to load. In some circumstances, WebDriver may return control before the page has finished, or even started, loading. To ensure robustness, you need to wait for the element(s) to exist in the page using Explicit and Implicit Waits.
取決于幾個因素,包括操作系統/瀏覽器組合,WebDriver可能會或可能不會等待頁面加載。在某些情況下,WebDriver可能返回控制頁面完成之前,甚至開始裝載。為了確保加載速度,您需要等待頁面中的元素(s)存在使用顯式和隱式等待。
定位用戶界面元素(WebElements)
Locating elements in WebDriver can be done on the WebDriver instance itself or on a WebElement. Each of the language bindings expose a “Find Element” and “Find Elements” method. The first returns a WebElement object otherwise it throws an exception. The latter returns a list of WebElements, it can return an empty list if no DOM elements match the query.
WebDriver定位元素可以在完成本身或WebElement WebDriver實例。每種語言綁定公開“Find Element”和“Find Elements”方法。第一個返回一個WebElement對象否則它將拋出一個異常。后者WebElements返回一個列表,它能返回一個空列表如果沒有DOM元素匹配查詢。
The “Find” methods take a locator or query object called “By”. “By” strategies are listed below.
“Find”的方法來定位器或查詢對象稱為“By”。下面列出了“By”策略。
This is the most efficient and preferred way to locate an element. Common pitfalls that UI developers make is having non-unique id’s on a page or auto-generating the id, both should be avoided. A class on an html element is more appropriate than an auto-generated id.
這是最有效的和首選方法來定位一個元素。常見的陷阱,UI開發人員在一個頁面上有非唯一id或自動生成的id,都應該避免.一個類一個html元素上比一個自動生成的id更合適。
Example of how to find an element that looks like this:
如何找到一個元素的例子是這樣的:
<div id="coolestWidgetEvah">...</div>
WebElement element = driver.findElement(By.id("coolestWidgetEvah"));“Class” in this case refers to the attribute on the DOM element. Often in practical use there are many DOM elements with the same class name, thus finding multiple elements becomes the more practical option over finding the first element.
“類”在這種情況下是指DOM元素上的屬性.通常在實際使用DOM元素有很多相同的類名,從而發現多個元素變得更實用的選擇在找到第一個元素。
Example of how to find an element that looks like this:
<div class="cheese"><span>Cheddar</span></div><div class="cheese"><span>Gouda</span></div>
List<WebElement> cheeses = driver.findElements(By.className("cheese"));The DOM Tag Name of the element.
DOM元素的標記名稱。
Example of how to find an element that looks like this:
<iframe src="..."></iframe>
WebElement frame = driver.findElement(By.tagName("iframe"));Find the input element with matching name attribute.找到匹配的名稱屬性的輸入元素。
Example of how to find an element that looks like this:
<input name="cheese" type="text"/>
WebElement cheese = driver.findElement(By.name("cheese"));Find the link element with matching visible text.找到匹配的可見文本鏈接元素。
Example of how to find an element that looks like this:
<a >cheese</a>>
WebElement cheese = driver.findElement(By.linkText("cheese"));Find the link element with partial matching visible text.發現部分匹配可見文本鏈接元素。
Example of how to find an element that looks like this:
<a >search for cheese</a>>
WebElement cheese = driver.findElement(By.partialLinkText("cheese"));Like the name implies it is a locator strategy by css. Native browser support is used by default, so please refer to w3c css selectors for a list of generally available css selectors. If a browser does not have native support for css queries, then Sizzle is used. IE 6,7 and FF3.0 currently use Sizzle as the css query engine.
喜歡這個名字意味著它是一個由css定位策略。在默認情況下使用本機瀏覽器支持,所以請參閱w3c css選擇器投入使用css選擇器的列表。如果瀏覽器不支持css的查詢,然后使用Sizzle。IE 6、7和FF3.0目前使用Sizzle作為css查詢引擎。
Beware that not all browsers were created equal, some css that might work in one version may not work in another.
注意,并不是所有的瀏覽器都是平等的,一些css,可能工作在一個版本可能不會在另一個工作。
Example of to find the cheese below:
<div id="food"><span class="dairy">milk</span><span class="dairy aged">cheese</span></div>
WebElement cheese = driver.findElement(By.cssSelector("#food span.dairy.aged"));At a high level, WebDriver uses a browser’s native XPath capabilities wherever possible. On those browsers that don’t have native XPath support, we have provided our own implementation. This can lead to some unexpected behaviour unless you are aware of the differences in the various xpath engines.
在高級別上,WebDriver盡可能使用瀏覽器的原生XPath功能。在那些沒有原生XPath支持的瀏覽器,我們提供自己的實現。這可能導致一些意想不到的行為,除非你知道各種xpath引擎的差異。
This is a little abstract, so for the following piece of HTML:
<input type="text" name="example" /> <INPUT type="text" name="other" />
List<WebElement> inputs = driver.findElements(By.xpath("http://input"));The following number of matches will be found
Sometimes HTML elements do not need attributes to be explicitly declared because they will default to known values. For example, the “input” tag does not require the “type” attribute because it defaults to “text”. The rule of thumb when using xpath in WebDriver is that you should not expect to be able to match against these implicit attributes.
有時HTML元素不需要顯式聲明屬性,因為他們將默認為已知值。例如,“輸入”標簽不需要“type”屬性,因為它默認為“文本”.WebDriver使用xpath時的經驗法則是,你不應該期望能夠匹配這些隱式屬性。
You can execute arbitrary javascript to find an element and as long as you return a DOM Element, it will be automatically converted to a WebElement object.
你可以執行任意javascript來找到一個元素,只要你返回一個DOM元素,它將自動轉換為WebElement對象。
Simple example on a page that has jQuery loaded:
jQuery加載的頁面上的簡單的例子:
WebElement element = (WebElement) ((JavascriptExecutor)driver).executeScript("return $('.cheese')[0]");Finding all the input elements to the every label on a page:
找到所有的輸入元素上的每個標簽頁:
List<WebElement> labels = driver.findElements(By.tagName("label"));
List<WebElement> inputs = (List<WebElement>) ((JavascriptExecutor)driver).executeScript(
"var labels = arguments[0], inputs = []; for (var i=0; i < labels.length; i++){" +
"inputs.push(document.getElementById(labels[i].getAttribute('for'))); } return inputs;", labels);We’ve already seen how to enter text into a textarea or text field, but what about the other elements? You can “toggle” the state of checkboxes, and you can use “click” to set something like an OPTION tag selected. Dealing with SELECT tags isn’t too bad:
我們已經看到如何在文本區域輸入文本或文本字段,但是其他元素呢?你可以“切換”復選框的狀態,你可以使用“點擊”設置這樣一個選項標簽選擇。處理選擇標簽并不是太糟了:
WebElement select = driver.findElement(By.tagName("select"));
List<WebElement> allOptions = select.findElements(By.tagName("option"));
for (WebElement option : allOptions) {
System.out.println(String.format("Value is: %s", option.getAttribute("value")));
option.click();
}This will find the first “SELECT” element on the page, and cycle through each of its OPTIONs in turn, printing out their values, and selecting each in turn. As you will notice, this isn’t the most efficient way of dealing with SELECT elements. WebDriver’s support classes include one called “Select”, which provides useful methods for interacting with these.
這將會發現第一個頁面上的“選擇”元素,并通過它的每個周期選項,打印出它們的值,并選擇每個。你會注意到,這并不是最有效的方式處理選擇元素。WebDriver類包括一個稱為“選擇”的支持,這對與這些交互提供了有用的方法。
Select select = new Select(driver.findElement(By.tagName("select")));
select.deselectAll();
select.selectByVisibleText("Edam");This will deselect all OPTIONs from the first SELECT on the page, and then select the OPTION with the displayed text of “Edam”.
Once you’ve finished filling out the form, you probably want to submit it. One way to do this would be to find the “submit” button and click it:
driver.findElement(By.id("submit")).click();Alternatively, WebDriver has the convenience method “submit” on every element. If you call this on an element within a form, WebDriver will walk up the DOM until it finds the enclosing form and then calls submit on that. If the element isn’t in a form, then the NoSuchElementException will be thrown:
element.submit();
窗口和框架之間的移動
Some web applications have many frames or multiple windows. WebDriver supports moving between named windows using the “switchTo” method:
一些web應用程序有很多幀或多個窗口。WebDriver支持移動名為windows之間使用“switchTo”的方法:
driver.switchTo().window("windowName");All calls to driver will now be interpreted as being directed to the particular window. But how do you know the window’s name? Take a look at the javascript or link that opened it:
所有調用驅動程序現在將被視為被定向到特定的窗口。但是你怎么知道窗口的名字嗎?看一下打開它的javascript或鏈接:
<a href="somewhere.html" target="windowName">Click here to open a new window</a>
Alternatively, you can pass a “window handle” to the “switchTo().window()” method. Knowing this, it’s possible to iterate over every open window like so:
另外,您可以通過“窗口句柄”到“switchTo().window()方法。知道了這一點,可以遍歷所有打開的窗口如下所示:
for (String handle : driver.getWindowHandles()) {
driver.switchTo().window(handle);
}You can also switch from frame to frame (or into iframes):
您還可以切換從幀到幀(或iframes):
driver.switchTo().frame("frameName");彈出對話框
Starting with Selenium 2.0 beta 1, there is built in support for handling popup dialog boxes. After you’ve triggered an action that opens a popup, you can access the alert with the following:
從Selenium2.0 beta 1,內建支持處理彈出對話框。觸發一個動作之后,打開一個彈出,您可以訪問以下警告:
Alert alert = driver.switchTo().alert();
This will return the currently open alert object. With this object you can now accept, dismiss, read its contents or even type into a prompt. This interface works equally well on alerts, confirms, and prompts. Refer to the JavaDocs or RubyDocs for more information.
這將返回當前打開警報對象。這個對象現在可以接受,解雇,閱讀其內容,甚至類型到一個提示。這個接口同樣適用于警報、確認和提示。參考JavaDocs或RubyDocs獲得更多信息。
導航:歷史和位置
Earlier, we covered navigating to a page using the “get” command ( driver.get("http://www.example.com")) As you’ve seen, WebDriver has a number of smaller, task-focused interfaces, and navigation is a useful task. Because loading a page is such a fundamental requirement, the method to do this lives on the main WebDriver interface, but it’s simply a synonym to:
早些時候,我們覆蓋導航到一個頁面使用“get”命令(driver.get(“http://www.example.com”)如您所見,WebDriver有許多小,以任務為中心的界面,和導航是一個有用的任務。因為加載一個頁面是一個基本的要求,
這個方法做這個生活在主WebDriver接口,但它只是一個同義詞:
driver.navigate().to("http://www.example.com");To reiterate: “navigate().to()” and “get()” do exactly the same thing. One’s just a lot easier to type than the other!
重申：“navigate().to()” and “get()”做的是相同的事情，只是另一個更容易一點。
The “navigate” interface also exposes the ability to move backwards and forwards in your browser’s history:
“導航”界面也暴露前后移動的能力在你的瀏覽器的歷史:
driver.navigate().forward(); driver.navigate().back();
Please be aware that this functionality depends entirely on the underlying browser. It’s just possible that something unexpected may happen when you call these methods if you’re used to the behaviour of one browser over another.
請注意,此功能完全取決于底層的瀏覽器。只是可能會發生一些意想不到的事當你調用這些方法如果你使用一個瀏覽器的行為。
Before we leave these next steps, you may be interested in understanding how to use cookies. First of all, you need to be on the domain that the cookie will be valid for. If you are trying to preset cookies before you start interacting with a site and your homepage is large / takes a while to load an alternative is to find a smaller page on the site, typically the 404 page is small (http://example.com/some404page)
在我們離開這些步驟之前,你可能有興趣了解如何使用cookie。首先,你需要在域的Cookie的有效期,如果你想預定cookie在你開始與網站交互和你的主頁是大/需要一段時間來加載另一種方法是在網站上找到一個小頁面,通常404頁的小
// Go to the correct domain
driver.get("http://www.example.com");
// Now set the cookie. This one's valid for the entire domain
Cookie cookie = new Cookie("key", "value");
driver.manage().addCookie(cookie);
// And now output all the available cookies for the current URL
Set<Cookie> allCookies = driver.manage().getCookies();
for (Cookie loadedCookie : allCookies) {
System.out.println(String.format("%s -> %s", loadedCookie.getName(), loadedCookie.getValue()));
}
// You can delete cookies in 3 ways
// By name
driver.manage().deleteCookieNamed("CookieName");
// By Cookie
driver.manage().deleteCookie(loadedCookie);
// Or all of them
driver.manage().deleteAllCookies();修改用戶代理
This is easy with the Firefox Driver:
FirefoxProfile profile = new FirefoxProfile();
profile.addAdditionalPreference("general.useragent.override", "some UA string");
WebDriver driver = new FirefoxDriver(profile);拖拽
Here’s an example of using the Actions class to perform a drag and drop. Native events are required to be enabled.
這里有一個例子使用行為的類進行拖拽。本地事件需要啟用。
WebElement element = driver.findElement(By.name("source"));
WebElement target = driver.findElement(By.name("target"));
(new Actions(driver)).dragAndDrop(element, target).perform();Driver的細節和權衡
WebDriver is the name of the key interface against which tests should be written, but there are several implementations. These include:
WebDriver是測試的關鍵接口的名字應該寫,但有幾個實現。這些包括:
This is currently the fastest and most lightweight implementation of WebDriver. As the name suggests, this is based on HtmlUnit. HtmlUnit is a java based implementation of a WebBrowser without a GUI. For any language binding (other than java) the Selenium Server is required to use this driver.
這是目前最快的和最輕量級WebDriver的實現。顧名思義,這是基于HtmlUnit。HtmlUnit是一個基于java的瀏覽器沒有GUI的實現。對任何語言綁定(除了java)Selenium服務器需要使用這個驅動程序。
使用
WebDriver driver = new HtmlUnitDriver();
Fastest implementation of WebDriver最快的實現WebDriver
A pure Java solution and so it is platform independent.純Java的解決方案,所以它是平臺獨立的。
Supports JavaScript支持JS
Emulates other browsers’ JavaScript behaviour (see below)模擬其他瀏覽器的JavaScript行為(見下文)
None of the popular browsers uses the JavaScript engine used by HtmlUnit (Rhino). If you test JavaScript using HtmlUnit the results may differ significantly from those browsers.
沒有一個流行的瀏覽器使用使用的JavaScript引擎HtmlUnit(犀牛)。如果您使用的測試JavaScript HtmlUnit結果從這些瀏覽器可能差別很大。
When we say “JavaScript” we actually mean “JavaScript and the DOM”. Although the DOM is defined by the W3C each browser has its own quirks and differences in their implementation of
當我們說“JavaScript”實際上意味著“JavaScript和DOM”。雖然由W3C DOM定義每個瀏覽器都有自己的怪癖和差異實施，DOM和JavaScript是如何進行交互的。
the DOM and in how JavaScript interacts with it. HtmlUnit has an impressively complete implementation of the DOM and has good support for using JavaScript, but it is no different from any
HtmlUnit有一個令人印象深刻的完整實現使用JavaScript DOM和具有良好的支持,但是它對其他瀏覽器沒有任何區別。
other browser: it has its own quirks and differences from both the W3C standard and the DOM implementations of the major browsers, despite its ability to mimic other browsers.
它有自己的怪癖和差異來自W3C標準和主流瀏覽器的DOM實現,盡管其模仿其他瀏覽器的能力。
With WebDriver, we had to make a choice; do we enable HtmlUnit’s JavaScript capabilities and run the risk of teams running into problems that only manifest themselves there, or do we leave
WebDriver,我們不得不做出選擇;我們讓HtmlUnit的JavaScript功能和運行團隊遇到的風險問題,只有表現,
JavaScript disabled, knowing that there are more and more sites that rely on JavaScript? We took the conservative approach, and by default have disabled support when we use HtmlUnit. With
知道越來越多的依賴于JavaScript的網站嗎?我們采取了保守的方法,當我們使用HtmlUnit默認情況下禁用支持
each release of both WebDriver and HtmlUnit, we reassess this decision: we hope to enable JavaScript by default on the HtmlUnit at some point.
WebDriver和HtmlUnit每個版本,我們評估這個決定:我們希望在HtmlUnit默認啟用JavaScript。
If you can’t wait, enabling JavaScript support is very easy:
HtmlUnitDriver driver = new HtmlUnitDriver(true);
This will cause the HtmlUnit Driver to emulate Firefox 3.6’s JavaScript handling by default.
Controls the Firefox browser using a Firefox plugin. The Firefox Profile that is used is stripped down from what is installed on the machine to only include the Selenium WebDriver.xpi (plugin). A few settings are also changed by default (see the source to see which ones) Firefox Driver is capable of being run and is tested on Windows, Mac, Linux. Currently on versions 3.6, 10, latest - 1, latest
控制了Firefox瀏覽器使用Firefox插件。Firefox配置文件使用的是剝奪了從什么是安裝在機器上只包括硒WebDriver。xpi(插件)。一些默認設置也改變了Firefox(見源代碼看到哪些)驅動程序可以運行和測試的在Windows,Mac,Linux。目前版本3.6,最新10 - 1,最新的。
