# $callLog()

This method is used to retrieve a structure of method calls that have been made on mocked methods of the mock object. This is extermely useful when you want to assert that a certain method was called with the appropriate arguments. Great for testing method calls that save or update data to some kind of persistent storage. Also great to find out what was the state of the data of a call at certain points in time.

Each mocked method is a key in the structure that contains an array of calls. Each array element can have 0 or more arguments that are traced when methods where called with arguments. If they where made with ordered or named arguments, you will be able to know the difference. We recommend dumping out the structure to check out its composition.

```javascript
struct $callLog()
```

Examples:

```javascript
security = getMockBox().createMock("model.security");
//Call methods on it that perform something, but mock the saveUserState method, it returns void
security.$("saveUserState");

//get the call log for this method
userStateLog = security.$callLog().saveUserState;
expect( arrayLen(userStateLog) eq 0 ).toBeTrue();
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://testbox.ortusbooks.com/mocking/mockbox/verification-methods/usdcalllog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
