# Benchmark datasets for testing multiple regression or multivariate regression model?

I have a question as a newbie. I'm working on a tool using regression analysis( linear, multiple, multivariate) to derive a regression model. To verify the correctness of the tool, I'm trying to find a benchmark, or a benchmark dataset to test the tool. Any idea or comments are all welcomed. Thanks in advance.

Generate some random data yourself in whatever language you're using, that follow the assumptions of your model, e.g., for linear regression generate $X$, then $\beta$, then do $y = X\beta + \epsilon$ where $\epsilon$ is normally distributed with mean zero and sd of say 1. See if you can recover the correct $\beta$ when varying the error stdev. Compare with the multitude of established tools for doing regression.
