Problems solved by technology

[0005] Testing applications under different network conditions can be difficult
Difficult to predict how an application will behave in the face of a lost network connection or when network conditions are different than expected
Accurately simulating these conditions often involves expensive hardware, running tests multiple times, or manual user intervention

Embodiment Construction

[0017] The network emulation system described herein allows software developers to accurately simulate different network characteristics when testing applications, frameworks, or other software code on single or multiple computers. For example, the present system allows the simulation of a projected network load from thousands of computers using only a small number of computers. The system also provides the ability to "record" real network characteristics and apply those characteristics during testing. For example, a software developer may record different profiles for Wi-Fi networks, Bluetooth networks, 3G cellular networks, and so on. Alternatively or additionally, the software developer can record with high packet loss (such as, 10%), normal packet loss (such as, <1%), high bandwidth, low bandwidth, high latency, low latency, and above An overview of the combined network. The present system provides software developers with the ability to simulate multiple networks (such ...

Abstract

The presen invention provides a network emulation in manual and automated testing tools. A network emulation system is described herein that allows a software developer to accurately simulate different network characteristics while testing an application, framework, or other software code on a single or multiple computers. The system also provides an ability to record a real network's characteristics and apply those characteristics during a test. The network emulation system integrates a network emulation facility into test tools for both manual and automated tests and allows an application, framework, or other software code to be tested while operating under varying networking conditions such as bandwidth, latency, packet reordering and duplication, disconnection, and so forth. Thus, the network emulation system allows a software developer testing software code to quickly and easily determine how the software code will perform in a variety of real-world networking situations without physically setting up each of those situations.

Description

technical field [0001] This application relates to software development technology, especially network simulation technology in software testing. Background technique [0002] Modern software often consists of many components, often developed by large teams of software developers. Gone are the days of procedural programming, where a single developer could write an application that simply executed a single well-defined task from start to finish. Software developers often use libraries, components, frameworks, and other bodies of code written by other developers to generate software code that interacts with other systems and operates in well-connected environments. The chances of making a mistake or misunderstanding about how to use a specific external function or module are higher than ever. [0003] Much of today's software also involves the use of one or more networks. The rise of the Internet and corporate local area networks (LANs) has resulted in most applications inc...
