A method for arranging test stages in a production line for the assembling and testing of wireless communications devices comprises: determining a plurality of tests for testing an assembled wireless communication device; allocating each test requiring a physical actuation or mechanical dynamics for testing the assembled wireless communication device from the plurality of tests to an interactive test stage in the production line; and, allocating each remaining test requiring no physical actuation or mechanical dynamics for testing from the plurality of tests between the interactive test stage and a non-interactive test stage.
