 As you see, we define variables in `config` block. Also, we can set `base_url` in `config` block, thereby we can specify relative path in each API request url. Besides, we can also set common fields in `config` `request`, such as `device_sn` in headers.

 Function invoke is supported in `YAML/JSON` format testcases, such as `gen_random_string` and `get_sign` above. This mechanism relies on the `debugtak.py` hot plugin, with which we can define functions in `debugtak.py` file, and then functions can be auto discovered and invoked in runtime.
