View Service Quality Testing according to INSPIRE Implementing Rules
In collaboration with COSMC it has been prepared new tests of WMS services which focus on two main aspects: a) Monitoring the availability of WMS related with records of errors, and continuous monitoring of response quickness and other performance parameters. Test period was two months. For each layer are specified scale and location in the map and other parameters in requirements generated by the client. The evaluation utilizes average, maximum and minimum execution requirement times, the overall performance of the tested application, the error rate of approaches and the average bandwidth in the access. b) Stress tests, which were carried out during the holidays to simulate the high server performance and its behavior under such conditions. Tests help determine the physical limits of system performance.The aim of both versions of tests is to evaluate the availability, performance characteristics and stress behavior of this service from the client's perspective. Results of the client-side testing are evaluated together with analysis of server’s logs. Results of performance and stress tests confirm that management capacity and performance criteria of the INSPIRE directive. Internal server error is at a very low level, client-side error rates are continually recorded from 3 to 5%. Ill. 7, bibl. 14, tabl. 2 (in English; abstracts in English and Lithuanian).
