摘要： Provided is a test apparatus comprising a plurality of testing sections and a synchronizing section that synchronizes operation of at least two testing sections among the plurality of testing sections. Each testing section transmits a synchronization standby command to the synchronizing section when a predetermined condition is fulfilled during execution of the corresponding program and the testing section enters a synchronization standby state, and on a condition that the synchronization standby commands have been received from all of one or more predetermined testing sections among the plurality of testing sections, the synchronizing section supplies a synchronization signal, which ends the synchronization standby state, in synchronization to two or more predetermined testing sections among the plurality of testing sections.
