Software Testing Life Cycle

What is software testing ?

Software testing is the most common way of assessing a software item or application to identify any imperfections or issues before it is delivered to the market or sent. It includes directing different tests and analyses on the software to guarantee that it meets the prerequisites and details given by the client or end-clients. The objective of software testing is to distinguish and fix any issues with the software to guarantee that it is of great capabilities as planned.

Principles of software testing

1.Thorough testing is inconceivable:

It is difficult to test all potential mixes of data sources, client ways of behaving, working frameworks, and different elements, so analyzers need to focus on their testing endeavors in light of chance, need, and different variables.

2.Testing early and frequently: 

Testing ought to be integrated into the software advancement lifecycle all along and ought to be performed ceaselessly all through improvement, testing early and frequently assists with distinguishing issues and keeping them from expanding issues down the line.

3.100 percent without bug software is ridiculous: 

Notwithstanding best endeavors, software engineers and analyzers won’t ever accomplish flawlessness. It is critical to know the sorts of bugs that are adequate, for example, minor UI issues, and know when it’s ideal to fix the bugs as opposed to work around them.

4.Mechanization ought to utilized whenever the situation allows: 

Robotization tests make the testing system quicker, more proficient, and more solid. In any case, it is essential to adjust robotization and manual testing to guarantee that the two strategies tilized accurately.

5.Test climate ought to imitate creation: 

Test conditions ought to be indistinguishable from creation conditions to distinguish issues that might happen in reality. Testing in an alternate climate can present fake situations that don’t mirror this present reality.

6.Detectability and inclusion: 

It is crucial for record experiments and prerequisites to guarantee total inclusion of the testing system. This assists with monitoring what still needs testing to guarantee all distinguished dangers have been tried.

7.Openness is absolutely vital: 

Analyzers ought to actually discuss with engineers and different partners to determine issues, stay away from suspicions, and guarantee that everybody grasps the undertaking prerequisites, needs, and timetables.

7 steps in software testing life cycle

Software testing life cycle is a process that describes testing methods and techniques for software development. It is an essential aspect of software development to ensure the software meets client requirements and expectations. It involves planning, executing, analyzing, and reporting testing activities. The following is a detailed explanation of software testing life cycle in 1000 words.

Test Planning:

The first step of a software testing life cycle is test planning. In this step, a testing team defines the objectives of testing, identifies test objectives, and determines the testing scope. The team creates a test plan that outlines the testing strategies, approaches, timelines, and resources required for testing. The test plan also includes the identification of the types of software testing and testing tools that will be used.

Test Design:

In the second step of the software testing life cycle, the testing team develops a test design. The purpose of this step is to create a plan that determines what test cases should be executed to achieve the test objectives. The testing team designs the test cases to cover all the functional requirements and non-functional requirements of the software. The test design includes the identification of test scenarios, test cases, and test data.

Test Execution:

Test execution is the third step in the software testing life cycle. In this step, the testing team executes the test cases based on the test design. The team uses the test data that  prepared in the test design step to execute the test cases. The testing team captures all the testing results and reports them to the development team. During the test execution, the testing team may identify software defects or issues.

Test Analysis:

In the fourth step of the software testing life cycle, the testing team analyzes the testing results. The team reviews and evaluates the defects identified during the test execution. The team determines the root cause of the defects and reports them to the development team. The testing team validates the defect fixes provided by the developers.

Test Reporting:

The fifth step in the software testing life cycle is test reporting. In this step, the testing team reports the testing results to the stakeholders. The team provides the status of the testing progress, defects identified, and test results. The testing team reports the test results to the development team, management, and clients.

Retesting and Regression Testing:

After the defects fixed, the software retested to validate if the fixes successful. The testing team executes the test cases on the modified software to ensure the defects resolved. Regression testing is conducted to test the software after modifications to ensure the new code does not impact the existing functionality.

Test Closure:

The final step of the software testing life cycle is test closure. In this step, the testing team completes all the testing activities, analyzes the final testing results and prepares the test closure report. The report summarizes the testing process, provides final testing results, lessons learned, and recommendations for future testing projects.


Software testing life cycle is an essential process in software development. It ensures the software meets client requirements, is defect-free, and functions as intended. The testing team performs several steps to ensure the software is of high quality, including test planning, test design, test execution, test analysis, test reporting, retesting, regression testing, and test closure. It is important that the software testing life cycle followed, and all test cases executed to ensure software quality.
