Test case examples for validation with equivalence classes and boundary values.

Examples of test cases using equivalence classes and boundary values:

1. Validation of the "Age" field (acceptable range 18-65):

   • Equivalence classes:
     • Valid: 18-65
     • Invalid: less than 18
     • Invalid: greater than 65
   • Boundary values:
     • 17 (lower boundary -1)
     • 18 (lower boundary)
     • 65 (upper boundary)
     • 66 (upper boundary +1)

2. Validation of the "Password" field (minimum 8 characters):

   • Equivalence classes:
     • Valid: length >= 8
     • Invalid: length < 8
   • Boundary values:
     • 7 characters
     • 8 characters

3. Validation of the "Email" field:

   • Equivalence classes:
     • Valid: correct email format
     • Invalid: missing '@'
     • Invalid: missing domain

This approach helps cover different scenarios and identify errors at the boundaries of acceptable values.
