Unit testing in software engineering: This is a test of an individual unit or group of related units. This white box comes under testing class. A programmer does this to test a particular unit. This test is very effective because most bugs or errors are identified by its use.

Software Engineering Notes

Unit testing in software engineering


For example, we are working on an application, in this application we have to create a calculator.

Since the calculator has a variety of functions such as: - Add, Subtract, Multiply division, etc.

We will divide this calculator developed by the programmer into several parts, including add, subtract, multiply, divide, and so on. We will call all these actions. Also, subtraction, multiplication, division are all units,

Now, these units will be tested one by one by each testing programmer.

Benefits of unit testing

  • It reduces power bugs by creating new programs or existing functionality.
  • Reduces bugs when switching.
  • Reduces the cost of testing after the insect is caught at a very early stage
  • Are taken Improves design and allows better refactoring of code. Unit Test, when integrated with build, also provides build quality.


Formal Technical Review


FTR is a quality assurance activity performed by a software engineer. It involves the analysis of the final product (software) by a group of technically skilled people after the technical and documentation process.

The purpose of F.T.R

To expose errors in function logic or process for any representation of software F.T.R is an effective method.

  • This makes the project more manageable.
  • It also ensures that the software is displayed according to default standards.
  • Verifying software requirements.
  • To spoil the mistakes.
  • And to see if the software is properly developed.
  • Ensure that software products are represented according to default standards and to make the project more organized.

Software Best Quality Assurance


The process of assuring the quality of the software is called software quality assurance (software quality assurance) or the software within which we are developing the quality.

Where to Use Software Quality Assurance:

Whatever software we create is done through a lot of development processes, so what is the stage of development of this software quality assurance?

Software quality assurance is not tested at any particular stage; it runs simultaneously with software development. Software quality assurance is checked after each development process.

If we develop software without software quality assurance and our software is fully developed and we will test it at the end, and if there are any errors or omissions during the test, In that case, our software will crash completely. Therefore, software assurance should be tested after every development process.


Why organizational people ignore this

  1. It takes more time to check the quality assurance of software: - In some companies software quality assurance is not checked because it takes more time to check.
  2. High cost to test software quality assurance: - More developers will be needed to test software quality assurance, so the company will spend more money.

How SQA is beneficial


Save money: - If we make low-quality software then we have to spend money, again and again, to maintain it, if we make good quality software then we get excellent reviews from the user. And we get no more money. Spend on this software.

High-quality application: - If we take the quality assurance of the software with us and move on to further development stage, then the customer will be ready to become high quality software.

Save time and money: - High-quality application saves both time and money.

Ease of use: - The software can be run easily, i.e. the user interface of the software should be better.

Design: - The design of the software should be good because the user will be attracted to the software when its design is better.

Speed: - The software should provide its services in the lost time, i.e. its speed should be fast.

Security: - The software should be secured i.e. who can see and process the data contained in the software? If there is any software based on internet, then it should have encryption and decryption.


Its other benefits are as follows: -

Error-free: - The software should be error-free because if there are errors in the software then the reliability and security of the software will be reduced due to which this software will fail.

Portable: - The software should be portable, i.e. the software should run smoothly in other environments.

Testing: Testability means that the software can be easily tested.

Maintenance: - This means that if we need to make any changes to the software, we can do it easily.

Readability: - The source code of the software should be readable i.e. it can be read easily.

Reliability: - Software should be reliable, i.e. software that should be stable on its performance.

Functionality: Functionality means that the software should have functions based on the user's needs so that the user can work in it easily.
