<p>
Gets the test suite root group. This is a required parameter. For updating or creating the latest qualification
suite, if <code>intendedForQualification</code> is set to true, <code>rootGroup</code> can be an empty string. If
<code>intendedForQualification</code> is false, <code>rootGroup</code> cannot be an empty string. If
<code>rootGroup</code> is empty, and <code>intendedForQualification</code> is set to true, all the qualification
tests are included, and the configuration is default.

For a qualification suite, the minimum length is 0, and the maximum is 2048. For a non-qualification suite, the
minimum length is 1, and the maximum is 2048.
