Overview

This class is abstract.

Subclass and implement #matches? and #mocha_inspect to define a custom matcher. Also add a suitably named instance method to Mocha::ParameterMatchers to build an instance of the new matcher c.f. #equals.

Instance Method Details

#&(matcher) ⇒ AllOf

A shorthand way of combining two matchers when both must match.

Returns a new AllOf parameter matcher combining two matchers using a logical AND.

This shorthand will not work with an implicit equals match. Instead, an explicit Equals matcher should be used.

Examples:

Alternative ways to combine matchers with a logical AND.

object = mock()
object.expects(:run).with(all_of(has_key(:foo), has_key(:bar)))
object.run(:foo => 'foovalue', :bar => 'barvalue')

# is exactly equivalent to

object.expects(:run).with(has_key(:foo) & has_key(:bar))
object.run(:foo => 'foovalue', :bar => 'barvalue)

#|(matcher) ⇒ AnyOf

A shorthand way of combining two matchers when at least one must match.

Returns a new AnyOf parameter matcher combining two matchers using a logical OR.

This shorthand will not work with an implicit equals match. Instead, an explicit Equals matcher should be used.

Examples:

Alternative ways to combine matchers with a logical OR.

object = mock()
object.expects(:run).with(any_of(has_key(:foo), has_key(:bar)))
object.run(:foo => 'foovalue')

# is exactly equivalent to

object.expects(:run).with(has_key(:foo) | has_key(:bar))
object.run(:foo => 'foovalue')

Using an explicit Equals matcher in combination with #|.

object.expects(:run).with(equals(1) | equals(2))
object.run(1) # passes
object.run(2) # passes
object.run(3) # fails
