It is a convention to have assertEqual() assertions invoked with 'expected value' before 'actual value', or else the debug output may become very confusing. This patch fixes about 100 violations in current test cases where about 3580 assertEqual calls are made. Closes-Bug: 1259292 Change-Id: I2e0474d9821716baf35a3bbb2952c63a84749dd3
