The Older (and discouraged) Serial Test Harness is not yet supported in Mergesium Autotools Integration.
Projects in active development are encouraged to use the new, Parallel Test Harness. This test harness is fully supported today.
It was released in automake v1.11 (May 2009), and promoted as the new default and 'stable' in v1.12v/v1.13 (Dec 2012).
We plan on supporting the serial test harness "eventually", but it's not a high-priority. If your project uses the serial test harness and would like this support to happen sooner, please comment below.
Thank you.
