Active Testing

This is a software testing type in which the software is tested after it has evolved as a product and not just merely a software. This testing is done by the tester, for testing those properties which count to the smooth running of the software with safety, security, and efficiency and good user performance.

The main difference between active testing and passive testing is that, in active testing, the testing is carried out from the user's point of view, where the main idea is to implement test case to only some definite parts of the software and not in the entire software directly.

Active testing is less a defect-oriented testing, and more a quality oriented testing.

Where passive testing, are the testings which we saw earlier such as the unit testing, regression testing, smoke testing, etc. Both active and passive testing can be functional testing as well as non-functional testing.


The only thing is that in active testing the possibility to troubleshoot the coding and the internal structure of the software is less compared to passive testing. However, if errors, bugs or performance issues are found then a formal report is created through which the sub-testings are carried out later, actively or passively.

System Testing Vs Active Testing

In system testing, we are concerned about the testing the working of all the interconnected modules. That is done after the integration testing and is the last testing to be performed before the software has to be released as a complete product.

On the other hand, Active testing is the one which is somewhat similar to the system testing, but test case is not generated to check all the modules, but to check a part of the software. The main difference is that this testing is carried out only after the system testing has been performed.

Active testing is performed after the software is made available as a product.

System testing is passive testing, which means that the testing is performed so that troubleshooting can be done directly as the software flaw is detected.

On the other hand, active testing, as the name suggests is active, which means that the test is performed to test the system in real time and from the user's point of view with test case which exploits only a part of the software.

What are the different types of active testing methods?

There are two different methods of active testing, one is the functional or black box testing, and the other one is the structural or white box testing.

In the functional testing, correctness is checked and whether the requirements are fulfilled is checked and test cases are designed to do so.

On the other hand, in the structural testing, the structure of the software is tested.

Need For Active Testing

Client's Requirement:

Active testing is performed to check whether the software is meeting all the client's requirements. There are different testing which also ensures the client's requirements of the software.


Active testing is the most important in this category, for the fact that it is carried out after system testing, which means an extra level refinement of the software. In this testing, the tester inputs all the test cases which are relevant to the client's requirements and analyzes the input.

User's Experience:

There are softwares which is not used by a particular group of people but can be used a different group of people ranging from different ages or different culture or demographic regions. Someone who is new to the software must be able to handle the software with easy.


Another important factor is assuring optimum user's experience, which means, that the one who will be using the software should be able to get the best quality or the best response, he could expect from the software.

Real-Time Exploration:

There are softwares which are used for keeping real-time records or data. These kinds of softwares need a kind of testing which can analyze the dynamic behavior of the software. This is important because there are softwares which works on real-time data only, and passive testing cannot be that useful.


There are softwares like the data sensing softwares, objects launching softwares, and softwares used in space, which needs active testing to be analyzed accurately.

Usability Testing:

Generally, usability testing is also a kind of passive testing, that is it can be done when the software is under construction. But usability testing may also be carried out in real time, that is, it is totally carried out from an end user perspective.


This process is a refinement, of usability testing as this is not merely applying test cases on the modules but in the end-product, that is the software.

When software is launched in the market, the market for it is studied beforehand. But no company can actually make an accurate guess about the market demand and trends which will follow the demand. Therefore, when the software is tested actively, many different people and involved in the testing process.


This process can help the developer and tester team to forecast the market potential of the software. And thus after understanding the business trends, necessary steps can be taken.

Understanding the dynamic code behavior:

When performing passive testing, test cases are made for code blocks and the lowest modules possibles, but when the codes are tested individually, their output which may be pipelined to other modules can only be checked in integration testing only.

This makes it much more complicated for the tester to understand, the intermediate result that the code is producing after it transferred into other modules. Also, the dynamic behavior of the codes is never fully known.

This problem is resolved in active testing, as all the parts of the software are tested in running mode.

Features of Active Testing

The features of active testing are as follows:

  • The active testing is performed always before the product is released but always testing when the software is developed as a product, and not just a system tested integration of modules.
  • There are different types of software testing techniques used in active testing. Some techniques are different and some are the same as that of the formal testings which we have learned earlier.
  • Active testing also comprises of compliance testing, and so both business requirements and clients requirement are pre-checked.
  • In this testing, the testers can interact with the software and can validate the crucial components and the demanded features.

Backend Testing

Active Testing Vs Passive Testing

  • In active testing, there can be an interaction between the testing team and the developing team. On the other hand, in the passive testing, there may not be such interaction.
  • In active testing, the testing can be made a real-time process and usage of intellect are used. On the other hand, in the passive testing, the testing cannot be done in real time, and also not much intellect is used, the test cases are the ready-made instruments to carry out the testing.
  • In the active testing, the inputs are from the end-users perspective. On the other hand, in the passive testing, the inputs are more logical and pre-designed.
