// Runs before every test module in this package (wired in through `--preload`
// on the package's `deno-test` task). It points `DASHBOARD_CACHE_DIR` at a
// directory made for this process, and removes that directory as the process
// unloads. The dashboard's stores keep their files under that variable, and
// fall back to the machine's temporary directory without it, where a test
// would read what an earlier run or a running dashboard left there. A value
// the environment already holds is replaced for the same reason.
//
// It also removes the variables that configure the dashboard's GitHub
// credentials. A test that wants one sets it, and a credential the shell
// happened to hold would otherwise reach GitHub, or take precedence over the
// one the test set.
