Application testing is disclosed in the present disclosure. An interface structure may be extracted from source code of an application under test (AUT), and the interface structure may be separated into subsections. Then a primary test may be performed for the AUT by using test code to execute the subsections. An assertion strategy in the test code may be evaluated based on a predefined assertion requirement to obtain a first measurement result of the AUT, in which the assertion strategy may be to assert an execution result of the test code executing the subsections.
