QUESTION
I'm working on a templated class, and given an incoming type T the template needs to map to a "safe" const reference. (This is essentially to avoid handing the ability to mutate to a wrapped function when it's called; see here for the real code).
The original author wrote something equivalent to this:
...ANSWER
Answered 2022-Apr-11 at 03:59Which part of the standard says that the const is "lost" in an expression like const T& for a templated T expanding to an rvalue reference?
From dcl.ref/p6:
If a typedef-name ([dcl.typedef], [temp.param]) or a decltype-specifier ([dcl.type.decltype]) denotes a type TR that is a reference to a type T, an attempt to create the type lvalue reference to cv
TRcreates the type lvalue reference toT, while an attempt to create the type rvalue reference to cv TR creates the typeTR.
The quote probably explains the behavior you're seeing.
QUESTION
I am not sure if what I am trying to do is possible, but I have a hard time with the compiler trying to mock a method which contains a templated reference parameter.

Answered 2022-Mar-16 at 19:06Somehow you need to tell your TestService class to use the mock object instead of the real object.
Currently you instantiate the DatabaseClient in create():

QUESTION
Using the googletest framework I want to write my own main function. Basically some custom initialization step needs to happen before RUN_ALL_TESTS is called. I'd like to skip this step, if the command line parameters for googletest indicate, no tests should be run (e.g. if --gtest_list_tests is passed).
Is it possible to retrieve this kind of information from the test framework without the need to parse the parameters myself?
What I'd like to accomplish:

QUESTION
I have been given a list of 25 tests and a order to run them in that is supposedly causing a failure in the last test. Unfortunately the tool that was used to find this failure does not save the seed that was used by GoogleTests shuffle to trigger this order.
So I can of course just run the tests with shuffle and repeat a huge number of times until this order is triggered, but there is quite a lot of permutations to work through. As far as I can tell there isn't a way to just say "Hey run these tests in this order" with GoogleTest aside from knowing the seed to trigger the order.
I'm hoping there might be a way to find that seed without actually running the tests - ideally something that could be given the desired order and output the seed, but really just something that given the gtest_filter value just dumps out massive amounts of potential test orders and the seeds that trigger them would be fine.
Is there any options out there, or I'm I just running with shuffle until I get it?
...ANSWER
Answered 2022-Feb-01 at 22:02There is no such option to specify the order of the tests.
However, By default (i.e. if --gtest_shuffle is not enabled), they run in the declaration order.
I can think of three ways of achieving what you want:
Use your favorite scripting language (e.g. bash, python, nodejs, etc) and regular expressions to modify the original order of the tests to your desired order and create a new test file which then you run without
--gtest_shuffle.Hack into Google test's source code. You can modify the shuffle function to shuffle the code in the order that you want.
Look into Registering tests programmatically. I think you might be able to register your tests one by one in the order that you want, and I think Googletest will observe that order. But this also requires processing your original test file.
Obviously, none of these methods are ideal, but they might work for a one-off experiment to find the order that you want.

I was reading partially ordered calls for googletest here and I understoond how their example works. So we can use:

Answered 2021-Dec-18 at 19:03You can use After method to expect some call after certain other call(s). https://google.github.io/googletest/reference/mocking.html#EXPECT_CALL.After

QUESTION
Google recommends to use the text fixture constructor/destructor when possible instead of SetUp()/TearDown() (https://google.github.io/googletest/faq.html#CtorVsSetUp). Assuming I do it this way, what is the use of even using a test fixture? How are the following different, and what is the advantage of the first?

Answered 2021-Nov-10 at 11:06The advantages are visible when there are more than one TEST/TEST_F. Compare:
