Method for realizing product automatic test by test environment composed of test set

The present invention resolves testing environment into grade assignment plurality of test suites with tree structure according to required testing environment and testing logic; then selecting final stage located anyone test suites, according to said first stage, second stage to the last stage and self in turn establishing corresponded testing environment; then executing established testing environment configured testing logic, recovering testing environment established according to current selected test suites; according to same mode to each test suites located branching end for executing corresponded testing logic, to each test suites, ensuring only executing once step of establishing testing environment and recovering established testing environment.
