También podrías usar `from starlette.testclient import TestClient`.

**FastAPI** proporciona el mismo `starlette.testclient` como `fastapi.testclient` solo por conveniencia para ti, el desarrollador. Pero proviene directamente de Starlette.

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
- Each pool expects each host in this pool has the same number of drives specified as any other host.

	// Set file permission bits.
	mode = fs.FileMode(fi.h.Mode).Perm()

	// Set setuid, setgid and sticky bits.
	if fi.h.Mode&c_ISUID != 0 {
		mode |= fs.ModeSetuid
	}
	if fi.h.Mode&c_ISGID != 0 {
		mode |= fs.ModeSetgid
	}
	if fi.h.Mode&c_ISVTX != 0 {
		mode |= fs.ModeSticky
	}

	// Set file mode bits; clear perm, setuid, setgid, and sticky bits.

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And they would get just one extra correct letter at a time.
