Function NewIsolatedHTTPClient

coderd/coderdtest/coderdtest.go:689–707

NewIsolatedHTTPClient returns a test client with its own transport. Closing idle connections at test cleanup must not close http.DefaultTransport while another parallel test is using it.

(serverURL *url.URL)

// Closing idle connections at test cleanup must not close http.DefaultTransport
// while another parallel test is using it.
func NewIsolatedHTTPClient(serverURL *url.URL) *http.Client {
	transport := &http.Transport{Proxy: http.ProxyFromEnvironment}
	if defaultTransport, ok := http.DefaultTransport.(*http.Transport); ok {
		transport = defaultTransport.Clone()
	}
	if serverURL == nil || serverURL.Scheme != "https" {
		transport.TLSClientConfig = nil
		return &http.Client{Transport: transport}
	}
	if transport.TLSClientConfig == nil {
		transport.TLSClientConfig = &tls.Config{MinVersion: tls.VersionTLS12}
	}
	if transport.TLSClientConfig.MinVersion == 0 {
		transport.TLSClientConfig.MinVersion = tls.VersionTLS12
	}
	//nolint:gosec // The coderdtest server uses test-only TLS certificates.
	transport.TLSClientConfig.InsecureSkipVerify = true

}

// newHTTPClientWithTransportFrom returns a fresh client that shares the base
// transport without sharing mutable per-client state like CheckRedirect.
