A testing method and machine for automatic adjustment of the conveying means for printed circuit boards (20) in a test machine of modular type, comprising a test module (1), a loading module (2), and an unloading module (3), wherein respective moveable rails (110, 111; 210, 211; 310, 311)are provided to support the rails (110, 111) are moved toward each other, with an independent movement, and temporarily stopped on detection of corresponding stops (26) indicative of the width of the printed circuit board (20) to be tested, then withdrawn by a fixed, pre-established distance, so as to be disposed in the correct conveying position, the rails (210, 211; 310, 311) of the other modules (2, 3) being brought toward each other and stopped on detection of fixed stops in the test module (1), so as to be disposed in perfect alignment with the rails (110, 111).
