#### Running doctest for testable docstring

There are two ways to test the code in the docstring locally:

1.  If you are only changing the docstring of a class/function/method, then you
    can test it by passing that file's path to

	//
	// setup creates a fake scavengeIndex that can be mutated and queried by
	// the functions it returns. Those functions capture the testing.T that
	// setup is called with, so they're bound to the subtest they're created in.
	//
	// Tests are then organized into test cases which mark some pages as
	// scavenge-able then try to find them. Tests expect that the initial

                        ctx.ApplyConfigOrFail(ctx, nil, mycfg)
                        // Do more stuff here.
                    })
            }
        })
}
```

Under the hood, calling `subtest.Run()` delegates to `t.Run()` in order to create a child `testing.T`.

### Parallel Tests

Many tests can take a while to start up for a variety of reasons, such as waiting for pods to start or waiting

			vcsTestTLSHost := os.Getenv("TESTGO_VCSTEST_TLS_HOST")
			vcsTestClient, err := vcstest.TLSClient(os.Getenv("TESTGO_VCSTEST_CERT"))
			if err != nil {
				fmt.Fprintf(os.Stderr, "loading certificates from $TESTGO_VCSTEST_CERT: %v", err)
			}
			var interceptors []web.Interceptor
			for _, host := range vcstest.Hosts {
				interceptors = append(interceptors,

# # whether the latter is stale.

	for _, s := range svcs {
		svcHost := string(s.Hostname)

		if _, ok := hostsFromGateways[svcHost]; ok {
			gwSvcs = append(gwSvcs, s)
		}
	}

	log.Debugf("GatewayServices: gateways len(services)=%d, len(filtered)=%d", len(svcs), len(gwSvcs))

	return gwSvcs
}

	-list regexp
	    List tests, benchmarks, fuzz tests, or examples matching the regular
	    expression. No tests, benchmarks, fuzz tests, or examples will be run.
	    This will only list top-level tests. No subtest or subbenchmarks will be
	    shown.

	-parallel n
	    Allow parallel execution of test functions that call t.Parallel, and
	    fuzz targets that call t.Parallel when running the seed corpus.
