What is Software Testing?

What is Software Testing?

SOFTWARE TESTING is defined as  activity to check whether the Actual results match the Expected results and to ensure that the software system is Defect / Bug free (as per customer requirement) . 

Software testing also helps to identify errors, gaps, or missing requirements in contrary to the actual requirements. It can be either done manually or using automated tools. Some prefer saying Software testing as a White Box (Testing done by Analyzing code) and Black Box Testing(Testing done by Analyzing application as per user without digging into the code. Example Verifying login form of application).

In simple terms, Software Testing means the Verification of Application Under Test (AUT).


Importance of Software Testing 

Normal Trend ---In today's time there are plenty of startups and low budget software companies who donot prefer Software Tester in their company  as it is a extra burden as per wages and other extra facility which they have to provide then to person who find out bugs in software developed by Developer. They   ask their developers to test the application once developed. This is very easy in the case if Application in simple, Sorted and Small. However if the application is huge and complex and a dedicated team is mandatory to test the application to avoid rework and complete the work within timeline.

Testing is important because software bugs could be expensive or even dangerous. Software bugs can potentially cause monetary and human loss, and history is full of such examples.

Some of Amazon's third-party retailers saw their product price is reduced to 1p due to a software glitch. They were left with heavy losses.

In April of 1999, a software bug caused the failure of a $1.2 billion military satellite launch, the costliest accident in history.


What are the benefits of Software Testing?

Here are the benefits of using software testing:

  • Cost-Effective: It is one of the important advantages of software testing. Testing any IT project on time helps you to save your money for the long term. In case if the bugs caught in the earlier stage of software testing, it costs less to fix.
  • Security: It is the most vulnerable and sensitive benefit of software testing. People are looking for trusted products. It helps in removing risks and problems earlier.
  • Product quality: It is an essential requirement of any software product. Testing ensures a quality product is delivered to customers.
  • Customer Satisfaction: The main aim of any product is to give satisfaction to their customers. UI/UX Testing ensures the best user experience.

Types of Software Testing

Typically Testing is classified into three categories.

  • Functional Testing
  • Non-Functional Testing or Performance Testing
  • Maintenance (Regression and Maintenance)


Testing Strategies in Software Engineering

Here are important strategies in software engineering:

Unit Testing: This software testing approach is followed by the programmer to test the unit of the program. It helps developers to know whether the individual unit of the code is working properly or not.

Integration testing: It focuses on the construction and design of the software. You need to see that the integrated units are working without errors or not.

System testing: In this method, your software is compiled as a whole and then tested as a whole. This testing strategy checks the functionality, security, portability, amongst others.

DIFFERENCE BETWEEN DEFECT , BUG, ERROR AND FAILURE

Image
DIFFERENCE BETWEEN DEFECT , BUG, ERROR AND FAILURE  DEFECT: If  difference exist  between actual result and expected result  and that difference is found by developer and  corrected by himself in the development phase then it’s called a defect.   Example if developer  has developed  a code  and while performing (Unit Testing) developed  found that the code is not functioning  as per requirement  then in tat case the issue occurred  is known as DEFECT. BUG: If testers find any mismatch in the application/system in testing phase then they call it as Bug. Example if the developer has done the development  and performed Unit testing of a login form then the module is sent to Tester for performing testing. In this phase if tester found that the client requirement is not matching with the  result of application then tester report it as Bug.  NOTE:  there is a contradiction in the usage of Bug and Defect. People widely say the bug is an informal name for the defect. ERROR If we can’t compile

Software Testing Life Cycle (STLC)?

Image
STLC(SOFTWARE TESTING LIFE CYCLE) It is a sequence of specific activities conducted during the testing process to ensure software quality goals are met. STLC involves both verification and validation activities. Contrary to popular belief, Software Testing is not just a single/isolate activity, i.e. testing. It consists of a series of activities carried out methodologically to help certify your software product. STLC stands for Software Testing Life Cycle. PHASES OF STLC : Requirement Analysis Test Planning Test case development Test Environment setup Test Execution Test Cycle closure What is Entry and Exit Criteria? Entry Criteria:  Entry Criteria gives the prerequisite items that must be completed before testing can begin. Exit Criteria:  Exit Criteria defines the items that must be completed before testing can be concluded. Requirement Analysis During this phase, test team studies the requirements from a testing point of view to identify the testable requirements. The QA team may in

SOFTWARE DEVELOPMENT LIFE CYCLE MODELS (SDLC MODEL)

Image
A software life cycle model is a descriptive representation of the software development cycle. SDLC models might have a different approach but the basic phases and activity remain the same for all the models. 1) Waterfall Model 2) V-Shaped Model 3) Prototype Model 4) Spiral Model 5) Iterative Incremental Model  6) Big Bang Model 7) Agile Model Waterfall Model The  Waterfall Model  was the first Process Model to be introduced. It is very simple to understand and use it. In a  Waterfall  model, each phase must be completed before the next phase can begin and there is no overlapping in the phases.  The waterfall  model is the earliest  SDLC   approach that was used for software development. n “ The Waterfall ” approach, the whole process of  software development  is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the development process begins only if the previous phase is complete. The waterfall model
