Htmlunit driver download

WebDriver has a built-in implementation of Firefox driver Gecko Driver. For other browsers, you need to plug-in their browser specific drivers to communicate and run the test. Most commonly used WebDriver's include:.

For instance, if you want to use the browser driver in java, use the java bindings. It supports data structures like object and array. So, it is easy to write and read data from JSON. Selenium uses drivers, specific to each browser in order to establish a secure connection with the browser without revealing the internal logic of browser's functionality.

The browser driver is also specific to the language used for automation such as Java, C , etc. When we execute a test script using WebDriver, the following operations are performed internally.

Verbal Ability. Before understanding the details of these configurations, let's first understand what benefits does running a test in headless mode provides? Even though running the Selenium test provides these benefits, certain limitations are also attached to the same. A few of them are as listed below:. As we discussed above, Selenium WebDriver provides various drivers and configurations which help in running the Selenium test cases in headless mode.

Let's understand a few of them in the following sections:. HtmlUnitDriver is currently the fastest and most lightweight implementation of WebDriver. HtmlUnitDriver is a well known headless browser driver and has many advantages -. HTMLUnitDriver is available as an external dependency and requires you to add the library explicitly. Note: In the earlier versions of Selenium before version 2.

While this driver is still supported, it is now a separate dependency and uses the Html Unit framework. These dependencies need to add in the project in the same way as other jars add. After downloading the jar file, follow the below steps to add the jar to the Eclipse project,.

Once you have the jar added to the Eclipse project, you can import the class " org. HtmlUnitDriver " into your test code by adding the below line -. The above syntax will construct a new instance with JavaScript disabled, and the default browser version. If your application needs some of the JavaScript functionalities, you can enable the same, with the configurations as mentioned in the following article:.

It means in the above code, if you try to execute JavaScript , an error will be thrown, stating that JavaScript is not enabled. To create a driver instance with JavaScript enabled, you can use the constructor HtmlUnitDriver boolean enable javascript and set the value as true as shown below. Now that we have created the instance of the WebDriver let's see how we can use the same in our Selenium test scripts for running the tests in a headless mode.

When you run the code, you will not see any browser on the screen, but as the execution completes, it will print the title of the page as shown below -. As highlighted in the above image, the title of the page prints as "ToolsQA".

This browser was by default on your machine. If you want to execute the test cases in a specific browser version also, you can also do the same with the help of HTMLUnitDriver. Let's understand how we can achieve the same:. HtmlUnitDriver allows you to select the version of the browser that you would like to run your tests. The main supported browsers are Chrome, Firefox, and Internet Explorer.

We can use the different versions of the browser by passing the values in the constructor that will create a new instance with the specified version of the browser as in the code below -. Again, you will not see any browser on the screen when the above code executes, and the page title will print in the output:. Step 2 Run the code. You will observer no browser is launched and results are shown in console. The latest release of PhatomJS has integrated GhostDriver and there is no need to separately install it.

Step 2 Download PhantomJS here. Add the jar to your project. Step 6 Run the code. You will observe the output is shown in console and no browser is launched. Click on Allow Access. To test application rapidly in various browsers and without any visual interruption, headless browser Testing is used.

Due to its speed, accuracy and easy to access features, HTML unit driver and PhantomJS are gaining popularity for headless browser testing.

By following some simple steps you get to know how easily these tools can be integrated with other tools and can execute the test code. Skip to content.
