The invention discloses a method and system for testing a router. The method comprises the following steps: S300, a tester acquires a testing task stored in advance, and tests at least one to-be-tested router; S400, a server receives a URL access request, judges whether the current testing data is in the normal range, executes step S500 if the current testing data is in the normal range, or executes the step S600; S500, the server outputs that the current testing data is normal, and judges whether the current testing duration satisfies the preset testing duration, executes the step S700 if the current testing duration satisfies the preset testing duration, or returns to step S400; S600, the server outputs that the current testing data is abnormal, judges whether to end the current testing, executes the step S700 if judging to end the current testing, or returning to step S400; and S700, the server controls to end the current testing, and saves the current testing data in a server database. Through the adoption of the method and system disclosed by the invention, the to-be-tested router can be tested, the repeated construction of the testing environment is avoided, the working efficiency is improved, the time and the labor are saved; and the fault problem can be efficiently and rapidly positioned.
