注意事项：Chrome添加ignoreDefaultArgs: ["--enable-automation"]无效，请自行测试
const optionsLaunch = {
headless: false,
devtools: false,
defaultViewport: {
width: 1200,
height: 900
},
slowMo: 250,
timeout: 0,
// product: "chrome",
ignoreHTTPSErrors: true,
ignoreDefaultArgs: ["--enable-automation"],
// channel: "chrome",
// executablePath: "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
};
问题：异常之后如何处理？
解决方案：我这边个人一般是当遇见异常中，退出当前浏览器，重新创建一个新的即可。
Condition Explanation
--/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 arguments are used by the Windows prefetcher to disambiguate different execution modes (i.e. process types) of the same executable image so that different types of processes don't trample each others' prefetch behavior. Legal values are integers in the range [1, 8]. We reserve 8 to mean "whatever", and this will ultimately lead to processes with /prefetch:8 having inconsistent behavior thus disabling prefetch in practice. TODO(rockot): Make it possible for embedders to override this argument on a per-service basis. ↪
--10000 ⊗ No description ↪
--100000 ⊗ No description ↪

--50000 ⊗ No description ↪
--500000 ⊗ No description ↪
--5000000 ⊗ No description ↪
--? ⊗ 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 ↪
--add-gpu-appcontainer-caps[1] ⊗ Add additional capabilities to the AppContainer sandbox on the GPU process. ↪
--add-xr-appcontainer-caps[1] ⊗ Add additional capabilities to the AppContainer sandbox used for XR compositing. ↪
--additional-trust-token-key-commitments ⊗ Manually sets additional Trust Tokens key commitments in the network service to the given value, which should be a JSON dictionary satisfying the requirements of TrustTokenKeyCommitmentParser::ParseMultipleIssuers. These keys are available in addition to keys provided by the most recent call to TrustTokenKeyCommitments::Set. For issuers with keys provided through both the command line and TrustTokenKeyCommitments::Set, the keys provided through the command line take precedence. This is because someone testing manually might want to pass additional keys via the command line to a real Chrome release with the component updater enabled, and it would be surprising if the manually-passed keys were overwritten some time after startup when the component updater runs. ↪
--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. ↪

--allow-external-pages ⊗ Allow access to external pages during web 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-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-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-outdated-plugins ⊗ Don't block outdated plugins. ↪
--allow-popups-during-page-unload ⊗ Allow a page to show popups during its unloading. TODO(https://crbug.com/937569): Remove this in Chrome 88. ↪
--allow-pre-commit-input ⊗ Allows processing of input before a frame has been committed. TODO(schenney): crbug.com/987626. Used by headless. Look for a way not involving a command line switch. ↪
--allow-profiles-outside-user-dir ⊗ Allows profiles to be created outside of the user data dir. TODO(https://crbug.com/1060366): Various places in Chrome assume that all profiles are within the user data dir. Some tests need to violate that assumption. The switch should be removed after this workaround is no longer needed. ↪
--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 ⊗ No description ↪
--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-enable-upsampling ⊗ Flag that enables resampling audio with sample rate below 32kHz up to 48kHz. Should be set to true for internal audio products. ↪

--arc-disable-gms-core-cache ⊗ Used in autotest to disable GMS-core caches which is on by default. ↪
--arc-disable-locale-sync ⊗ Flag that disables ARC locale sync with Android container. Used in autotest to prevent conditions when certain apps, including Play Store may get restarted. Restarting Play Store may cause random test failures. Enabling this flag would also forces ARC container to use 'en-US' as a locale and 'en-US,en' as preferred languages. ↪
--arc-disable-play-auto-install ⊗ Flag that disables ARC Play Auto Install flow that installs set of predefined apps silently. Used in autotests to resolve racy conditions. ↪

--arc-scale ⊗ Set the scale for ARC apps. This is in DPI. e.g. 280 DPI is ~ 1.75 device scale factor. See https://source.android.com/compatibility/android-cdd#3_7_runtime_compatibility for list of supported DPI values. ↪
--arc-start-mode ⊗ Defines how to start ARC. This can take one of the following values: - always-start automatically start with Play Store UI support. - always-start-with-no-play-store automatically start without Play Store UI. If it is not set, then ARC is started in default mode. ↪

For instance, --auto-select-desktop-capture-source="Entire screen" will automatically select sharing the entire screen in English locales. The switch value only needs to be substring of the capture source name, i.e. "display" would match "Built-in display" and "External display", whichever comes first. ↪

--browser-startup-dialog ⊗ Causes the browser process to display a dialog on launch. ↪
--browser-subprocess-path ⊗ Path to the exe to run for the renderer and plugin subprocesses. ↪

--cleanup-id ⊗ Identifier used to group all reports generated during the same run of the cleaner, including runs before and after a reboot. The id is generated by the first cleaner process for a run, and propagated to spawned or scheduled cleaner processes. A new id will be generated in the first process for a subsequent cleanup, so cleanups from the same user cannot be tracked over time. ↪
--clear-key-cdm-path-for-testing ⊗ Specifies the path to the Clear Key CDM for testing, which is necessary to support External Clear Key key system when library CDM is enabled. Note that External Clear Key key system support is also controlled by feature kExternalClearKeyForTesting. ↪
