Types

type Config

type Config struct {
	// Server URL for the chrome developer protocol to be used for tests
	// can be overridden by the "cdp_server_url" in the transaction config inputs
	ServerURL string `json:"server_url" yaml:"server_url"`

	// Perform DNS discovery with the server hostname
	// The web driver needs to maintain the same cdp server across multiple http
	// requests. This needed when using multiple cdp servers that are load balanced
	// by DNS round robin, like a kubernetes headless service.
	DNSDiscovery bool `json:"dns_discovery" yaml:"dns_discovery"`

	// Path to chrome binary
	BinaryPath string `json:"binary_path" yaml:"binary_path"`

	// Arguments for launching chrome
	BinaryArgs []string `json:"binary_args" yaml:"binary_args"`

	// Interval for recycling chrome processes
	RecycleInterval time.Duration
	// contains filtered or unexported fields
}
