Transwiki:Common Test Cases

This page was transwikied from another project and needs to be adopted.
This page needs to be moved to the main namespace, either as the main page of a book, or as a chapter of another book. After moving, please remove {{Tw-adopt}} from this page.

The purpose of this page is to help suggest some possible test cases you should be running for different types of things one might test.

Purpose[edit source]

The purpose of this page is to get QA engineers thinking out of the box when it comes to testing different permutations of data. This site does not tell you how the system you are testing should react to this data, but is just a suggestion of the type of data you should try to use for testing. Please feel free to add your own permutations to this site.

  • Trailing Spaces ("123.08 ")
  • Spaces in the middle ("123 456.85")

  • Characters that represent Floating or Doubles
    • Float (10.00F, 10.00f)
    • Double (10.00D, 10.00d)

Objects[edit source]

  • Null
  • Valid Object
  • Object that can be cast to the correct type of object
    • Example: API takes object Cat, I should pass in object Animal
      • Foo ([CAT]Animal)
    • Example: Api takes object Animal, I should pass in object Cat since it inherited from Animal
      • Foo2 (Cat)

Dates[edit source]

  • Test All Months
  • Test all days of the week
  • Test the first date of each month
  • Test the last day of each month
  • Test days that never exist
    • February 30
  • Leap Year
    • February 29
  • Formatting
    • YY-MM-DD
    • YYYY-MM-DD
    • DD-MM-YY
    • MM-DD-YYYY
    • MM/DD/YY
    • Many others, see your languages date formatting options
    • Note: Different Databases have different formatting for dates
  • Leading/Trailing Zeros
    • 08-01-07
    • 10-30-2010
  • Numerical representation of Months
    • Try each # (1-12)
    • Try 0
    • Try 13
  • Gotchas
    • In Java, the Month is zero-indexed. This means if you pass in 5 (May), it could be interpreted as 6 (June). This is particarly important for dates that are going to be compared.
