Overview ¶
Package chrome provides Chrome-specific options for WebDriver.
Index ¶
Constants ¶
const CapabilitiesKey = "goog:chromeOptions"
CapabilitiesKey is the key in the top-level Capabilities map under which ChromeDriver expects the Chrome-specific options to be set.
const DeprecatedCapabilitiesKey = "chromeOptions"
DeprecatedCapabilitiesKey is the legacy version of CapabilitiesKey.
Variables ¶

Functions ¶
func NewExtension ¶
func NewExtension(basePath string) ([]byte, *rsa.PrivateKey, error)
NewExtension creates the payload of a Chrome extension file which is signed using the returned private key.
func NewExtensionWithKey ¶
func NewExtensionWithKey(basePath string, key *rsa.PrivateKey) ([]byte, error)
NewExtensionWithKey creates the payload of a Chrome extension file which is signed by the provided private key.
Types ¶
type Capabilities ¶
type Capabilities struct {
// Path is the file path to the Chrome binary to use.
Path string `json:"binary,omitempty"`
// Args are the command-line arguments to pass to the Chrome binary, in
// addition to the ChromeDriver-supplied ones.
Args []string `json:"args,omitempty"`
// ExcludeSwitches are the command line flags that should be removed from
// the ChromeDriver-supplied default flags. The strings included here should
// not include a preceding '--'.
ExcludeSwitches []string `json:"excludeSwitches,omitempty"`
// Extensions are the list of extensions to install at startup. The
// elements of this list should be the base-64, padded contents of a Chrome
// extension file (.crx). Use the AddExtension method to add a local file.
Extensions []string `json:"extensions,omitempty"`
// LocalState are key/value pairs that are applied to the Local State file
// in the user data folder.
LocalState map[string]interface{} `json:"localState,omitempty"`
// Prefs are the key/value pairs that are applied to the preferences of the
// user profile in use.
Prefs map[string]interface{} `json:"prefs,omitempty"`
// Detatch, if true, will cause the browser to not be killed when
// ChromeDriver quits if the session was not terminated.
Detach *bool `json:"detach,omitempty"`
// DebuggerAddr is the TCP/IP address of a Chrome debugger server to connect
// to.
DebuggerAddr string `json:"debuggerAddress,omitempty"`
// MinidumpPath specifies the directory in which to store Chrome minidumps.
// (This is only available on Linux).
MinidumpPath string `json:"minidumpPath,omitempty"`
// MobileEmulation provides options for mobile emulation.
MobileEmulation *MobileEmulation `json:"mobileEmulation,omitempty"`
// PerfLoggingPrefs specifies options for performance logging.
PerfLoggingPrefs *PerfLoggingPreferences `json:"perfLoggingPrefs,omitempty"`
// WindowTypes is a list of window types that will appear in the list of
// window handles. For access to <webview> elements, include "webview" in
// this list.
WindowTypes []string `json:"windowTypes,omitempty"`
// Android Chrome WebDriver path "com.android.chrome"
AndroidPackage string `json:"androidPackage,omitempty"`
// Use W3C mode, if true.
W3C bool `json:"w3c"`
}
Capabilities defines the Chrome-specific desired capabilities when using ChromeDriver. An instance of this struct can be stored in the Capabilities map with a key of CapabilitiesKey ("goog:chromeOptions"). See https://sites.google.com/a/chromium.org/chromedriver/capabilities
func (*Capabilities) AddExtension ¶
func (c *Capabilities) AddExtension(path string) error
AddExtension adds an extension for the browser to load at startup. The path parameter should be a path to an extension file (which typically has a `.crx` file extension. Note that the contents of the file will be loaded into memory, as required by the protocol.
func (*Capabilities) AddUnpackedExtension ¶
func (c *Capabilities) AddUnpackedExtension(basePath string) error
AddUnpackedExtension creates a packaged Chrome extension with the files below the provided directory path and causes the browser to load that extension at startup.
type DeviceMetrics ¶
type DeviceMetrics struct {
// Width is the width of the screen.
Width uint `json:"width"`
// Height is the height of the screen.
Height uint `json:"height"`
// PixelRatio is the pixel ratio of the screen.
PixelRatio float64 `json:"pixelRatio"`
// Touch indicates whether to emulate touch events. The default is true, if
// unset.
Touch *bool `json:"touch,omitempty"`
}
DeviceMetrics specifies device attributes for emulation.
type MobileEmulation ¶
type MobileEmulation struct {
// DeviceName is the name of the device to emulate, e.g. "Google Nexus 5".
// It should not be set if DeviceMetrics and UserAgent are set.
DeviceName string `json:"deviceName,omitempty"`
// DeviceMetrics provides specifications of an device to emulate. It should
// not be set if DeviceName is set.
DeviceMetrics *DeviceMetrics `json:"deviceMetrics,omitempty"`
// UserAgent specifies the user agent string to send to the remote web
// server.
UserAgent string `json:"userAgent,omitempty"`
}
MobileEmulation provides options for mobile emulation. Only DeviceName or both of DeviceMetrics and UserAgent may be set at once.
type PerfLoggingPreferences ¶
type PerfLoggingPreferences struct {
// EnableNetwork specifies whether of not to collect events from the Network
// domain. The default is true.
EnableNetwork *bool `json:"enableNetwork,omitempty"`
// EnablePage specifies whether or not to collect events from the Page
// domain. The default is true.
EnablePage *bool `json:"enablePage,omitempty"`
// EnableTimeline specifies whether or not to collect events from the
// Timeline domain. When tracing is enabled, Timeline domain is implicitly
// disabled, unless enableTimeline is explicitly set to true.
EnableTimeline *bool `json:"enableTimeline,omitempty"`
// TraceCategories is a comma-separated string of Chrome tracing categories
// for which trace events should be collected. An unspecified or empty string
// disables tracing.
TraceCategories string `json:"traceCategories,omitempty"`
// BufferUsageReportingIntervalMillis is the requested number of milliseconds
// between DevTools trace buffer usage events. For example, if 1000, then
// once per second, DevTools will report how full the trace buffer is. If a
// report indicates the buffer usage is 100%, a warning will be issued.
BufferUsageReportingIntervalMillis uint `json:"bufferUsageReportingInterval,omitempty"`
}
PerfLoggingPreferences specifies configuration options for performance logging.
