What is software testing? #3

1. a process consisting of all the testing cycle activities to determine that the software products satisfy requirements

   • done to find defects or failures

2. software testing is divided into 2 parts

   • testing as a process
     • testing is a process
       • not a standalone activitiy
         • a series of activites
           • done in all the phases of SDLC
     • testing is both static and dynamic
       • initial phases are static
         • tec review, walkthrough, inspection, static code analysis
       • once build is available, dynamic testing
         • unit testing, integration testing, system testing, acceptance testing
     • planning
       • most important part
         • what to achive?
         • who will do what?
         • time frame
         • control the test progress
         • prepare test summary reports
     • preperation
       • one plan is finalised, you need to do test preperation
         • prepare test cases
         • prepare test environment
         • prepare test data
     • evaluation
       • make sure it meets exit criteria
       • it is easy to use
       • meets requirements
     • software products and related work products
       • software requirements documents
       • design docs
       • reference guide
       • training materials
       • user guides
       • installation guide
   • objectives of testing
     • determine if software meets requirements
       • checks product against requirements
       • HLD reviewed to ensure it meets requirements and software validation is done to ensure it meets the design
       • testing ensures the product meets its specification and helps stakeholders make release decisions
     • demonstrate that software if fit for use
       • software testing demonstrates that the software is fit for use
       • testing is done to ensure that the software is fit for the end user
       • ensures it does what the software does what the user expects it to do
     • find bugs / defects
       • fixing them improves the quality of the software
       • root cause analysis of defects found by testing, improves the software development process
