Dynamic 5 Node configuration integrated into the Automated Test Harness
The ATH now has a 5 node setup that is dynamically created with the use of VMs. The software bundles are then installed and configured, before going on to running the tests. This allows the tests to be run on multiple configurations, without the need to use expensive hardware, freeing up resources for essential development and throughput/stress testing.
This is yet another aid to development, as any code changes would trigger the ATH to be run on the “all in one” configuration and then the “five node” configuration, where any regressions or issues can be picked up immediately. This is a very quick and efficient way of testing multi node configurations of the product. In future there will be a 7 node and a multi data centre configuration, providing the ability to automatically test redundancy and high availability.
The image shows a “five node” test setup and 2 x “all in one” setups. 1 of the all in one systems is being run after a development change, which runs a cut down version of the tests to provide a quick turn-around while developing. The other all in one system runs a full suite of tests that takes much longer to run as all different combinations/permutations are tested; and as a result is run once overnight. The five node also runs the full suite of tests.
