STLC (Software Testing Life-cycle)

• STLC refers to a testing process which has specific steps to be execute in a definite sequence to ensure that the quality goals have been met.
• In the STLC process each activity is carried out in a Planned and systematic way. 
• Each Phase has different goals and deliverable.
• It helps in making the software defects free.

Software Testing Life Cycle: 

Requirement Analysis: 

Requirement Analysis is the first step in Software Testing Life Cycle. In this step Quality Assurance team understands the requirement in terms of what we will testing & figure out the testable requirements.

Test Planning:

Test Planning is most important phase of Software testing life cycle where all testing strategy is defined. This phase also called as Test Strategy phase.

Define the scope of the project like 

• Perform test estimation.
• Determine the over all testing strategy & process.
• Identify the tools and resources.

Test Case Design:

It defines "How to Test". The test case development activity is started once the test planning activity is finished.
