That's an outdated patch - i've just looked at that file locally and have:

class IssueHistoryTest extends SoapBase {
	/**
	 * A test case that tests the following:
	 * 1. Creates a new issue
	 * 2. validates that history entry is present
	 */
	public f

I did try looking at specifying an additional php unit @ comment line to each function, which then got removed, so i'd guess it was from doing that, and I've since cleaned it up.
