Focusing on the requirements of dynamically organizing resources in dynamic

open

and distributed grid environment

an infrastructure for constructing grid testenvironment-grid testing engine is proposed

which supports dynamic deployment

update and execution of testing items as well as alarming and auto-handling based on the emergence category of fault. The test pressure of target service is controlled by using tokens and the load balance of distributed testing is realized by token migration. Experiments in ChinaGrid environment show that the impact of the test environment constructed by the grid testing engine on the host system performance is less than 1%

the environment can create test pressure in accord with demands

test resources and service exactly

and reflect the performance trend change.
