Multiple tests with minitest

Question

I have an app with some specs written into minitest. As usual, I start them using rake.

Because some times I got a random results, my specs can pass one time, and fail an other time.

In this case, I can keep the sequence number and replay it later, after fixing. Because I have this kind of tests (with a random result), I generally run rake many time, just to be sure that the app is okay.

I would like to know if there is a nice way to perform multiple rake tests (100 times for example), and stop them if there any failure or any error?
