Aspects of the present invention include methods, apparatuses and systems that may be used for radio frequency and performance testing of communication equipment in a telecommunications network. According to one aspect of the invention, received data may be discarded during a test whenever a device being testing is unable to store the data, for example in a buffer. According to another aspect of the invention, the device being tested will provide data for transmission processing whenever there is an opportunity during the testing to transmit data, thus allowing the device to be aggressive in its data transmission.
