Why software testing is necessary?

Software testing is one of the internationally aspired domains in the current age. It is a process with the intent of finding defects in a computer program and software testing is done by a Software Tester.

Software Testing Life Cycle

It is a sequence of activities performed for software testing. It recognizes what test activities to perform and when to accomplish those test activities. In this process, each activity is carried out in a planned and systematic way, and each phase has different goals and deliverable.

Stages of Software Testing Life Cycle

• Requirement Analysis
• Test Planning
• Test Case Development
• Environment Setup
• Test Execution
• Test Cycle Closure

Software Testing can be done by two methods known as:

Manual Testing :

It is the oldest & best method to test the software. In “Manual Testing” Tester analyze all the software related documents like test plan documents, design documents, source code, test case documents, and test software manually & try to find out errors.

Automation Testing :

It is the latest & well-known Testing method used by Software Testing Companies that is Automation Testing. In this testers use software testing tools to test software, tester just has to do is “Writing Test Cases” & execute using the tool.

Automation testing can perform by using test cases tester, without test cases tester can not execute or test software. To perform automation testing companies required a high budget. Mostly automation testing not used for the small project.

Need for Software testing

• It is required to point out the defects and flaws that were made during the development phases.
• It’s necessary since it makes sure that the client finds the company reliable and their satisfaction in the application is maintained.
• Important to ensure the Quality of the product. Quality product delivered to the clients helps in gaining their confidence.
• Testing is necessary to give the facilities to the clients like the high quality product or software application which requires lower maintenance cost and hence results into more accurate, consistent and reliable results.
• It’s important to ensure that the application should not result into any failures because it can be very expensive in the future or the later stages of the development.
• It’s required to stay in the business.
