What is the software testing life cycle?

"Software testing life cycle (STLC) is a test strategy that helps business achieves quality software. STLC is focused on testing the software by following different phases of the software testing process. To give you a clear understanding of STLC we have explained the whole software testing lifecycle in brief below:

What is the software testing life cycle?
Software testing lifecycle is processes that have some steps that needed to be followed in sequence to ensure that software testing goals are met. In STLC each activity is carried out in a planned and systematic way to ensure that software testing goals are met.

What are the phases of the software testing lifecycle?
Below mentioned are the phases of the software testing lifecycle:

1.    Requirements phase – In this step, the requirement team analyses whether the requirements are testable or not. This helps to identify the scope of testing.
   

2.    Planning Phase – In this phase, teams plan the testing process and formulate strategy accordingly. Identification of activities, resources, and metrics is done in this step.  Risk analysis and risk mitigation are also done in this step. 
   

3.    Analysis phase – This phase defines ‘WHAT’ to be tested. Test conditions are identified through the requirements document, product risks, and other test bases.
   

4.    Design Phase –This phase defines the ‘HOW’ to test. In this phase the test condition is defined, test data is identified, the test environment is identified, test conditions are break into multiple sub-conditions to increase test coverage. 
   

5.    Implementation Phase- In this step the most critical process takes place, i.e.; test cases are identified, created, and prioritized. 
   

6.    Execution Phase- Test execution occurs during this phase. But before you conduct the test make sure that your entry criterion is met. Execute the test, log defects, and fill in your traceability metrics to track your progress. 
   

7.    Conclusion Phase –This phase focuses on exit criteria and reporting. Lay strong emphasis on reporting as it serves as a valuable piece of information for all involved stakeholders.
   

8.    Closure Phase- Check for the completion of the test and ensure that all the test cases are executed and mitigated deliberately. 
   

   Software testing lifecycle follows a sequence of steps of the test following which the software can be tested robustly. Leverage software testing from a next-gen QA and software testing services provider to get high-quality software."
