Updating to eclipse 3 4
You can use either the Eclipse Marketplace or the update site: Go to the Test NG page on the Eclipse Market Place and drag the icon called "Install" onto your workspace.
You can also install older versions of the plug-ins here.
Note: The steps below are only valid for Eclipse versions prior to 3.4.
Method 2: Create a Remote Site using a link that points to a location where the GEF plug-in can be downloaded and installed.
