Software Testing Life Cycle - STLC

Phases of STLC


  • Requirement Analysis - In this phase the requirements documents are analysed and validated. Along with that the scope of testing is defined.
  • Test Planning and Control - Test planning is one of the most important activities in test process. It involves defining the test specifications in order to achieve the project requirements. Whereas, test Control includes continuous monitoring of test progress with the set plan and escalating any deviation to the concerned stake holders.
  • Test Case Development - This phase involves the actual test case creation. It also invloves specification of test data and automated test scripts creation.
  • Test Environment Setup - This phase involves creation of a test environment closely simulating the real world environment.
  • Test Execution - This phase involves manual and automated test case execution. During test case execution any deviation from the expected result leads to creation of defects in a defect management tool or manual logging of bugs in an excel sheet.
  • Exit Criteria Evaluation and Reporting - This phase involves analyzing the test execution result against the specified exit criteria and creation of test summary report.
  • Test Closure - This phase marks the formal closure of testing. It involves checking if all the project deliverable are delivered, archiving the testware(everything involved in testing like test plan, test case, automation scripts), test environment and documenting the learning.
