StrictExpectations (JMockit Toolkit API)

java.lang.Object
- mockit.Expectations
- - mockit.StrictExpectations

```
public abstract class StrictExpectations
extends Expectations
```
Used to record strict expectations on mocked types and their instances.
During replay, invocations matching strictly recorded expectations must occur in the same number and the same order. Any invocation that doesn't match a recorded expectation will cause an UnexpectedInvocation error to be thrown, failing the test.
Strict expectations do not allow the use of verification blocks for explicit verification. Instead, one or more strict expectation blocks are meant to fully specify all the invocations to mocked types/instances that are expected and allowed to occur from the code under test.

- Field Detail
  - $
```
protected CharSequence $
```
    An string assigned to this field will be used as a prefix for the error message shown for the current expectation if it's found to be violated.
    Inside an expectation/verification block, the assignment must follow the invocation which records/verifies the expectation; if there is no current expectation at the point the assignment appears, an IllegalStateException is thrown.
    Notice there are only two different ways in which an expectation can be violated: either an unexpected invocation occurs during replay, or a missing invocation is detected.
  - any
```
protected final Object any
```
    Matches any Object reference received by a parameter of a reference type.
    This field can only be used as the argument value at the proper parameter position in a method/constructor invocation, when recording or verifying an expectation; it cannot be used anywhere else.
    The use of this field will usually require a cast to the specific parameter type. However, if there is any other parameter for which an argument matching constraint is specified, passing the null reference instead will have the same effect.
    When the parameter to be matched is a varargs parameter of element type V, the use of any should be cast to V[].
    In invocations to non-accessible methods or constructors (for example, with Deencapsulation.invoke(Object, String, Object...)), use withAny(T) instead.

```
protected StrictExpectations(Integer numberOfIterations,
                             Object... classesOrObjectsToBePartiallyMocked)
```
    Same as StrictExpectations(Object...), but considering that the invocations inside the block will occur in a given number of iterations.
    The effect of specifying a number of iterations larger than 1 (one) is equivalent to duplicating the whole sequence of invocations in the expectation block.
    
    Parameters:
    
    numberOfIterations - the positive number of iterations for the whole sequence of invocations recorded inside the block; when not specified, 1 (one) iteration is assumed
    
    classesOrObjectsToBePartiallyMocked - one or more classes or objects whose classes are to be partially mocked
    
    See Also:
    
    StrictExpectations(), Tutorial
  - StrictExpectations
```
protected StrictExpectations(Object... classesOrObjectsToBePartiallyMocked)
```
    Same as StrictExpectations(), except that one or more classes will be partially mocked according to the expectations recorded in the expectation block.
    The classes to be partially mocked are those directly specified through their Class objects as well as those to which any given objects belong. During replay, any invocations to one of these classes or objects will execute real production code, unless a matching expectation was recorded. This mechanism, however, does not apply to native methods, which are not supported for partial mocking.
    For a given Class object, all constructors and methods can be mocked, from the specified class up to but not including java.lang.Object. For a given object, only methods can be mocked, not constructors; also, during replay, invocations to instance methods will only match expectations recorded on the given instance (or instances, if more than one was given).
    
    Parameters:
    
    classesOrObjectsToBePartiallyMocked - one or more classes or objects whose classes are to be partially mocked
    
    Throws:
    
    IllegalArgumentException - if given a class literal for an interface, an annotation, an array, a primitive/wrapper type, or a proxy class created for an interface, or if given a value/instance of such a type

- Method Detail
  - onInstance
```
protected final <T> T onInstance(T mockedInstance)
```
    Calling this method causes the expectation recorded/verified on the given mocked instance to match only those invocations that occur on the same instance, at replay time.
    By default, such instances can be different between the replay phase and the record or verify phase, even though the method or constructor invoked is the same, and the invocation arguments all match. The use of this method allows invocations to also be matched on the instance invoked.
    Typically, tests that need to match instance invocations on the mocked instances invoked will declare two or more mock fields and/or mock parameters of the exact same mocked type. These instances will then be passed to the code under test, which will invoke them during the replay phase. To avoid the need to explicitly call onInstance(Object) on each of these different instances of the same type, instance matching is implied (and automatically applied to all relevant invocations) whenever two or more mocked instances of the same type are in scope for a given test method. This property of the API makes the use of onInstance much less frequent than it might otherwise be.
    In most cases, an invocation to the given mocked instance will be made on the value returned by this method (ie, a chained invocation). However, in the situation where the tested method calls an instance method defined in a mocked super-class (possibly an overridden method called through the super keyword), it will be necessary to match on a different instance than the one used for recording invocations. To do so, this method should be given the desired instance to match, while the invocation to be recorded should be done on the available mocked instance, which must be a different one (otherwise a non-mocked method would get executed). This is valid only if the instance to be matched is assignable to the mocked type, and typically occurs when partially mocking a class hierarchy.
    
    Returns:
    
    the given mocked instance, allowing the invocation being recorded/verified to immediately follow the call to this method

  - with
```
protected final <T> T with(Delegate<? super T> objectWithDelegateMethod)
```
    Applies a custom argument matcher for a parameter in the current expectation.
    The class of the given delegate object should define a single non-private delegate method (plus any number of helper private methods). The name of the delegate method doesn't matter, but it must have a single parameter capable of receiving the relevant argument values.
    The return type of the delegate method should be boolean or void. In the first case, a return value of true will indicate a successful match for the actual invocation argument at replay time, while a return of false will fail to match the invocation. In the case of a void return type, the actual invocation argument should be validated through a suitable JUnit/TestNG assertion.
    
    Parameters:
    
    objectWithDelegateMethod - an instance of a class defining a single non-private delegate method
    
    Returns:
    
    the default primitive value corresponding to T if it's a primitive wrapper type, or null otherwise

```
protected final <T> T withAny(T arg)

    Same as withEqual(Object), but matching any argument value of the appropriate type.
    Consider using instead the "anyXyz" field appropriate to the parameter type: anyBoolean, anyByte, anyChar, anyDouble, anyFloat, anyInt, anyLong, anyShort, anyString, or any for other reference types.
    Note: when using Deencapsulation.invoke(Object, String, Object...), etc., it's valid to pass withAny(ParameterType.class) if an actual instance of the parameter type cannot be created.
    
    Parameters:
    
    arg - an arbitrary value which will match any argument value in the replay phase
    
    Returns:
    
    the input argument
    
    See Also:
    
    Tutorial
  - withArgThat
```
protected final <T> T withArgThat(org.hamcrest.Matcher<? super T> argumentMatcher)
```
    Applies a Hamcrest argument matcher for a parameter in the current expectation.
    
    Parameters:
    
    argumentMatcher - any org.hamcrest.Matcher object
    
    Returns:
    
    the value recorded inside the given Hamcrest matcher, or null if there is no such value to be found

    with(Delegate)
  - withCapture
```
protected final <T> T withCapture(List<T> valueHolderForMultipleInvocations)
```
    Captures the argument value passed into the associated expectation parameter, for each invocation that matches the expectation when the tested code is exercised. As each such value is captured, it gets added to the given list so that it can be inspected later.
    
    Parameters:
    
    valueHolderForMultipleInvocations - list into which the arguments received by matching invocations will be added
    
    Returns:
    
    the default value for type T

    Same as withEqual(Object), but checking that a numeric invocation argument in the replay phase is sufficiently close to the given value.
    
    Parameters:
    
    value - the center value for range comparison
    
    delta - the tolerance around the center value, for a range of [value - delta, value + delta]
    
    Returns:

    Same as withEqual(Object), but checking that a numeric invocation argument in the replay phase is sufficiently close to the given value.
    
    Parameters:
    
    value - the center value for range comparison

    Tutorial
  - withEqual
```
protected final <T> T withEqual(T arg)
```
    When passed as argument for an expectation, creates a new matcher that will check if the given value is equal to the corresponding argument received by a matching invocation.
    The matcher is added to the end of the list of argument matchers for the invocation being recorded/verified. It cannot be reused for a different parameter.
    Usually, this particular method should not be used. Instead, simply pass the desired argument value directly, without any matcher. Only when specifying values for a varargs method it's useful, and even then only when some other argument matcher is also used.
    
    Parameters:
    
    arg - the expected argument value
    
    Returns:
    
    the given argument
