Public methods

getTestShard

public IRemoteTest getTestShard (int shardCount, 
                int shardIndex)

Returns a IRemoteTest for a single shard. This must be deterministic and always return the same IRemoteTest for the same input.

Parameters
shardCount int: the number of total shards
shardIndex int: the index of a test shard to return. The value is in range [0, shardCount).
Returns
IRemoteTest a IRemoteTest

setDeviceInfos

public void setDeviceInfos (Map<ITestDevice, IBuildInfo> deviceInfos)

Parameters
deviceInfos Map

Protected methods

preRun

protected void preRun ()

Setup before running the test.

The method tokenizes the command line arguments specified by --tf-command-line, and appends the arguments to the subprocess of TF run. It also passes in the serial of the test device through --serial option, to force the subprocess to use the device selected by the parent TF process.
