Test techiniques

1. Unit Testing

   • Are tested for determine whether they are fit for use
     • Advantages
       • Find problems early ,Facilitates change ,Simplifies integration ,good Documentation ,Design
     • Disadvantages
       • Decision problem,not integration testing,Combinatorial problem,record keeping

2. White-box testing

   • In white-box testing an internal system perspective, as well as programming knowledge, is used to design test cases. The tester chooses inputs to exert paths through the code and determine the appropriate outputs.
     • Advantages
       • Side effects of having the knowledge of the source code is beneficial to thorough testing. ,Optimization of code by revealing hidden errors and being able to remove these possible defects ,Gives the programmer introspection because developers carefully describe any new implementation,Provides traceability of tests from the source, White box tests are easy to automate.
     • Disadvantages
       • White-box testing brings complexity to testing because the tester must have knowledge of the program,The tests focus on the software as it exists, and missing functionality may not be discovered

3. Error-Based testing

   • Is a Test on the execution revision of the functionalities previously designed for the software
     • consists
       • Concrete and exhaustive to test and validate that software does what it should and above all

4. Scenario-Based Testing

   • Scenario-Based assessment requires that you be able set up an evaluation committe
     • phases
       • Preparation
         • the evaluation is requested and an evaluation package is sent to the committee
       • evaluation
         • generally must include general information of the system ,detail of the requirements that influence the architecture
       • documentation
         • the documentation of the same through different views
