Hi Eliot,

Sorry about the slow reply -

Tests that stress the VM:
- Running the complete test suite
- running update to Squeak trunk tip from Squeak 5.0
- recompiling the entire system
- building a Moose image

Having these run automatically by a CI server would be very nice.

What is the success criteria for the tests? Or is it just that the VM doesn't crash?

Are there scripts anywhere for running these tests and checking the results that could be used for reference?

Once upon a time I included the built-in test suite in my build but it didn't have 100% success rate and I was not sure whether that was a problem and how to make a suitable pass/fail decision.

The success criterion is that they all succeed. By extension this implies that the vm doesn't crash.

Ask on the list of folks like Fabio Niephaus.

Does this mean that the Test Runner should report 100% pass rate? I have never seen that even with the stock image+vm from pharo.org. So I have a bootstrapping problem if I don't have a baseline that passes the CI test.

Just now I ran - randomly - a clean Pharo 5.0 image that I have on my Mac and the result I see is: 9098 run, 7408 passes, 8 skipped, 81 expected failures, 22 failures, 587 errors, 0 unexpected passes. If resolving those 22 failures and 587 errors is a blocker for running a CI then that is quite an obstacle from my perspective.

are other people really seeing 100% pass rates?

Nope, I don't remember ever seeing a 100% pass rate for the entire test
suite. (I don't know how this is handled in CI environments)

Cheers,
Alistair
