  • Your Partner for Professional Successhttp://www.techpartnerz.comValidation Strategies…in detailValidationStrategyExplanation DeliverableUnit Testing Testing of single program, modules, orunit of code.Software unit readyfor testing with othersystem component.IntegrationTestingTesting of related programs, modules, orunits of code.Portions of the systemready for testing withother portions of thesystem.SystemTestingTesting of entire computer system. Thiskind of testing can include functional andstructural testing.Tested computersystem, based onwhat was specified tobe developed.PerformanceTestingTesting of the application for theperformance at stipulated times andstipulated number of users.Stable applicationperformance.

  • Your Partner for Professional Successhttp://www.techpartnerz.comIn order to establish software testing methodology anddeveloping the framework for developing the testingtactics,the following eight considerations should be described: Acquire and study the Test Strategy. Determine the Type of Development project. Determine the Type of Software System. Determine the project scope. Identify the tactical risks. Determine when testing should occur. Build the system test plan. Build the unit test plan.Establishing a Software Testing Methodology.

  • Your Partner for Professional Successhttp://www.techpartnerz.comTesting can and should occur throughout the phases of a project.Requirements Phase• Determine the test strategy.• Determine adequacy of requirements.• Generate functional test conditions.Design Phase• Determine consistency of design with requirements.• Determine adequacy of design.• Generate structural and functional test conditions.Program (Build) Phase• Determine consistency with design.• Determine adequacy of implementation.• Generate structural and functional test conditions forprograms/units.When Testing should occur..?
  • Your Partner for Professional Successhttp://www.techpartnerz.comTest Phase• Determine adequacy of the test plan.• Test application system.Installation Phase• Place tested system into production.Maintenance Phase• Modify and retest.When Testing should occur..?
  • Your Partner for Professional Successhttp://www.techpartnerz.comTwo types of testing can be taken into consideration. Functional or Black Box Testing. Structural or White Box Testing.Functional testing ensures that the requirements areproperly satisfied by the application system. Thefunctions are those tasks that the system is designed toaccomplish.Structural testing ensures sufficient testing of theimplementation of a function.Types of Testing.
  • Your Partner for Professional Successhttp://www.techpartnerz.comStructural Testing.Technique Explanation ExampleStress Determine system performancewith expected volumes.Sufficient diskspace allocated.Execution System achieves desired level ofproficiency.Transactionturnaround timeadequate.Recovery System can be returned to anoperational status after a failure.Evaluate adequacyof backup data.
  • Your Partner for Professional Successhttp://www.techpartnerz.comStructural Testing.Technique Explanation ExampleOperations System can be executed in anormal operational status.Determine systemscan run usingdocument.Compliance System is developed inaccordance with standards andprocedures.Standards follow.Security System is protected inaccordance with importance toorganization.Access denied.

Prove systemrequirements.Regression Verifies that anythingunchanged still performscorrectly.Unchanged systemsegments function.Error Handling Errors can be prevented ordetected and then corrected.Error introducedinto the test.
  • Your Partner for Professional Successhttp://www.techpartnerz.comFunctional Testing.Technique Explanation ExampleManualSupportThe people-computer interactionworks.Manual proceduresdeveloped.Inter Systems Data is correctly passed from systemto system.Intersystem parameterschanged.Control Controls reduce system risk to anacceptable level.File reconciliationprocedures work.Parallel Old systems and new system are runand the results compared to detectunplanned differences.Old and new system canreconcile.
