From 222319081515f9f6a4c699bd3a406f181a6ddc3b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 29 Jan 2019 06:19:27 -0800 Subject: tests: optionally write results as JUnit-style .xml This will come in handy when publishing the results of Git's test suite during an automated Azure DevOps run. Note: we need to make extra sure that invalid UTF-8 encoding is turned into valid UTF-8 (using the Replacement Character, \uFFFD) because t9902's trace contains such invalid byte sequences, and the task in the Azure Pipeline that uploads the test results would refuse to do anything if it was asked to parse an .xml file with invalid UTF-8 in it.

For comparison: while the Linux build & test is typically done within about 8 minutes, the Windows build & test typically lasts about 80 minutes in Azure Pipelines. To help with that, let's use the Azure Pipeline feature where you can parallelize jobs, make jobs depend on each other, and pass artifacts between them. The tests are distributed using the following heuristic: listing all test scripts ordered by size in descending order (as a cheap way to estimate the overall run time), every Nth script is run (where N is the total number of parallel jobs), starting at the index corresponding to the parallel job. This slicing is performed by a new function that is added to the `test-tool`. To optimize the overall runtime of the entire Pipeline, we need to move the Windows jobs to the beginning (otherwise there would be a very decent chance for the Pipeline to be run only the Windows build, while all the parallel Windows test jobs wait for this single one). We use Azure Pipelines Artifacts for both the minimal Git for Windows SDK as well as the built executables, as deduplication and caching close to the agents makes that really fast. For comparison: while downloading and unpacking the minimal Git for Windows SDK via PowerShell takes only one minute (down from anywhere between 2.5 to 7 when using a shallow clone), uploading it as Pipeline Artifact takes less than 30s and downloading and unpacking less than 20s (sometimes even as little as only twelve seconds).
