# Android Compatibility Test Suite - Root extension (CTS-Root) This is an extension the main CTS test suite, for general compatibility tests that require root privileges or a debuggable device. Note that the name of this suite in the build system is CTS_ROOT (with an underscore), so this is built with `m cts_root` and tests must be tagged with `cts_root` in their test_suites to be included. However in tradefed the name is cts-root (with a hyphen), so use `cts-root-tradefed` to run it, and `run cts-root` to run the default cts-root plan.
