Performance testing objectives
Performance testing is different from functional testing. It is not a right or error test, but a measure of speed and slowness. Before conducting a real performance test, you must first clarify the objectives:
1. Under the specified hardware conditions, the larger the number of concurrent requests, the better the response time. The product manager proposes how many concurrent

type variables?
Volatile has two main functions: 1. Avoid command rearrangement 2. Visibility guarantees. For example, the JVM or JIT will reorder the statements for better performance, but the volatile type variable will not be reordered with other statements even if there are no synchronized blocks. Volatile provides happens-before guarantees that a thread's modifications can be visible to other threads. In some cases, volatile can also provid
In some cases, we need to unit test our own code (the benefit is to reduce the effort and expense of late maintenance), which is some of the most basic module tests. Of course, in the case of unit testing, it is necessary to understand the internal logic implementation of the code we test, so that we can clearly compare the results we expect from the code logic i
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:

. Therefore, the JUnit Unit test framework is used to test the expected results of assertion, common data, organize and run test suites and even include graphics and text testing.
JUnit is so popular and depends on its integration into eclipse. This makes the basics of Java program testing, which can be done in the han
