Trade Federation Global Configuration
Stay organized with collections
Save and categorize content based on your preferences.
The Trade Federation (TF) Global Configuration is a file that is loaded once
upon TF initialization. This configuration file is used to define the
environment for that instance of TF.
Load the Global Configuration file
The TF Global Configuration file is an XML file and can be specified by setting
the local environment variable TF_GLOBAL_CONFIG. If TF_GLOBAL_CONFIG is
not specified, TF will try to locate a file named tf_global_config.xml in its
current working path. If that fails, TF will load the default Global
Configuration file. For example, you can launch TF with your custom global
configuration via the following command:
TF_GLOBAL_CONFIG=/path/to/my/custom/good_tf_global_conf.xml tradefed.sh
Example Global Configuration file
<configuration description="Example Global Config">
<device_manager class="com.android.tradefed.device.DeviceManager">
<option name="max-null-devices" value="10" />
</device_manager>
</configuration>
The example above sets the number of "null-device" placeholders to 10 instead of
the default value define in the DeviceManager.
