Type Parameters

  • T


  • expected
    Type: T

    The first generic type data to compare. This is the generic type data the unit test expects.

  • actual
    Type: T

    The second generic type data to compare. This is the generic type data the unit test produced.

  • message
    Type: String

    A message to display if the assertion fails. This message can be seen in the unit test results.

  • parameters
    Type: array<Object[]

    An array of parameters to use when formatting message.


Exception Condition

expected is not equal to actual.


Different numeric types are treated as equal if the logical values are equal. For example, 42L is equal to 42.

T is the type of values to compare.
