Functions

func APKPath 

func APKPath(value string) string

APKPath returns the absolute path to a helper APK.

func AndroidDataDir 

func AndroidDataDir(ctx context.Context, user string) (string, error)

AndroidDataDir returns the ChromeOS path from which /data/ can be accessed (/home/root/${USER_HASH}/android-data).

func AppendToArcvmDevConf 

func AppendToArcvmDevConf(ctx context.Context, text string) error

AppendToArcvmDevConf appends the string to the arcvm_dev.conf on ARCVM devices. Useful for modifying crosvm flags. Backs up the original content to arcvm_dev.conf.tast-backup which should later be restored with RestoreArcvmDevConf. Care should be taken to only write or append to the config once during a test run (either from the test itself or from the fixture) to avoid overwriting the backup config file.

func BlockOutbound 

func BlockOutbound(ctx context.Context) error

BlockOutbound blocks all outbound traffic from ARC.

func Booted 

func Booted() testing.Precondition

Booted returns a precondition that ARC Container has already booted when a test is run.

When adding a test, the testing.Test.Pre field may be set to the value returned by this function. Later, in the main test function, the value returned by testing.State.PreValue may be converted to a PreData containing already-initialized chrome.Chrome and ARC objects: 

func DoSomething(ctx context.Context, s *testing.State) {
	d := s.PreValue().(arc.PreData)
	conn, err := d.Chrome.NewConn(ctx, "http://www.example.org/")
	...
	cmd := d.ARC.Command(ctx, "dumpsys", "window", "displays")
	...
}

When using this precondition, tests cannot call New or chrome.New. The Chrome and ARC instances are also shared and cannot be closed by tests.

func BootstrapCommand 

func BootstrapCommand(ctx context.Context, name string, arg ...string) *testexec.Cmd

BootstrapCommand runs a command with android-sh.

It is very rare you want to call this function from your test; call Command instead. A valid use case would to run commands in the Android mini container, to set up adb, etc.

This function should be called only after WaitAndroidInit returns successfully. Please keep in mind that command execution environment of android-sh is not exactly the same as the actual Android container.

func CheckNoDex2Oat 

func CheckNoDex2Oat(outDir string) error

CheckNoDex2Oat verifies whether ARC is pre-optimized and no dex2oat was previously running in the background.

func ClickAddAccountInSettings 

func ClickAddAccountInSettings(ctx context.Context, arcDevice *androidui.Device, tconn *chrome.TestConn) error

ClickAddAccountInSettings clicks Add account > Google in ARC Settings. Settings window should be already open.

func DisableSyncFlags 

func DisableSyncFlags() []string

DisableSyncFlags is the default flags for disabling ARC content sync and background activities when using GAIA accounts. --arc-disable-app-sync - prevents syncing installed apps from the previous sessions. --arc-disable-play-auto-install - disables PAI flow that downloads and installs apps in the background. --arc-play-store-auto-update=off - prevents Play Store and GMS Core from third party app update and prevents self-updates and downloadable content. --arc-disable-locale-sync - don’t propagate locale sync for the account that might cause reconfiguration updates. --arc-disable-media-store-maintenance - disables GMS scheduling of media store periodic indexing and corpora maintenance tasks.

func InitPID 

func InitPID() (int32, error)

InitPID returns the PID (outside the guest) of the ARC init process. It returns an error in case process is not found.

func Lock 

func Lock()

Lock sets a flag that makes New and Close fail unconditionally. Preconditions and fixtures should call this function on setup to prevent tests from invalidating an ARC object by a mistake.

func MyFilesVolumeID 

func MyFilesVolumeID(ctx context.Context, a *ARC) (string, error)

MyFilesVolumeID returns the volume ID of the MyFiles volume. It waits for the volume to be mounted if it is not mounted yet.

func NetworkInterfaceNames(ctx context.Context) ([]string, error)

NetworkInterfaceNames filters Android interfaces and returns ARC related network interfaces.

func NewArcBootedFixture 

func NewArcBootedFixture(fOpts chrome.OptionsCallback) testing.FixtureImpl

func SDCardVolumeID 

func SDCardVolumeID(ctx context.Context, a *ARC) (string, error)

SDCardVolumeID returns the volume ID of the sdcard volume (/storage/emulated/0). Although the volume ID itself is a constant, the function waits for the volume to be mounted if it is not mounted yet, so that the ID is guaranteed to be valid and usable inside ARC.

func SDKVersion 

func SDKVersion() (int, error)

SDKVersion returns the ARC's Android SDK version for the current ARC image installed into the DUT.

func Supported 

func Supported() bool

It is very rare you want to call this function from your test; to wait for the Android system to start and become ready, call New instead. A valid use case is when you want to interact with Android mini container.

It is fine to call BootstrapCommand after this function successfully returns.

func WaitForARCMyFilesVolumeMount

WaitForARCMyFilesVolumeMount waits for the MyFiles volume to be mounted inside ARC.

func WaitForARCMyFilesVolumeMountIfARCVMEnabled

func WaitForARCMyFilesVolumeUnmount(ctx context.Context, a *ARC) error

WaitForARCMyFilesVolumeUnmount waits for the MyFiles volume to be unmounted inside ARC.

Backs up original content to arcvm_dev.conf.tast-backup which should later be restored with RestoreArcvmDevConf. Care should be taken to only write or append to the config once during a test run (either from the test itself or from the fixture) to avoid overwriting the backup config file.
