After failing to get coverage with-cmake I set up a minimalistic project to see if I can get coverage working that way. It's derived from using-gtest-without-cmake

It has a src folder with a header and source file in it. QuickMaths.hpp :

I am new to googletest/googlemock and I have following questions:

First question: I have this DatabaseClient class which has a method query_items which I want to mock. I`m unable to find the syntax to do it. Here is my attempt:

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:

Issue

I need a help in fixing my unit test issue with gtest 1.10.0 version. When I tried to unit test involving a function that accepts std::experimental::any argument, exception is thrown and unit test terminated.

Steps to reproduce the issue

Snippet of unit tests covering my test scenario available under https://godbolt.org/z/Y7dvEsaPf In TestBoth testcase, if EXPECT_CALL and actual function calls are adjacently provided, exception is not thrown and test case execute successfully. But in my actual project code, my test function has call to send_data() function with both these data types.

Tool and operating system versions gtest version is 1.10.0 Ubuntu Linux 20.04

Compiler version

g++ (Ubuntu 10.3.0-1ubuntu1~20.04) 10.3.0 C++14

Build system

cmake version 3.20.5

Additional context

Help needed or please direct to where I can get this query asked and get resolved.

I have a module written in C. In which I have API defined as follow.

new keyword in C++ will throw an exception if insufficient memory but below code trying to return "NO_MEMORY" when new failed. This is bad because it will raise std::bad_alloc exception .

I am writing a unit test(gtest). How to create a scenario to catch this problem.

I have a test suite setup that takes some time to run. (Open a serial port initialize communication with a board, etc).

I would like to run a test in a loop, but without running this setups and cleanups every time because they are not needed, and only consume time.

The default behavior of TestSuiteSetup is to be executed once and then allow any number of tests from that suite to run. Running multiple tests in a suite or repeating one test are actually the same use case, but it seems not to be supported by -repeat. (I would expect it to be possible to combine the flag with an option like: -run_setup_only_once)

Is this possible in gtest? Or is there another way to achieve this?

I want to defer the execution of a packaged task in a loop.

My main question is about a specific gmock error but to provide some background. I have been working on a larger project where I have different implementations of the same interface. I want to be able to instantiate a class using the interface and choose which interface implementation it has to use (when creating the class instance). The interface is not shared and each instance of the interface is only used by one class instance. In order to do this I use dependency injection and I store the interface instance in a unique_ptr. This works properly and gives me the desired behavior. To unit test some the class I used gmock to mock the interface and then injected the mocked interface into my class under test. To my surprise gmock informed me that I had a memory leak which I do not understand. A simplified piece of code produces the same error:
