 Functional Testing

 Ø       Study SRS

Ø       Identify Unit Functions

Ø       For each unit function

·         Take each input function

·         Identify Equivalence class

·         Form Test cases

·         Form Test cases for boundary values

·         From Test cases for Error Guessing

Ø       Form Unit function v/s Test cases, Cross Reference Matrix

Ø       Find the coverage
