Types

Every generated mock implementation adopts Mock protocol. It defines base Mock structure and features.

Every mock, that stubs static methods, should adopt StaticMock protocol. It defines base StaticMock structure and features.

Parameter wraps method attribute, allowing to make a difference between explicit value, expressed by .value case and wildcard value, expressed by .any case.

Whole idea is to be able to test and specify behaviours, in both generic and explicit way (and any mix of these two). Every test method matches mock methods in signature, but changes attributes types to Parameter.

That allows pattern like matching between two Parameter values:

• .any is equal to every other parameter. (!!! actual case name is ._, but it is advised to use .any)
• .value(p1) is equal to .value(p2) only, when p1 == p2

Important! Comparing parameters, where ValueType is not Equatable will result in fatalError, unless you register comparator for its ValueType in Matcher instance used (typically Matcher.default)

• any: represents and matches any parameter value
• value: represents explicit parameter value

Matcher is container class, responsible for storing and resolving comparators for given types.

Allows matching count, verifying whether given count is right or not

Count enum. Use it for all Verify features, when checking how many times something happened.

There are three ways of using it:

1. Explicit literal - you can pass 0, 1, 2 … to verify exact number
2. Using predefined .custom, to specify custom matching rule.
3. Using one of predefined rules, for example:
   • .atLeastOnce
   • .exactly(1)
   • .from(2, to: 4)
   • .less(than: 2)
   • .lessOrEqual(to: 1)
   • .more(than: 2)
   • .moreOrEqual(to: 3)
   • .never
