#Go言語 `-count=1`オプションを指定する。 ```console:go\shelp\stestの一部 The rule for a match in the cache is that the run involves the same test binary and the flags on the command line come entirely from a restricted set of 'cacheable' test flags, defined as -benchtime, -cpu, -list, -parallel, -run, -short, and -v. If a run of go test has any test or non-test flags outside this set, the result is not cached. To disable test caching, use any test flag or argument other than the cacheable flags. The idiomatic way to disable test caching explicitly is to use -count=1. Tests that open files within the package's source root (usually $GOPATH) or that consult environment variables only match future runs in which the files and environment variables are unchanged. A cached test result is treated as executing in no time at all, so a successful package test result will be cached and reused regardless of -timeout setting. ```
