usage: hrun run [-h] optional arguments: -h, --help show this help message and exit

这个命令的输出是提示信息，说明 `run` 命令需要传入一些参数。下面是 `run` 命令的使用说明：

usage: hrun run [-h] [-k CASELIST] [-V] [-H HEADERS] [-s VARIABLES] [-o REPORT] [-n PROCESS_NUMBER] [-d DELAY] [-e EXPORT] [-q] testcase_file

positional arguments:
  testcase_file         specify a testcase file

optional arguments:
  -h, --help            show this help message and exit
  -k CASELIST, --cases CASELIST
                        specify case name, support regex match
  -V, --verify          enable SSL certificate verification
  -H HEADERS, --headers HEADERS
                        specify request headers, overwrite the headers in testcase
  -s VARIABLES, --variables VARIABLES
                        specify variables file, overwrite the variables in testcase
  -o REPORT, --report REPORT
                        specify report file, generate html report and api doc
  -n PROCESS_NUMBER, --processes PROCESS_NUMBER
                        specify process number to run testcase in parallel
  -d DELAY, --delay DELAY
                        specify delay seconds between two testcases
  -e EXPORT, --export EXPORT
                        export testcases to CSV/JSON/YAML format files
  -q, --quite           print log with error level

你可以根据实际需要在命令中添加相应的参数来执行测试用例。例如，执行 `hrun run testsuites/example_testcase.yml` 命令来运行示例测试用例。
