private void assertTimestampsEqualWithEpsilon ( long expected , long actual , int epsilon , String desc ) { assertTrue ( "Expected a " + desc + " time within " + epsilon + "ms of " + expected + " but got " + actual , Math . abs ( actual - expected ) < epsilon ) ; }
kinda like the junit asserts for doubles , which allows an " epsilon " but this is for integers , and with a specific description in the assert just for timestamps . all times are expected in milliseconds
