Mocking Async Calls [duplicate]

• Expecting googlemock calls from another thread 2 answers

I am writing tests for a project using Google Mock. There are async calls and i am having a hard time checking the sequence of function calls. Here is an example run:

1. service::start


2. manager::start


3. manager::apples //first thread


4. manager::egg //second thread


5. service::doSomething


6. apples::start //async


7. apples::create_apples //async


8. eggs::start //async


9. eggs::create_eggs //async


10. service::doAnother


11. eggs::pack_eggs //async


12. apples::pack_apples //async

I checked google mock CheatSheet: http://ift.tt/1ybj1OV But i can't get it to work as I wanted to.

sequence_check_mock obj;
mock_obj_ = &obj;
{
    Sequence s1, s2;
    EXPECT_CALL( *mock_obj_, service_start() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, manager_start() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, manager_apples() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, manager_eggs() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, service_doSomething() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, apples_start() ).InSequence( s1 );
    EXPECT_CALL( *mock_obj_, apples_create_apples() ).InSequence( s1 );
    EXPECT_CALL( *mock_obj_, eggs_start() ).InSequence( s2 );
    EXPECT_CALL( *mock_obj_, eggs_create_eggs() ).InSequence( s2 ); 
    EXPECT_CALL( *mock_obj_, service_doAnother() ).InSequence( s1, s2 );
    EXPECT_CALL( *mock_obj_, eggs_pack_eggs() ).InSequence( s2 );
    EXPECT_CALL( *mock_obj_, apples_pack_apples() ).InSequence( s1 );
}

The checking is ok until service_doAnother. But sometimes, service_doAnother is called after eggs_pack_eggs or apples_pack_apples so the test would fail. Since in the sequence, it is expected that doAnother should be called before.

10. eggs::pack_eggs //async


11. apples::pack_apples //async


12. service::doAnother
