clearMockHistory

Class: matlab.mock.TestCase
Namespace: matlab.mock

Clear history of mock object interactions

Syntax

clearMockHistory(testCase,mock)


Description

clearMockHistory(testCase,mock) clears the history of recorded mock object interactions. The clearMockHistory method does not clear mock object behaviors. To clear both interactions and behaviors, create a new mock.

Input Arguments

testcase — Instance of test case

matlab.mock.TestCase object

Instance of the test case, specified as a matlab.mock.TestCase object.

mock — Mock to clear history

mock object

Mock to clear history of interactions from, specified as a mock object.

Examples

Clear Mock History

Construct a mock with a myMethod method.

testCase = matlab.mock.TestCase.forInteractiveUse;
[mock, behavior] = testCase.createMock("AddedMethods","myMethod");

Interact with the mock by calling the method. Then verify that the method was called.

mock.myMethod('abc');
testCase.verifyCalled(behavior.myMethod('abc'))

Verification passed.

View the interaction history.

h = testCase.getMockHistory(mock)

h = 

  SuccessfulMethodCall with properties:

       Name: "myMethod"
     Inputs: {[1×1 matlab.mock.classes.Mock]  'abc'}
    Outputs: {[]}

Interaction summary:
  myMethod([1×1 matlab.mock.classes.Mock], 'abc')

Clear the history of the recorded interaction and retest whether the method was called. The verification now fails.

testCase.clearMockHistory(mock)
testCase.verifyCalled(behavior.myMethod('abc'))

Verification failed.

    ---------------------
    Framework Diagnostic:
    ---------------------
    verifyCalled failed.
    --> Method 'myMethod' was never called.
    
    Specified method call:

        [...] = myMethod(<Mock>, 'abc')

View the interaction history again. It is empty.
