There are a number of uses for WinRunner. The primary function of this program is to serve as a testing tool  for various applications. Some developers will use WinRunner for load testing purposes. It is excellent when it comes to functioning at the GUI layer, and the user can record and analyze the actions of the user from a number of different programs. 

One of the most powerful aspects of WinRunner is that these tests will be conducted as if  a true user was carrying out various functions.  If you are interested in recording the response time, it may be better to use WinRunner along with LoadRunner. There are a number of reasons why WinRunner is so important in the software development market.

The software industry has become much more competitive in recent years. The companies that are able to develop software quckly with the least number of bugs will have an edge on their competitors. In the past, developers had to spend a great deal of time manually searching for bugs. This combined with the time it took them to debug the software made the development process costly, and it also took longer to complete. Another tedious aspect of software development is testing. The advent of programs such as WinRunner allow developers to automatically test their applications to find bugs or performance problems.

Not only will WinRunner test the application, but it will do so in a manner that is similar to the actual user. This allows the developer to test their software in a highly efficient manner. During the recording phase, WinRunner will capture actions such as key strokes or mouse events. This can be combined with the information that is one the screen. The playback phase will allow the developer to learn more about the application. For example, WinRunner can record a simulation of a user who is using a program such as Internet Explorer. It can even simulate a user that is going to use a specific search engine. It is easy to see why WinRunner has a large number of useful applications for developers.

In some instances, WinRunner will not do anything from the protocol layer. However, it will record user events and offer playback based on these events. The program will act as if a human is actually sitting in front of the computer carrying out various commands. WinRunner cannot function properly unless it has control over the computer. Once it has control over the computer, it can carry out various user functions that have been recently recorded. It is for this reason that a load test cannot be initiated when you want to generate a load. If you want WinRunner to simulate 50 users, you will be required to have 50 computers, and WinRunner must be installed on all of them.

Despite this, WinRunner can be useful for loading when it is used in the proper manner. It has to be used within a load test, because this is the only way it can determine the response time of the user. It must be able to deal with the processing that will be carried out on the hardware. There are a number of scenarios in which using WinRunner is crucially important. If it is used for the right situation, it can have abilities which extend beyond its basic testing functions. Once this happens, the value of the program for your company will be much higher. While WinRunner is a powerful tool, it should also be noted that it does have limitations. Understanding the limits of the program will mean the difference between success and failure, and it must be used for the purpose in which it was designed.

When a developer chooses to use WinRunner, they will find that software development becomes much easier. Not only will developing software become easier, but testing and debugging it will become easier as well. As the software market becomes much more competitive, it is important for companies to use automated tools for testing and checking it. This will allow them to focus on things that are equally important. The developers will also become much more skilled at finding various bugs and errors.
