BrowserVersion (HtmlUnit 4.18.0 API)

java.lang.Object
- org.htmlunit.BrowserVersion

All Implemented Interfaces:

Serializable
```
public final class BrowserVersion
extends Object
implements Serializable
```
Objects of this class represent one specific version of a given browser. Predefined constants are provided for common browser versions.
You can create a different browser setup by using the BrowserVersionFactory.
```
         final String applicationName = "APPNAME";
         final String applicationVersion = "APPVERSION";
         final String userAgent = "USERAGENT";
 
```
```
         final BrowserVersion browser =
                 new BrowserVersion.BrowserVersionBuilder(BrowserVersion.FIREFOX)
                     .setApplicationName(applicationName)
                     .setApplicationVersion(applicationVersion)
                     .setUserAgent(userAgent)
                     .build();
 
```
But keep in mind this new one still behaves like an FF, only the stuff reported to the outside is changed. This is more or less the same you can do with real browsers installing plugins like UserAgentSwitcher.
