direct access to Httpservetrequest and HttpServletResponse. 4. Testability:A major problem with testing the STRUTS1 action is that the Execute method exposes the servlet API (which makes the test dependent on the container). A third-party extension--struts testcase--provides a set of Struts1 mock objects (for testing).The Struts 2 action can be tested by initializing, setting properties, calling methods, a

Better search questions, test pruning. Here we use three pruning methods: 1. parity pruning. The question must be exactly at the time point t to reach the destination, and the puppy cannot stay. If the given time t is not the same as the odd distance from the start point to the end point, then it cannot be reached. 2. Accessibility pruning. If K steps are not taken from the start point to the end point, the number of steps on the map is less tha

Note that when the time unit of the return value is milliseconds, the granularity of the value depends on the underlying operating system, and the granularity may be greater. For example, many operating systems measure time in dozens of milliseconds.Return: the
