Can the submitted invention patent be approved if it has not been verified by actual test?

Your application for a patent for invention can be approved as long as the technical scheme is feasible and meets the three requirements of the patent. The requirement of "three natures" does not include that an application for a patent for invention-creation must be verified by experiments. Therefore, it is ok to submit an invention patent without verification. As for authorization, it depends on whether your invention can pass the third trial. Invention patents must pass substantive examination.
