Function minimalHandler

modules/caddyhttp/reverseproxy/retries_test.go:109–125

minimalHandler returns a Handler with only the fields required by ServeHTTP set directly, bypassing Provision (which requires a full Caddy runtime). RoundRobinSelection is used so that successive iterations of the proxy loop advance through the upstream pool in a predictable order.

(retries int, upstreams ...*Upstream)

// RoundRobinSelection is used so that successive iterations of the proxy loop
// advance through the upstream pool in a predictable order.
func minimalHandler(retries int, upstreams ...*Upstream) *Handler {
	return &Handler{
		logger:    zap.NewNop(),
		Transport: testTransport{&http.Transport{}},
		Upstreams: upstreams,
		LoadBalancing: &LoadBalancing{
			Retries:         retries,
			SelectionPolicy: &RoundRobinSelection{},
			// RetryMatch intentionally nil: dial errors are always retried
			// regardless of RetryMatch or request method.
		},
		// ctx, connections, connectionsMu, events: zero/nil values are safe
		// for the code paths exercised by these tests (TryInterval=0 so
		// ctx.Done() is never consulted; no WebSocket hijacking; no passive
		// health-check event emission).
	}
}

// TestDialErrorBodyRetry verifies that a POST request whose body has NOT been
// pre-buffered via request_buffers can still be retried after a dial error.
