PROBLEM TO BE SOLVED: To obtain a method and an apparatus, for a corrosion resistance test, in which a corrosion state and an erosion state under various environments in various plants or the like can be reproduced stably and in which an obtained result can be reflected easily on a flow passage in a plant or the like. SOLUTION: In a gap-jet-method testing apparatus for high temperature and high pressure as a flow-passage corrosion resistance testing apparatus, a circulating flow passage 31 into which a test liquid is introduced is provided, a first member 41 (a holding part) which holds a test piece 100 inside the circulating flow passage 31 so as to be detachable is provided, and third members 43 (liquid port parts) which are arranged and installed so as to face a test face in such a way that the introduced test liquid comes into contact with the test face 101 on the held test piece 100 are provided. At least two liquid port parts are arranged and installed in series with the circulating flow passage 31. One is arranged and installed as a discharge port which discharges the test liquid in such a way that the flow direction of the introduced test liquid is nearly perpendicular to the test face 101, and the other is arranged and installed as a discharge port which discharges the test liquid in such a way that the flow direction of the introduced test liquid is nearly parallel to the test face 101.
