An apparatus for testing a wiring harness grommet sealing is provided to check the waterproof state of the grommet sealing by detecting the leakage of the carbon dioxide gas which is supplied by the gas supplying device through the grommet sealing. A testing apparatus for wiring harness grommet sealing includes a gas chamber(10), a checking chamber(14), and a controlling unit(16). The gas chamber has a grommet sealing unit(2) and is connected with a pair of gas supplying devices(6,8) at one side. The checking chamber has a connecting pipe(4) and is coupled with a gas sensor(12) which detects the gas supplied by the gas supplying devices. The gas supplying devices include a gas tank to store carbon dioxide gas and a solenoid valve connected to a discharge port of the gas tank to be controlled by the controlling unit. The controlling unit is connected to the gas sensor and the solenoid valve and outputs the signal when the gas sensor detects the gas. A display device is installed on one side of the controlling unit to display the state of gas detection.
