Remove direct support for HtmlUnit

[klieber]

HtmlUnit is no longer bundled with Selenium and it has not be the default WebDriver for a long time now so rather than including it as an extra dependency it makes more sense to just remove direct support for it. That being said it is still possible to configure your project to work with HtmlUnit just with a bit more configuration.

Here is an example:

<plugin>
  <groupId>com.github.searls</groupId>
  <artifactId>jasmine-maven-plugin</artifactId>
  <version>${jasmine-maven-plugin.version}</version>
  <executions>
    <execution>
      <goals>
        <goal>test</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <webDriverClassName>org.openqa.selenium.htmlunit.HtmlUnitDriver</webDriverClassName>
    <webDriverCapabilities>
      <capability>
        <name>browserName</name>
        <value>htmlunit</value>
      </capability>
      <capability>
        <name>browserVersion</name>
        <value>firefox</value>
      </capability>
    </webDriverCapabilities>
  </configuration>
  <dependencies>
    <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>htmlunit-driver</artifactId>
      <version>2.43.1</version>
    </dependency>
  </dependencies>
</plugin>
