Difference Between QTP and LoadRunner (With Table)

The Quicktest Professional, or QTP, was created solely to stimulate and examine user interactions involving keystrokes and mouse clicks. Because the Quicktest Professional or QTP does the task of testing the GUI, it also performs the task of recording data, specifically which key is pressed or which button is touched. In addition, the actions that were captured are transformed into a script.

The development of LoadRunner‘s testing tool was done solely to simulate several concurrent users or a significant load to stress the system. LoadRunner, the testing tool, is not required to be concerned with the concept of GUI; its primary function is to route and give commands to a proxy based on protocols. It does, however, keep track of all commands it issues. The recorded commands were then translated into a script that may be run on load generator machines to stimulate a large number of users.

Comparison Table Between QTP and LoadRunner

What is QTP?

The abbreviation QTP stands for Quicktest Professional, a tool developed by HP, a hardware company and organisation, for testing purposes. The Quicktest Professional (QTP) was created solely to stimulate and analyse user interactions involving keyboard inputs and mouse clicks.

Because the Quicktest Professional or QTP does the task of testing the GUI, it also performs the task of recording the data, specifically which key is pressed or which button is selected. In addition, the captured activities are transformed into a script.

The Quicktest Professional, or QTP, is mostly dependent on the Windows operating system, and it is used exclusively on that platform. In QTP, the technique of recording the user’s actions on the GUI is used to stimulate the user.

What is LoadRunner?

LoadRunner is another type of tool that is used for testing and is a by-product of the same organisation and firm, HP. This testing instrument, on the other hand, is utilised for a variety of applications. The development of LoadRunner’s testing tool was done solely to simulate several concurrent users or a severe load to stress the system.

LoadRunner, the testing tool, is not required to be concerned with the concept of GUI; its primary function is to route and send commands to a proxy based on protocols. It does, however, keep track of all the commands it issues. The orders were then captured and turned into a script that can be run on load generating machines to stimulate a large number of users.

UNIX can be used to some extent with LoadRunner. These machines are utilised as an alternative to load generators and so provide a greater degree of flexibility to the user. The GUI does not affect LoadRunner. All commands, however, are logged through a proxy.

Main Differences Between QTP and LoadRunner

1. The abbreviation QTP is the short form of Quicktest Professional, which is a tool used for testing purposes by the hardware manufacturer firm and organisation HP. On the other hand, LoadRunner is also a type of tool which is used for testing purposes and is the by-product of the same organisation and company, that is, HP. However, this testing tool is used for different purposes.
2. The development of the Quicktest Professional or QTP was done exclusively for the purpose of stimulation and to examine the user interactions involving keyboard presses and mouse clicks. On the other hand, the development of the testing tool of LoadRunner was done exclusively for stimulation of multiple concurrent users or heavy load to put stress on the system.
3. Due to the reason that the Quicktest Professional or QTP does the work of testing the GUI, it does the work of recording the data that particularly which key is being pressed or which button is being clicked. Furthermore, the actions which were recorded gets converted into a defined script. On the other hand, the testing tool LoadRunner is not mandatorily asked to be concerned with the concept of GUI. Its main work is routing and giving commands based on protocols to a proxy. However, it also records all the commands that it sent. The commands were recorded thereafter were converted to a form of script, which is operated on load generator machines for stimulating many users.
4. The working of the Quicktest Professional or QTP mainly depends upon and is also exclusively used on the operating system of Windows. On the other hand, In the case of LoadRunner, UNIX can be used up to a certain extent. These Machines are used as an alternative to the load generators and thus provide its user with comparatively more flexibility.
5. The stimulation of a user in the case of QTP is done by the process of recording the actions of the user on the GUI. On the other hand, LoadRunner is not at all bothered by GUI. However, all the commands are recorded via a proxy.

Conclusion

QTP stands for Quicktest Professional, a testing tool developed by HP, a hardware manufacturer. The Quicktest Professional, or QTP, was created solely to stimulate and analyse user interactions involving keystrokes and mouse clicks.

Whereas LoadRunner is another form of testing tool that is a by-product of HP. This testing tool, however, has a variety of applications. LoadRunner’s testing tool was created solely to simulate several concurrent users or put a severe strain on the system.

Quicktest Professional, or QTP, is primarily and solely based on the Windows operating system. In the instance of QTP, the stimulation of a user is accomplished by the process of capturing the user’s actions on the GUI. Whereas LoadRunner, the testing tool, does not need to be concerned with the concept of GUI; instead, its primary function is to route and send commands to a proxy-based on protocols.

UNIX can be used to a limited extent with LoadRunner. These machines are utilised as a substitute for load generators, and so offer a greater degree of freedom to the user. GUI makes no difference to LoadRunner. All commands, however, are logged through a proxy.
