2018-08-17 Thread Travis Scrimshaw
Thank you for working towards giving us extra tools to help us prevent regressions. It is definitely something we can put to good use. However, the total time it takes to test a file is somewhat of a bad metric as adding lots of (sometimes relatively computationally intensive) tests to a file w
