st: Test of Normality and Heteroskedasticity

Dear all,
Can any one please tell me what are the STATA commands for testing
normality of errors and heteroskedasticity in a tobit model? Also how
to interpret the results of these tests?
I am trying to use Heckman two step estimator, and therefore, before
the estimation, I would like to test these.
Please help.
Thank you.
Regards,
Danny
