Copy from https://blog.codecentric.de/en/2011/10/measure-java-performance-sampling-or-instrumentation/In recent discussions, I noticed a confusion on the differences between measuring with sampling andinstrum Entation.I hear about which one should was better than others, but I think it was important to understand what they work. Some Tools even ask to choose between those both directly at startup, like Jprofiler 7 in the picture on the right.But how c

Android testing and instrumentation Android provides a series of powerful testing tools. It extends the industry-standard JUnit testing framework for the android environment. Although you can use JUnit to test the android project, the android tool allows you to perform more complex tests for all aspects of the application, including the unit and framework layers.

In most cases, our web programs not only need to provide specific data to the user, in some cases, we also need to give advanced users or managers to provide data aggregation and analysis of functions such as charts. If we don't want to show a bunch of annoying data, and we want to visualize the data visually with pie or bar charts, we can consider using a chart control to display it. In the following article, we will introduce you to the implementation of the data dashboard program. There wa

weird. In this case, a technology is required. It can use shell to start a group of tests and give results in the form of command lines. This is the so-called instrumentation. 　What is instrumentation? Generally, when developing an android program, you need to write a manifest file with the following structure: ...... In this way, an application is started when the program is started, and t

It is described in the instrumentation JDK as follows: This class provides a means of measurement for programs running on the JVM. Many tools use Instrumenation to modify the method bytecode for data collection purposes. These tools for collecting data through instrumentaion do not change the state and behavior of the program. These good tools include monitoring agents, profilers, coverage analyzers, and event loggers.There are two ways to get an inst

[ADB shell am instrument]Note: The-e option must be placed before the-W option.-W Purpose: Keep the ADB shell open until the test is complete.Example:-W com. Android. Phone. Tests/COM. Android. Phone. Runners. functionaltestrunner-E Purpose: Provides test options in the form of key-value pairs. Android provides multiple key-value pairs. For more information, see the following table.Example:-E Class com. Android. Phone. fincomingcalltests # testrejectcall (value is a fully qualified class name)-R

Brief introductionThe traditional way to measure function uptime without using instrumentation is to log the current system time before the function call and to record the current system time again after the function call is complete (to simplify the description, This article does not consider the timing error caused by the virtual machine process mapping to the local operating system process, and finally returns the difference of two data as the func

Java Instrumentation (reference: http://www.ibm.com/developerworks/cn/java/j-lo-jse61/)Brief introduction:With instrumentation, developers can build application-independent agents to detect and assist programs running on the JVM, and even to replace and modify the definitions of certain classesProblems encountered:Applications running in the Tomcat container, because the main method is executed when the con

In addition to JUnit, Android provides an Instrumentation testing framework. You can use Instrumentation to simulate press, lift, screen click, scroll, and other events to effectively control the Activity for automated testing. Instrumentation is the base class for executing the application instrumentation code. When
