Hi Alistair, Indeed installing this dependency makes Dr. Geo to work again, and the "could not find module vm-display-X11" error is gone.

Re: [Pharo-users] Performance Testing Tools

by Luke Gorrie

Hi Evan, I am also really interesting in this topic and have been doing a bunch of work on automating statistical benchmarks. I don't have a background in statistics or formal QA but I am learning as I go along :). The tools I'm building are outside Smalltalk. Our full performance test suite takes about a week of machine time to run because tests ~15,000 QEMU VMs with different software versions / configurations / workloads. There is a CI server that runs all those tests, getting pretty fast turnarounds by distributing across a cluster of servers and reusing results from unmodified software branches, and spits out a CSV with one row per test result (giving the benchmark score and the parameters of the test.) Then what to do with that ~15,000 line CSV file? Just now I run Rmarkdown to make a report on the distribution of results and then manually inspect that to check for interesting differences. I lump all of the different configurations in together and treat them as one population at the moment. Here is an example report: https://hydra.snabb.co/build/1604171/download/2/report.html It's a bit primitive but it is getting the job done for release engineering. I'm reasonably confident that new software releases don't break or slow down in obscure configurations. We are building network equipment and performance regressions are generally not acceptable. I'm looking into more clever ways to automatically interpret the results, e.g. fumbling around at https://stats.stackexchange.com/questions/288416/non-parametric-test-if-two… . Could relate to your ambitions somehow?

Need help for SmartTest/CORA

by Benoit Verhaeghe

Hi everyone, I'm working on SmartTest/CORA. It's a plugin that help us with test. It shows us only the test we should run to well tests ours applications. And it will run automatically the tests (or not if you disable this option). It will be great if you can help me by installing it. You only have to execute this command : Metacello new githubUser: 'badetitou' project: 'TestsUsageAnalyser-CORAExtends' commitish: 'master' path: '.' ; baseline: 'TestsUsageAnalyserCORAExtends' ; load . You can also use the plugin with jenkins. Everything are explained here : http://badetitou.github.io/research/smalltalk/2017/07/05/CORA/ Tell me if you are in trouble during the installation Thanks for your help Benoit

Performance Testing Tools

by Evan Donahue

Hi, I've been doing a lot of performance testing lately, and I've found myself wanting to upgrade my methods from ad hoc use of bench and message tally. Is there any kind of framework for like, statistically comparing improvements in performance benchmarks across different versions of code, or anything that generally helps manage the test-tweak-test loop? Just curious what's out there before I go writing something. Too many useful little libraries to keep track of! Evan
