ENVIRONMENTS:
    OT_NODE_TYPE    'cli' for CLI simulation, 'ncp' for NCP simulation.
                    'rcp' or 'rcp-cli' for CLI on POSIX platform.
                    'rcp-ncp' for NCP on POSIX platform.
                    The default is 'cli'.
    OT_NATIVE_IP    1 to enable platform UDP and netif on POSIX platform. The default is 0.
    OT_BUILDDIR     The output directory for cmake build. By default the directory is './build'. For example,
                    'OT_BUILDDIR=\${PWD}/my_awesome_build ./script/test clean build'.
    VERBOSE         1 to build or test verbosely. The default is 0.
    VIRTUAL_TIME    1 for virtual time, otherwise real time. The default value is 0 when running expect tests,
                    otherwise default value is 1.
    THREAD_VERSION  1.1 for Thread 1.1 stack, 1.3 for Thread 1.3 stack. The default is 1.3.
    INTER_OP        1 to build 1.1 together. Only works when THREAD_VERSION is 1.3. The default is 0.
    INTER_OP_BBR    1 to build bbr version together. Only works when THREAD_VERSION is 1.3. The default is 1.

COMMANDS:
    clean           Clean built files to prepare for new build.
    build           Build project for running tests. This can be used to rebuild the project for changes.
    cert            Run a single thread-cert test. ENVIRONMENTS should be the same as those given to build or update.
    cert_suite      Run a batch of thread-cert tests and summarize the test results. Only echo logs for failing tests.
    unit            Run all the unit tests. This should be called after simulation is built.
    expect          Run expect tests.
    help            Print this help.
