QUESTION

Why is the const lost in an expression like `const T&` where T is an rvalue reference?

Asked 2022-Apr-11 at 03:59

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

Which 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 TR creates the type lvalue reference to T, while an attempt to create the type rvalue reference to cv TR creates the type TR.

The quote probably explains the behavior you're seeing.

Somehow 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

Is there a way to detect command line arguments not running tests?

Asked 2022-Feb-16 at 01:12

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

Is it possible to find the seed for GoogleTest to run a specific order if the order is known?

Asked 2022-Feb-01 at 22:02

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 22:02

There 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.

What is the use of a test fixture in google test?

Asked 2021-Nov-10 at 11:06

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?

Install googletest

To build Google Test and your tests that use it, you need to tell your build system where to find its headers and source files. The exact way to do it depends on which build system you use, and is usually straightforward.
Suppose you put Google Test in directory ${GTEST_DIR}. To build it, create a library build target (or a project as called by Visual Studio and Xcode) to compile.
Before settling on CMake, we have been providing hand-maintained build projects/scripts for Visual Studio, Xcode, and Autotools. While we continue to provide them for convenience, they are not actively maintained any more. We highly recommend that you follow the instructions in the previous two sections to integrate Google Test with your existing build system.
