Static Testing Vs Dynamic Testing

Static Testing 
  • Static testing is the testing of the software work products manually, or with a set of tools, but they are not executed.
  • It starts early in the Life cycle and so it is done during the verification process.
  • It does not need computer as the testing of program is done without executing the program. For example:  reviewing, walk through, inspection, etc.
  • Most static testing techniques can be used to ‘test’ any form of document including source code, design documents and models, functional specifications and requirement specifications.
Dynamic Testing
  • This testing technique needs computer for testing.
  • It is done during Validation process.
  • The software is tested by executing it on computer. Ex: Unit testing, integration testing, system testing.

Testing Techniques used for Static Testing:

  • Informal Reviews: This is one of the type of review which doesn't follow any process to find errors in the document. Under this technique , you just review the document and give informal comments on it.
  • Technical Reviews: A team consisting of your  peers,   review the technical specification of the software product and checks whether it is suitable for the project. They try to  find any discrepancies in the specifications and standards followed. This review concentrates mainly on the technical document related to the software such as Test Strategy, Test Plan and requirement specification documents.
  • Walkthrough: The author of the work product explains the product to his team. Participants can ask questions if any.  Meeting is led by the author. Scribe makes note of review comments
  • Inspection: The main purpose is to find defects and meeting is led by trained moderator. This review is a formal type of review where it follows strict process to find the defects. Reviewers have checklist to review the work products .They record the defect and inform the participants to rectify those errors.
  • Static code Review: This is systematic review of the software source code without executing the code. It checks the syntax of the code, coding standards, code optimization, etc. This is also termed as white box testing .This review can be done at any point during development.
Testing Techniques used for Dynamic Testing:  
  • Unit Testing:Under unit testing ,  individual units or modules is  tested by the developers. It  involves testing of source code by developers.
  • Integration Testing: Individual modules are grouped together and tested by the developers. The purpose is to determine that modules are working as expected once they are integrated.
  • System Testing: System testing is performed on the whole system by checking whether the system or application meets the requirement specification document.
