# Testing commands

OBD provides multiple-level commands. You can use the`-h/--help` option to view the help information of sub-commands.

## `obd test mysqltest`

Runs the mysqltest on the specified node of an OcecanBase cluster or ODP. To run the mysqltest, you must install OBClient.

```shell

## `obd test tpch`

This section describes how to run the TPC-H test on the specified node of an OcecanBase cluster or ODP. To run the TPC-H test, you must install OBClient and obtpch.
TPC-H needs to specify an OceanBase target server as the execution target. Before executing the TPC-H test, OBD will transfer the data files required for the test to the specified directory of the specified machine. Please make sure that you have enough disk space on this machine because these files may be relatively large.
Of course, you can prepare the data files on the target machine in advance and then turn off the transfer by using the `-dt/--disable-transfer` option.

```shell
obd test tpch <deploy name> [flags]
```

`deploy name` specifies the name of the deployment configuration file.

| Option | Required | Data type | Default value | Description |
