// The RemoteTestServer runs an external Python-based test server in another
// machine that is different from the machine that executes the tests. It is
// necessary because it's not always possible to run the test server on the same
// machine (it doesn't run on Android and Fuchsia because it's written in
// Python).
// The actual test server is executed on the host machine, while the unit tests
// themselves continue running on the device. To control the test server on the
// host machine, a second HTTP server is started, the spawner server, which
// controls the life cycle of remote test servers. Calls to start/kill the
// SpawnedTestServer are then redirected to the spawner server via
// this spawner communicator. The spawner is implemented in
// build/util/lib/common/ .
// Currently the following two commands are supported by spawner.
// (1) Start Python test server, format is:
// Path: "/start".
// Method: "POST".
// Data to server: all arguments needed to launch the Python test server, in
// JSON format.
// Data from server: a JSON dict includes the following two field if success,
// "port": the port the Python test server actually listen on that.
// "message": must be "started".
// (2) Kill Python test server, format is:
// Path: "/kill".
// Method: "GET".
// Data to server: port=<server_port>.
// Data from server: String "killed" returned if success.
// The internal I/O thread is required by net stack to perform net I/O.
// The Start/StopServer methods block the caller thread until result is
// fetched from spawner server or timed-out.
