Provided are a double-cavity micro-fluidic chip having a reaction cavity and a test cavity and used for nucleic acid test, and a test method thereof. A fluid channel is provided between the reaction cavity and the test cavity, and only one exhaust channel is provided. The combination of the fluid channel and the exhaust channel can automatically provide resistance for a sample entering the test cavity from the reaction cavity, thereby achieving a controllable transfer of the sample between the reaction cavity and the test cavity.
