CircleCI supports rendering test failures through the use of JUnit files, but it only supports a subset of features.
One such feature is failure test outputs. The spec suggests that stdout and stderr contents be captured and added to the <system-out> and <system-err> elements respectively.
CircleCI instead only reads the data from the <failure message="..."> attribute only.
