Bug 110331 add tests for import/export
I have written additional tests for import archive, export to file system and export to archive. And changed the import existing and import operation (file system) tests. This work required a change to the TarFile class in the ide plugin. Attachments to follow.
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/wizards/datatransfer/TarFile.java
public InputStream getInputStream(TarEntry entry) throws TarException, IOException {
		if(entryStream == null || !entryStream.skipToEntry(entry)) {
			InputStream in = new FileInputStream(file);
			
			try {
				in = new GZIPInputStream(in);
			} catch(IOException e) {
				in = new FileInputStream(file);
			}
			entryStream = new TarInputStream(in, entry) {
				public void close() {
					
				}
			};
		}
		if(entryStream == null) {
			System.out.println("huh?"); 
		}
		return entryStream;
	}
	/**
	 * Returns the path name of the file this archive represents.
	 * 
	 * @return path
	 */
	public String getName() {
		return file.getPath();
	}
}
