  1. 1. Testing Life Cycle Presenter - Praveen Reddy K. Date- NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 0
  2. 2. Targeted Audience • Anybody who is new to testing and want to know the Test Life Cycle • Testers who has experience in Adhoc -Testing but want to learn the formal processes and procedures in Software Testing NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 1
  3. 3. Course Content • • • • • • • • • • Define Software Testing? Why Software Testing and a specialist for Testing? Software Testing in SDLC Test Planning Test Design Test Execution and Process V- Model Bug Life Cycle Testing Documentation and Formats. Guide Lines and Check Lists NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 2
  4. 4. What is Software Testing? • Testing is the process of proving that a piece of software works as specified • IEEE Terminology: An examination of the behavior of the program by executing on sample data sets • Testing comprises of a set of planed activities which result in identification of defect if any • Testing involves operation of a system or application under controlled conditions and evaluating the results. • The goal of the testing activity is to find – As many Errors as possible before the user of the software finds them. – To determine whether a program component meets its requirements. NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 3
  5. 5. Why Software Testing? • • • • To uncover defects in the Software To analyse the reliability of the Software To ensure that Software works as user expected Early detection of defects and thus to reduce the cost & deliver the Software with acceptable quality • To collect the Metrics which will help to plan the future projects effectively. Why Software Testers? • One can’t find his own faults so as Developers • A fresh brain is the best brain • To have systematic and complete testing NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 4
  6. 6. Software Testing in SDLC Business Requirements Technical Feasibility Analysis Schedule Financial Project Plan System Requirement System Requirements Functional Requirements UI Functional Environment Performance Security Test Plan Design UI Design DB Design App Design High Level Design Test Case Design Coding Traceability Low Level Design Matrix Testing Release and Maintenance Problems Change Requests NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 5

Test Planning • • A document to describe the plan for “What to Test?”, “How to Test?” and “When to Test?” Test Plan Template – – – – – – – – Title Revision History Objective of the Document Scope of the Document Objective of Testing Brief Description of the Project Test Environment Critical Functionalities NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 6
  8. 8. Test Planning (Continues..) • Test Plan Template (Continues) – – – – – – – – Functionality not to be tested Test data requirement and collection Automation Analysis Test Strategy Training Plan( Technical/ Domain/ Softskill) Effort Estimation Resource Requirement ( HR/SW/HW) Scheduling ( Detailed schedule for all phases of Testing) NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 7

Test Planning (Continues..) • Test Plan Template (Continues) – – – – – – – – – Input Criteria Exit Criteria Acceptance Criteria Test Suspension & Resumption Criteria Test Completion Criteria Test Deliverables Bug Classifications Bug Tracking Test Metrics to be collected Documents Referred NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 8
  10. 10. Test Design • The process of identifying the test conditions and preparing test cases • Test Design involves: – Identifying the Test Conditions – Preparation of Test Scenarios – Preparation of Test Cases – Preparation of Test Scripts – Preparation Traceability Matrix (RTM) NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 9
  11. 11. Test Design (Continues..) • Test Condition: Every testable requirement is considered as a Test Condition • Test Scenario: The Test Condition which covers one high level requirement or business transaction is called as Test Scenario NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 10
  12. 12. Test Design (Continues..) • Test Case: The set of test steps to be performed along with expected result to test a low level requirement is called as Test Case • Test Scripts: The programs developed to test the application are called as Test Scripts • Traceability Matrix: The mapping developed between different information sources like : Requirements Test cases Test Scripts Defects NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 11
  13. 13. Test Execution& Process - 1 • Test Process Depends on the Project Development Model • Projects are: – Development Projects • Classical Development • Incremental Development • Modular Development – Maintenance Projects NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 12

  19. 19. Advantages of V Model over Water Fall Model • V Model: – A detailed model with description of all the phases – Allows parallel test activities during development activities – Depicts the dependency of Test Phases on other development phases NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 18
  20. 20. V-Shaped Model • The high-level design phase • V-Shaped life cycle is a focuses on system architecture sequential path of execution of and design. An integration test processes. Each phase must be plan is created in this phase. completed before the next phase begins • The low-level design phase is where the actual software • Business Requirements (BRS) components are designed, and begin the life cycle model. unit test plan is created in this Acceptance Test Plan is created phase as well. based on Business Requirements. • The implementation phase is, again, where all coding takes • After BRS, System Requirements place. Once coding is complete, will be collected. Based SRS, the path of execution continues System Test Plan is created. The up the right side of the V where test plan focuses on meeting the the test plans developed earlier functionality specified in the are now put to use. requirements gathering. NCT-Mind Q Proprietary 3/12/2008 5:38:45 PM 19
  21. 21. Verification and Validation Verification and Validation (V&V) is a Software Testing activity to enhance quality of the software being built. It is planned and conducted systematically through out the software lifecycle. • Verification: Are we building the Project right? – • Verification is the checking or testing of items, including software, for conformance and consistency with an associated specification. Reviews, Analysis, Meetings and walkthroughs. Validation: Are we building the right product?. – Validation begins when most or all software functions are as per customer expectations. Validation testing provides final occurrence that the software meets all functional, behavioral and performance requirements. Usually testing is used for this activity.
