$once()

This method can help you verify that only ONE mocked method call has been made on the entire mock or a specific mocked method. Useful alias!
Boolean $once([methodname])
Parameters:
methodName - The optional method name to assert the number of method calls
Examples:
// let's say we have a service that verifies user credentials
// and if not valid, then tries to check if the user can be inflated from a cookie
// and then verified again
function verifyUser(){
​
    if( isValidUser() ){
        log.info("user is valid, doing valid operations");
    }
​
    // check if user cookie exists
    if( isUserCookieValid() ){
        // inflate credentials
        inflateUserFromCookie();
        // Validate them again
        if( NOT isValidUser() ){
            log.error("user from cookie invalid, aborting");
        }
    }
}
​
// Now the test
it( "can verify a user", function(){
    security = getMockBox().createMock("model.security").$("isValidUser",false);
    security.storeUserCookie("valid");
    security.verifyUser();
​
    expect( security.$once("isValidUser") ).toBeTrue();
});
