1. A test assembly, characterized by comprising:
interfaces, wherein one end of the interfaces is configured to connect to a device under test, and the interfaces comprise at least a first interface and a second interface;
a first three-way valve, wherein the first three-way valve comprises a first cut-in valve, a first vent valve, and a first test valve, one end of the first interface is connected to the first cut-in valve, and the first vent valve lets in atmospheric air and is able to open and close;
a second three-way valve, wherein the second three-way valve comprises a second cut-in valve, a second vent valve, and a second test valve, one end of the second interface is connected to the second cut-in valve, and the second vent valve lets in atmospheric air and is able to open and close;
a manifold, wherein the first test valve is connected to the manifold and the second test valve is connected to the manifold; and
a sensor, wherein the manifold is connected to a test end of the sensor; and, wherein the test assembly further comprises a control unit configured to control the vent valve of each three-way valve to open and close, wherein when the control unit controls the first vent valve to open, the control unit controls the second vent valve to close, and when the control unit controls the second vent valve to open, the control unit controls the first vent valve to close.
