Runner Types

By default each test run uses the following underlying hardware specifications:

Runner Type	Platform	Host OS	Architecture	RAM	CPU Cores
default	iOS	MacOS	M1	8 GB	8
cpu1	Android	Ubuntu	x86	12 GB	12

As modern simulators and emulators are becoming more resource intensive, we're is gradually rolling out additional runner types to support more advanced/intensive test scenarios.

Additional runner types are currently in beta as we work to increase capacity.

If your app or test is struggling with the default runner types, you can try the options below. Please note that non-default runner types are charged at the advanced run fee as per our pricing.

Available runners

Runner Type	Platform	Host OS	Architecture	RAM	CPU Cores	Notes
m4	iOS	MacOS	M4	16 GB	10
m1	Android	MacOS	M1	8 GB	8	Very limited capacity. Used for debugging host OS issues on Android.
gpu1	Android	Ubuntu	x86	16 GB	5	Limited capacity. Additional GPU acceleration also provided.

Usage

To use a specialised runner, use the CLI flag --runner-type.

dcd cloud ... --runner-type=<type>

# For example, to use the m4 runner:
dcd cloud ... --runner-type=m4
