How to Perform a System Test on Software

Integrated hardware testing process with software system to ensure that the system meets its stated requirements.


Verification: Verification verification and the provision of specific proof that certain requirements have been met.

If the application has three modules A, B, and C, then the test performed by combining modules A&B or module B & C or module A&C is known as Integration testing.


Combining all three modules and testing it as a complete program is called Program Testing.

So ... do you really think it would take that much time to test, what you call System Testing, even after spending a lot of effort on Integration Testing?


The client we just talked to about the project was unsure of the rating we gave for each test attempt.


I had to give an example:

I would like to elaborate on our efforts and the importance of system testing for example.


Example Test System


A car manufacturer does not produce a car like the rest of the car. Each part of the car is manufactured separately, such as seats, steering wheel, mirror, recess, cable, engine, car frame, wheels etc.


After each item is manufactured, it is tested independently for performance and this is called unit testing.


Now, when each component is combined with another component, that composite component is tested to see if the compound did not produce any side effects in the performance of each component and whether both components work together as expected and this is called merging testing.


Once all the parts are connected and the car is ready, it is actually not ready.

The whole car needs to be considered for different requirements such as if the car is not properly driven, breaks, gears, etc. working properly, the car does not show fatigue after driving 2500 km continuously, the color of the car is generally accepted and loved, the car can be driven on any kind of smooth and bad roads. , smooth and straightforward, etc. and all of this testing effort is called System Testing and is not integrated with integration testing.


The model worked as expected and the client was convinced of the required system testing efforts.


How It is done when the Consolidation Test is completed ?


Mainly check the black box type. This test checks the performance of the system from a user's point of view, with the help of a specified document. It does not require any internal knowledge of programs such as format or coding.


Contains active and inactive components of the program / product.


Focus factors:


It focuses mainly on the following:


  • External external connectors
  • Multiprograms and complex functionality
  • Security
  • Restoration
  • Performance
  • Smooth user communication with the system
  • Installation
  • Documents
  • Usability
  • Load / Pressure


Why Test System?


1) It is very important to complete the full test cycle and ST is the stage in which it is performed.


 2) The ST is done in a similar environment to the production site and that is why participants can get a good idea of ​​the user’s reaction.


 3) It helps to minimize post-problem solving and support calls.


 4) In this section of STLC Design Design Applications and Business Needs, both are explored.


This testing is very important and plays an important role in delivering quality product to the customer.


Let us see the significance of this test by using the examples below that cover our daily activities:


  1. What if online activity fails after verification?


  1. What if an item placed on an online shopping cart does not allow you to place an order?


  1. What if in a Gmail account creating a new label gives an error by clicking the create tab?


  1. What if the system crashes when the load is lifted from the system?


  1. What if the system crashes and can't restore data as it wants?


  1. What if installing software on a system takes longer than expected and ultimately results in error?


  1. What if the website response time is significantly higher than expected after the upgrade?


  1. What if the website is so slow that the user can book his travel ticket?


Above are a few examples to show how the System Test will affect if not done correctly.


All of the above examples are simply the result of a systemic test that was not performed or performed correctly. All integrated modules should be tested to ensure that the product is compliant.


  • Is This Checking The White Box Or The Black Box?

System testing can be considered as a black box test.


Black box Test method does not require internal code information while white box method requires internal code information.


While operating system is operational and non-functional, security, functionality and many other types of testing are covered and tested using the black box method where input is supplied to the system and output is guaranteed. Internal system information is not required.


How to Perform a System Test?


It is actually part of a software test and the Test Plan should always contain a specific space for this test.


To evaluate the whole system, needs and expectations should be clear and the tester needs to understand the real-time application of the application.

Also, many third-party tools, OS versions, tastes and OS properties can affect system performance, performance, security, recovery or installation.


Therefore, when testing the system a clear picture of how the app will be used and what kind of problems you may face in real time can help. In addition, a needs document is as important as understanding the application.


A clear and updated requirements document can save the examiner from a number of misunderstandings, guesses, and questions.


In short, a straightforward and explicit requirement document with the latest updates and understanding of real-time application of the application can make ST more productive.


These tests are performed in a systematic and systematic manner.


Given below are the various steps involved in conducting this assessment:


  • The first step is to create a Test Plan.
  • Create Test System Conditions and Test Documents.


  • Prepare the test data required for this test.


  • Use system and script test conditions.
  • Report bedbugs. Check for bugs once they are fixed.


  • Reversal test to confirm the effect of the change in code.


  • Repeat the test cycle until the system is ready for shipment.
  • Exit the test group.


What Should You Check?


The points listed below are included in this review:


  • End to End testing which includes ensuring interaction between all components and external peripherals to ensure that the system is working properly in any of the conditions present in this test.
  • It ensures that the input provided to the system provides the expected result.
  • It ensures that all functional and non-functional needs are assessed and whether they are working as expected or not.
  • Ad-hoc testing and testing can be done on this test after the completion of the written test. Experimental testing and ad-hoc testing help to identify distractions that are not found in written tests as it gives freedom to testers to test as their desire is based on their experience and understanding.




There are a few benefits:


This test includes system testing conditions.


  • This test is performed in the same location as the Product area which helps to understand the user's point of view and prevents possible problems when the system is live.


  • If this test is done in a systematic and appropriate way, it can help to reduce post-production problems.


  • This test assesses both application design and business needs.


  • Login / Exit Terms


Let's take a closer look at the Login / Exit Terms of the System Test.


Login Terms:


The system should have met the test exit conditions. Consolidation means that all test cases should have been performed and there should be no critical or P1 priority, P2 error in the open state.


  • The Test Plan for this test must be approved and signed.


  • Cases / conditions for testing should be ready for implementation.


  • Test scripts should be ready for implementation.


  • All non-functional requirements must be met and cases of similar testing should be made.


  • The test site should be ready.



Exit Term:


  • All test cases must be released.


  • There are no significant mistakes or Important or security related issues that should be in the open.


  • If any significant intermediate or low-key interruptions are in the open, they should be used to the customer's preference.


  • Exit report must be submitted.


System Check System


A Document Review is a document used to describe the purpose, purpose, and scope of a product to be developed. What should be tested and what should not be tested, testing strategies, tools to be used, the required location and all other details are written down for further testing.


The Test Plan helps to continue testing in a more systematic and strategic way and helps to avoid any risks or problems while the test is being performed.

The System Check Plan includes the following points:


Purpose & Objective explained in this review.


  • Scope (Features to be tested, Features not to be tested are listed).


  • Terms of Acceptance Test (Conditions on which the system will be accepted i.e. points stated in acceptance terms must be in transit status).


  • Login / Exit Terms (Specifies the condition of when system testing should start and when it should be considered complete).


  • Test Schedule (Test rate will be completed from time to time).


  • Test Strategy (Includes test strategies).


  • Resources (Number of resources required for testing, their roles, availability of resources, etc.).


  • Test Environment (Operating System, Browser, Platform).


  • Test Cases (List of test cases to be performed).


  • Guess (If there is any guess, it should be included in the Test Program).
