object TypeCheckedTripleEquals extends TypeCheckedTripleEquals

Companion object to trait TypeCheckedTripleEquals that facilitates the importing of TypeCheckedTripleEquals members as an alternative to mixing it in. One use case is to import TypeCheckedTripleEquals members so you can use them in the Scala interpreter:

$ scala -classpath scalatest.jar

Type Members

  1. class CheckingEqualizer[L] extends AnyRef

    Class used via an implicit conversion to enable two objects to be compared with === and !== with a Boolean result and an enforced type constraint between two object types.

    Class used via an implicit conversion to enable two objects to be compared with === and !== with a Boolean result and an enforced type constraint between two object types. For example:

    assert(a === b)
assert(c !== d)

    You can also check numeric values against another with a tolerance. Here are some examples:

    assert(a === (2.0 +- 0.1))
assert(c !== (2.0 +- 0.1))
