The invention belongs to the field of oil exploration and development, and discloses a device for visually testing multi-component bubble point pressure and a method for testing the bubble point pressure. The device comprises a visual PVT test unit and a post-processing unit. The method for testing the bubble point pressure comprises a method for testing the bubble point pressure of the oil-gas-water three-phase multi-component and a method for visually testing the bubble point pressure of the oil-gas two-phase multi-component. The method can also record the multiphase mixing process in real time and capture the moment when the first bubble point appears, so that the experiment precision is ensured, and the method is more in line with the actual production. And meanwhile, an experiment post-treatment device and a cleaning process are designed, so that the experiment precision is ensured. When the visual testing method for testing the bubble point pressure of the oil-gas-water three-phase multi-component is ad
