What is Software Testing and Why organization need Software Testing
In this article you will get the depth knowledge of software testing basics, It’s methods and techniques, levels and how it’s important.
Software Testing is the process of measuring or developing the quality and defect free products. In other words, software testing is an execution of the application to find a software bug, defects and errors also to check whether an actual result is a match with an expected result or not.
There are three types of testing
Manual Testing :
Manual Testing is the type of software Testing. It’s the most important and initial stage of testing. Manual testing is the process of testing software manually, run the test cases without using any automated tools. In manual testing tester first, write the all possible test cases after that execute one by one and check the actual result with an expected result if the result, not matches then tester pass these bug to the developer then the developer resolves the error and again tester test this bug and mark as defect solve. No one software tested 100% using automation tool, first of all, you have to check it manually.
There are different types of techniques that are performed manually during testing life cycle:
Acceptance Testing
Black Box Testing
White Box Testing
Unit Testing
System Testing
Integration Testing
Automation testing is the process to test the software using automation tools. In automation, testing tester writes a script and then run on a different tool to find the bug. In automation testing programs are run repeatedly and its save time, cost, and manpower. In automation testing test cases are run faster than manual testing. The main purpose of automation testing is to increase the test efficiency and develop a develop a defect-free software and increase its value.
Mobile Testing: Mobile Testing is the process to check the functionality of the application on different mobile devices and on the different operating system where it is working properly or not.
Software testing Levels :
There are different types of software testing levels mainly they are categorized into 2 parts:
- Functional Testing
2) Non-Functional Testing
Functional Testing can be performed by various types of testing
Unit Testing: Unit Testing perform on the small part of an application. In unit testing, testing is performed by the developer before the setup is handed over to the testing team.
Integration Testing: Integration testing is the next steps of unit testing. In integration testing, one or more parts test in a group to check the functionality of an application.
System Testing: In a system testing whole system check as one. In system testing application is tested thoroughly to verify that it meets the functional and technical requirements or not.
Acceptance Testing: After completing all types of testing acceptance testing will perform to check final quality and requirements of Application. Acceptance testing is done by quality assurance team.
These are the different types of software testing using these different types and tools every organization tests their application to develop a defect-free product.
But the first question arises is that every organization need software testing? Then the answer is “yes” because today’s world is a fastest growing technology world. Everyone uses internet, mobile, laptop etc. And competition going to increase day by day. Every customer wants their products updated in less time. They want more features in the application than their competitor. Also, they want defect free application. In an organization, the developer develops an application but they can’t test it within a short period of time both task can’t handle by developer simultaneously so find the errors tester plays a very important role in every organization. If you developed an application but can’t test properly then the value of your application in a market is zero. The Customer has high expectations from an organization. They wants quality products and quality is very important to gain confidence and trust.
Software testing is the one part of development life cycle. And it plays a very important role which helps to increase quality, reliability, and performance of the application.
Here I give you one example how software testing is important?
If you develop a bank application in which you maintain daily transaction account, loan account and all other types of transaction. If customer deposit RS 10000 in his account but your application take only 4 digits then system display 1000 and only RS 1000 is added to customer account so it’s a huge difference 1000 & 10000. Now how can you recover or solve this money difference? That’s why before going to market your application you have to test it properly means using all software technique.
