System Testing & It’s Type

Testing of an entire integrated software system is a part of system testing. Generally speaking, software integration creates a computer system (the software itself is merely one component of a computer system). The software is constructed in modules and interfaced with hardware and other software to build a whole computer system. To put it another way, a computer system is made up of a collection of software that together may do different jobs. However, software alone is not sufficient to complete a task; rather, software and hardware must be interfaced. System testing is a collection of several tests designed to exercise and assess an integrated software computer system’s overall functionality in comparison to requirements.

What do you verify in System Testing?

System testing includes checking the following in the program code:

• To verify how parts work with one another and the system as a whole, test the fully integrated apps with external peripherals. Another name for this is an end-to-end testing scenario.
• Ensure to thoroughly test each input in the application to make sure the intended results are produced.
  I am testing the application’s interaction with the user.
• That sums up system testing’s components in very simple terms. Without examining the source code, you must create comprehensive test cases and test suites that evaluate every feature of the program as it appears to the outside world. Read up on end-to-end testing to find out more about an all-encompassing method for this procedure.

Hierarchy of Testing Levels:

Software testing is mostly done using two approaches: white box testing, which creates test cases using internal coding, and black box testing, which creates test cases using a graphical user interface or user perspective.

• White box testing
• Black box testing

Black box testing includes testing the software’s exterior functionality, which is what system testing relates to. Testing looks at things from the user’s point of view to find small flaws.

The following procedures are part of system testing:

• Verification of the application’s input functions to determine whether or not the intended output is being produced.
• Integrating external peripherals during software testing allows you to see how different components work together.
• End-to-end testing involves testing the entire system.
• Utilizing Auser’s experience to assess the application’s behavior

Process for System Testing:

The following steps are involved in System Testing:

• Setup test environment: Configure the testing environment to ensure higher-quality testing.
• Construct Test Case: For the testing procedure, create a test case.
• Produce Test Data: Produce the data that will be examined.
• Execute Test Case: Test cases are carried out following the creation of the test case and test data.
• Defect Reporting: The system detects flaws.
• Regression Testing: Testing the consequences of the testing procedure is done through regression testing.
• Log Defects: In this stage, errors are corrected.
• Retest: A second test is conducted if the first one is unsuccessful.

Types of System Testing:

Over fifty different forms of system testing exist. Click here for a comprehensive list of software testing kinds. The forms of system testing that a large software development company would normally use are outlined below.

• Usability testing: Usability testing primarily looks at how easy it is for the user to use the application, how flexible the controls are, and how well the system works to achieve its goals.
•  Load testing: To ensure that a software solution will function under actual demands, load testing is required.
• Regression testing: Testing to ensure that no changes made throughout the development process have resulted in the emergence of new bugs is known as regression testing. Additionally, it ensures that no outdated bugs arise from the gradual installation of new software modules.
•  Recovery testing: The purpose of recovery testing is to show that a software solution is dependable, trustworthy, and capable of recovering from potential crashes.
• Migration testing: The purpose of migration testing is to make sure that there are no problems while transferring software from outdated to more modern system infrastructures.
• Functional testing: Functional testing, also referred to as functional completeness testing, entails attempting to identify any potential functional gaps. During functional testing, testers may compile a list of potential features that a product should have to enhance it.
•  HW/SW Testing: IBM refers to the process of testing software and hardware together as “HW/SW Testing.” During system testing, this is the time when the tester concentrates on the interactions between the hardware and software.

Benefits of Conducting System Testing:

• To do this testing, the testers don’t need any additional programming expertise.
• To readily identify mistakes or defects that are not visible during unit testing and integration testing, the entire product or software will be tested.
• The real-time production or commercial environment is comparable to the testing environment.
• It encompasses the technical and business needs of clients in addition to testing the system’s overall functionality using various test scripts.
• The product will have nearly eliminated all faults and mistakes after this testing, so the development team may move forward with acceptance testing with confidence.

The drawbacks to system testing:

• Since this testing involves checking the complete program or product, it takes longer than other testing methods.
• Since the complete software will be tested, the cost of the testing will be significant.
• If a decent debugging tool is not used, the concealed errors will remain undetected.
