  • 1. Software Testing Life Cycle [STLC] BY: P2CINFOTECH
  • 2. WHAT IS SOFTWARE TESTING?    Software Testing is a process that consists of all test life cycle activities like static and dynamic testing concerned with planning, preparation and evaluation of software products to determine that the software products satisfy customers requirements and are fit for customers use. Software Testing is done to find software defects or failures in advance. Testing involves any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. www.p2cinfotech.com +1-732-546-3607
  • 3. SOFTWARE TESTING   Software testing can also be stated as the process of validating and verifying that a software program/application/product: 1. Meets the business and technical requirements that guided its design and development. 2. Works as expected; and 3. Can be implemented with the same characteristics. Testing is an iterative process i.e. If defect is found and fixed, testing needs to be done after every defect fix. www.p2cinfotech.com +1-732-546-3607
  • 4. SOFTWARE TESTING LIFECYCLE [STLC]   The process of testing a software in a well planned and systematic way is known as software testing lifecycle (STLC). Different organizations have different phases in STLC however generic Software Test Life Cycle (STLC) for waterfall development model consists of the following phases. 1. Requirements Analysis 2. Test Planning 3. Test Analysis 4. Test Design 5. Test Construction and Verification 6. Test Execution and Bug Reporting 7. Final Testing and Implementation 8. Post Implementation www.p2cinfotech.com +1-732-546-3607
  • 5. ARCHITECTURE OF STLC
  • 6. OVERVIEW OF STLC PHASES Phases Activity Deliverables Necessity Requirements/Design You review the software requirements/design •Review Defect •Reports Curiosity Test Planning Once you have gathered a general idea of what needs to be tested, you ‘plan’ for the tests. •Test Plan •Test Estimation •Test Schedule Farsightedness Test Designing You design/detail your tests on the basis of detailed requirements/design of the software •Test Cases/Test Scripts/Test Data •Requirements Traceability Matrix Creativity Test Environment Setup You setup the test environment (server/client/network, etc) with the goal of replicating the endusers’ environment. •Test Environment Rich company Test Execution You execute your Test Cases/Scripts in the Test Environment to see whether they pass. •Test Results •Defect Reports Patience Test Reporting You prepare various reports for various stakeholders. •Test Results (Final) •Test/Defect Metrics •Test Closure Report Diplomacy
  • 7. PHASES IN STLC    Phase 1 [ Requirements Analysis ]: In this phase testers analyze the customer requirements and work with developers during the design phase to see which requirements are testable and how they are going to test those requirements. It is very important to start testing activities from the requirements phase itself because the cost of fixing defect is very less if it is found in requirements phase rather than in future phases. www.p2cinfotech.com +1-732-546-3607
  • 8. PHASES IN STLC     Phase 2 [ Test Planning ]: In this phase all the planning about testing is done like what needs to be tested, how the testing will be done, test strategy to be followed, what will be the test environment, what test methodologies will be followed, hardware and software availability, resources, risks etc. A high level test plan document is created which includes all the planning inputs mentioned above and circulated to the stakeholders. Usually IEEE 829 test plan template is used for test planning. www.p2cinfotech.com +1-732-546-3607
  • 9. PHASES IN STLC     Phase 3 [ Test Analysis ]: After test planning phase is over test analysis phase starts, in this phase we need to dig deeper into project and figure out what testing needs to be carried out in each SDLC phase. Automation activities are also decided in this phase, if automation needs to be done for software product, how will the automation be done, how much time will it take to automate and which features need to be automated. Non functional testing areas(Stress and performance testing) are also analyzed and defined in this phase. www.p2cinfotech.com +1-732-546-3607
  • 10. PHASES IN STLC    Phase 4 [ Test Design ]: In this phase various black-box and white-box test design techniques are used to design the test cases for testing, testers start writing test cases by following those design techniques. If automation testing needs to be done then automation scripts also needs to written in this phase. www.p2cinfotech.com +1-732-546-3607
  • 11. PHASES IN STLC     Phase 5 [Test Construction and Verification]: In this phase testers prepare more test cases by keeping in mind the positive and negative scenarios, end user scenarios etc. All the test cases and automation scripts need to be completed in this phase and got reviewed by the stakeholders. The test plan document should also be finalized and verified by reviewers. www.p2cinfotech.com +1-732-546-3607
  • 12. PHASES IN STLC      Phase 6 [Test Execution and Bug Reporting]: Once the unit testing is done by the developers and test team gets the test build, The test cases are executed and defects are reported in bug tracking tool, after the test execution is complete and all the defects are reported. Test execution reports are created and circulated to project stakeholders. After developers fix the bugs raised by testers they give another build with fixes to testers, testers do re-testing and regression testing to ensure that the defect has been fixed and not affected any other areas of software. After tester assures that defects have been fixed and no more critical defects remain in software the build is given for final testing. www.p2cinfotech.com +1-732-546-3607
  • 13. PHASES IN STLC    Phase 7[Final Testing and Implementation]: In this phase the final testing is done for the software, non functional testing like stress, load and performance testing are performed in this phase. The software is also verified in the production kind of environment. Final test execution reports and documents are prepared in this phase. www.p2cinfotech.com +1-732-546-3607
  • 14. PHASES IN STLC    Phase 8 [ Post Implementation ]: In this phase the test environment is cleaned up and restored to default state, the process review meeting’s are done and lessons learnt are documented. A document is prepared to cope up similar problems in future releases. www.p2cinfotech.com +1-732-546-3607
  • 15. SDLC VS STLC SDLC STLC SDLC is Software Development LifeCycle, it is a systematic approach to develop a software. The process of testing a software in a well planned and systematic way is known as software testing life cycle(STLC). Requirements gathering Requirements Analysis is done is this phase, software requirements are reviewed by test team. Design Test Planning, Test analysis and Test design is done in this phase. Test team reviews design documents and prepares the test plan. Coding or development Test construction and verification is done in this phase, testers write test cases and finalizes test plan. Testing Test Execution and bug reporting, manual testing, automation testing is done, defects found are reported. Re-testing and regression testing is also done in this phase. Deployment Final testing and implementation is done is this phase and final test report is prepared. Maintenance Maintenance testing is done in this phase. www.p2cinfotech.com +1-732-546-3607
