Equivalence partitioning

Meaning in software engineering, with examples

nounCommon term

In software engineering, equivalence partitioning means: Dividing possible inputs into groups expected to behave alike, then testing representative values from those groups.

In Turkish: eşdeğerlik bölümlendirmesi

How it is used

Used to reduce redundant test cases. The groups are assumptions about behavior and should follow requirements.

Example sentences

  1. Our equivalence partitioning separated valid dates from malformed and out-of-range inputs.

    Different failure causes form different groups rather than one universal invalid category.

  2. We revised the equivalence partitioning after learning that guest accounts have different limits.

    A newly discovered rule means inputs previously grouped together need separate treatment.

Common collocations

  • use equivalence partitioning
  • equivalence partitioning technique
  • test caseOne specific situation you check, with set inputs, steps and an expected result, for example 'logging in with a wrong password shows an error'.
  • requirementSomething the software must do, or a condition it must meet, as agreed with users, clients or the product team.
