The utility model provides a test tool used for circuit break tests or short circuit tests carried out on a capacitor in a circuit. The test tool comprises a first alternating current contactor, a second alternating current contactor, a first time relay, a second time relay and a switching device. A coil of the first time relay is in series connection with the switching device to form a first branch. A coil of the second time relay is in series connection with the switching device to form a second branch. The first branch is in parallel connection with the second branch. The switching device is used for respectively controlling on-off of the first time relay and the second time relay. A contact end of the first time relay and the coil of the first alternating current contactor are in series connection to form a third branch. A contact end of the second time relay is in series connection with the coil of the second alternating current contactor to form a fourth branch. The third branch is in parallel connection with the fourth branch. The contact end of the first alternating current contactor is used for being in parallel connection with a tested capacitor. The contact end of the second alternating current contactor is used for being in parallel connection with the tested capacitor. The test tool of the utility model is high in automation degree and high in test efficiency.
