I’ll post some tips about testing during the time I learn. So if you have any comments or tips to add, feel free to comment!

Here a 10 values I submit to test a textfield:

  1. An empty value ()
  2. Zero (0)
  3. A string made of whitespace (   )
  4. String containing spaces (foo bar)
  5. Name containing special chars (♥♠♣♦)
  6. Chars with accents ( ä, ö, ü / Ä, Ö, Ü, ß, Ñ, Á, Â, Ã, À, Ç, É, Ê, Í, Ó, Ô, Õ, Ú, Ü, œ, æ, à, â, ç, é, è, ê, ë, î, ï, ô, û, ù, ü, ÿ)
  7. ‘Foreign’ chars(新 闻 – भारत)
  8. A string length between 0 and 255 chars
  9. A string length bigger than 255 chars
  10. A string length bigger than 99999 chars

Have more general test for texfield in mind?
