Part 1, Intro on testing

Software Testing Purpose

Prove that your software works

Show that your software DOES NOT work

What should I test for?

Code (technical errors) Functionalities (business logic errors) Compatibility (cross-browser issues) Performance (speed) Security Usability: is it easy to use

Methods

  • Manual
  • Unit testing

    Test a small unit of code, such as a function

  • Integration testing

    Test the entire stack

Recurring testing challenges

Time & effort
  • To write tests
  • To maintain tests

    Tests become obsolete as code evolves

Insufficient coverage
  • Difficult to cover all paths of a program

BugBuster's technology

Dynamic Analysis of HTML & JavaScript Enables generation of test cases from code

i.e. new input sequences for covering more paths

Useful with Unit tests & Integration tests

Reduce effort, Improve coverage, Improve quality
