This method can help you verify that at most a maximum number of calls have been made to all mocked methods or a specific mocked method.

Boolean $atLeast(minNumberOfInvocations,[methodname])


  • maxNumberOfInvocations - The max number of calls to assert

  • methodName - The optional method name to assert the number of method calls


// 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
        // Validate them again
        if( NOT isValidUser() ){
            log.error("user from cookie invalid, aborting");

// Now the test
it( "can verify a user", function(){
    security = createMock("model.security").$("isValidUser",false);

    // Asserts that isValidUser() has been called at most 1 times
    expect( security.$atMost(1,"isValidUser") ).toBeFalse();
