unit testing is that you are not using a simulated environment, but rather the actual implementation of the object in the test. You can simulate data transfer (MOCKWEBSERVER) and database status, then run real code to see how they work.You can run the integration test on the Android instrumentation or JVM device/emulator because the test runs faster on the JVM-the author prefers the JVM.Fail early: Run the integration test in CI and discard the project as early as possible if some of the tests

. Scenario 2: similar to the online problem locating just now, a large number of excellent offline functions cannot be applied to all users, because they are actually hurting the enemy by eight hundred and self-healing by one thousand. How can we recall all problems as much as possible while minimizing user experience loss? A new idea for mobile terminal online problem locating:Build a test plug-in based on the plug-in system to integrate all the offline test capabilities that we find useful,

Use android studio to detect app Memory leakage [reprinted] And androidapp In Android development, various memory leaks are inevitable. If you do not find and handle the vulnerabilities in time, the larger the memory usage, and various strange crash may occur due to memory leaks, the APP may even crash due to insufficient memory. Generally, android Memory leakage detection uses the built-in Monitor Tool of android studio in combination with mat, or a third-party open-source library tool: leakCan

in use.# # # #Android中内存泄漏 The garbage collection mechanism in Android does not prevent memory leaks from causing memory leaks The main reason is that some live objects hold references to other objects that should be recycled, causing the garbage collector to fail to reclaim those objects, which is a memory leak. For example, a system component like activity, which contains many controls and even pictures, is a serious memory leak if it cannot be reclaimed by the garbage collector. For example,

triggers GC when memory is high); The application is being emptied from the background process; Application of inexplicable crashes (i.e. exceeding the heepsize threshold caused by oom). Memory Leak analysis ToolSee these problems. Suddenly found that it seems to be closer to the truth 0.0.To get a clearer picture of the current application's memory usage in real time, we need to implement it through some tools. There are two types of tools that are more useful: Memory Ana

, often use a few buffers, when not in use, should close them in time. The registration object is not logged off. For example, an event that does not log off after registration causes the object's reference to be maintained in the Observer list. The static variables of the class hold large data objects. A static instance of a non-static inner class. Handler temporary memory leaks. If the handler is non-static, it is easy to cause Activity or Service not to be recycled. A memo
