chromedriver中的浏览器选项

There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2016-10-20.

ConditionExplanation
--/prefetch:1[1]  /prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn\'t be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. 
--/prefetch:2[1]  No description 
--/prefetch:3[1]  No description 
--/prefetch:4[1]  No description 
--/prefetch:5[1]  /prefetch:# arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on kPrefetchArgument* in content_switches.cc. 
--/prefetch:6[1]  No description 
--/prefetch:8[1]  /prefetch:# argument shared by all process types that don\'t have their own. It is likely that the prefetcher won\'t work for these process types as it won\'t be able to observe consistent file reads across launches. However, having a valid prefetch argument for these process types is required to prevent them from interfering with the prefetch profile of the browser process. 
--0  Value of the --profiler-timing flag that will disable timing information for chrome://profiler. 
--?  No description 
--accept-resource-provider  Flag indicating that a resource provider must be set up to provide cast receiver with resources. Apps cannot start until provided resources. This flag implies --alsa-check-close-timeout=0. 
--adaboost  No description 
--aec-refined-adaptive-filter  Enables a new tuning of the WebRTC Acoustic Echo Canceler (AEC). The new tuning aims at resolving two issues with the AEC: https://bugs.chromium.org/p/webrtc/issues/detail?id=5777 https://bugs.chromium.org/p/webrtc/issues/detail?id=5778 TODO(hlundin): Remove this switch when experimentation is over; crbug.com/603821. 
--agc-startup-min-volume  Override the default minimum starting volume of the Automatic Gain Control algorithm in WebRTC used with audio tracks from getUserMedia. The valid range is 12-255. Values outside that range will be clamped to the lowest or highest valid value inside WebRTC. TODO(tommi): Remove this switch when crbug.com/555577 is fixed. 
--aggressive  No description 
--aggressive-cache-discard  No description 
--aggressive-tab-discard  No description 
--allow-cross-origin-auth-prompt  Allows third-party content included on a page to prompt for a HTTP basic auth username/password pair. 
--allow-data-roaming-by-default  If this flag is set, enable data roaming in the cellular network by default upon system start if it\'s an unmanaged device. This flag is used by Rialto device to obtain device policy during OOBE since the Rialto device has no display and and only connects over cell. 
--allow-external-pages  Allow access to external pages during layout tests. 
--allow-failed-policy-fetch-for-test  If this flag is passed, failed policy fetches will not cause profile initialization to fail. This is useful for tests because it means that tests don\'t have to mock out the policy infrastructure. 
--allow-file-access  On ChromeOS, file:// access is disabled except for certain whitelisted directories. This switch re-enables file:// for testing. 
--allow-file-access-from-files  By default, file:// URIs cannot read other file:// URIs. This is an override for developers who need the old behavior for testing. 
--allow-hidden-media-playback  Allows media playback for hidden WebContents 
--allow-http-background-page  Allows non-https URL for background_page for hosted apps. 
--allow-http-screen-capture  Allow non-secure origins to use the screen capture API and the desktopCapture extension API. 
--allow-insecure-localhost  Enables TLS/SSL errors on localhost to be ignored (no interstitial, no blocking of requests). 
--allow-legacy-extension-manifests  Allows the browser to load extensions that lack a modern manifest when that would otherwise be forbidden. 
--allow-loopback-in-peer-connection  Allows loopback interface to be added in network list for peer connection.

--allow-nacl-socket-api[2]  Specifies comma-separated list of extension ids or hosts to grant access to TCP/UDP socket APIs. 
--allow-no-sandbox-job  Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in RemoteApps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard. Also we lose the chance to kill some processes until the outer job that owns them finishes. 
--allow-non-localhost  No description 
--allow-outdated-plugins  Don\'t block outdated plugins. 
--allow-ra-in-dev-mode  Allows remote attestation (RA) in dev mode for testing purpose. Usually RA is disabled in dev mode because it will always fail. However, there are cases in testing where we do want to go through the permission flow even in dev mode. This can be enabled by this flag. 
--allow-running-insecure-content  By default, an https page cannot run JavaScript, CSS or plugins from http URLs. This provides an override to get the old insecure behavior. 
--allow-sandbox-debugging  Allows debugging of sandboxed processes (see zygote_main_linux.cc). 
--allow-silent-push  Allows Web Push notifications that do not show a notification. 
--alsa-check-close-timeout  Time in ms to wait before closing the PCM handle when no more mixer inputs remain. Assumed to be 0 if --accept-resource-provider is present.

--alsa-output-device[3]  The Alsa device to use when opening an audio stream. 
--alsa-output-period-size  Size of the ALSA output period in frames. The period of an ALSA output device determines how many frames elapse between hardware interrupts. 
--alsa-output-start-threshold  How many frames need to be in the output buffer before output starts. 
--also-emit-success-logs  Also emit full event trace logs for successful tests.

This is useful for finding issues in the metrics code during UI and performance tests. 
--mhtml-generator-option  Sets options for MHTML generator to skip no-store resources: "skip-nostore-main" - fails to save a page if main frame is \'no-store\' "skip-nostore-all" - also skips no-store subresources.

--nacl-debug-mask  Uses NaCl manifest URL to choose whether NaCl program will be debugged by debug stub. Switch value format: [!]pattern1,pattern2,...,patternN. Each pattern uses the same syntax as patterns in Chrome extension manifest. The only difference is that * scheme matches all schemes instead of matching only http and https. If the value doesn\'t start with !, a program will be debugged if manifest URL matches any pattern. If the value starts with !, a program will be debugged if manifest URL does not match any pattern.
--nacl-gdb  Native Client GDB debugger that will be launched automatically when needed. 
--nacl-gdb-script  GDB script to pass to the nacl-gdb debugger at startup.

--no-wifi  Disable features that require WiFi management. 
--no-zygote  Disables the use of a zygote process for forking child processes. Instead, child processes will be forked and exec\'d directly. Note that --no-sandbox should also be used together with this flag because the sandbox needs the zygote to work. 
--noerrdialogs  Suppresses all error dialogs when present. 
--non-material  Classic, non-material, mode for the |kTopChromeMD| switch. 
--non-secure  No description 
--none[10]  No description

--try-supported-channel-layouts[1]  Instead of always using the hardware channel layout, check if a driver supports the source channel layout. Avoids outputting empty channels and permits drivers to enable stereo to multichannel expansion. Kept behind a flag since some drivers lie about supported layouts and hang when used. See http://crbug.com/259165 for more details.

--use-file-for-fake-audio-capture  Play a .wav file as the microphone. Note that for WebRTC calls we\'ll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). The input file is converted to suit Chrome\'s audio buses if necessary, so most sane .wav files should work. You can pass either <path> to play the file looping or <path>%noloop to stop after playing the file to completion. 
--use-file-for-fake-video-capture  Use an .y4m file to play as the webcam. See the comments in media/capture/video/file_video_capture_device.h for more details.

--virtual-time-budget  If set the system waits the specified number of virtual milliseconds before deeming the page to be ready. For determinism virtual time does not advance while there are pending network fetches (i.e no timers will fire). Once all network fetches have completed, timers fire and if the system runs out of virtual time is fastforwarded so the next timer fires immediatley, until the specified virtual time budget is exhausted.
