asserts is a simple library that offers assertion expressions that can be used with Google Test in order to write more readable code.

To use the library, the Google Test library and the PEGTL library are required.

To run the test cases, you will need Java to run the Gradle build system. Gradle itself isn't needed, because the wrapper script should download the appropriate version of it automatically. You will also need the mtrace_gtest library. You can set the path to the libgtest.a, libmtrace_gtest.a and libmtrace_gtest_main.a libraries, and to the PEGTL headers in the build.gradle` file.

The library is only made of header files, so compiling it separately is not necessary.

You can run all of the built-in tests running the command

./gradlew test

To use the library, all you have to do is include the asserts.hpp header file.

#include <tuple>

#include <gtest/gtest.h>

#include "asserts.hpp"

TEST(TestCase, firstTest) {
    int value = 3;

    assertThat(value).isEqualTo(3);
    assertThat(value).isLessThan(10);
}

TEST(TestCase, secondTest) {
    AssertThat<std::tuple<int, char> >::isConstructible(With<int, char>());
    AssertThat<std::tuple<> >::isConstructible(WithoutParameters());
}

TEST(TestCase, thirdTest) {
    int value = 3;
    int& reference = value;

    assertThat(reference).isAtSameAddressAs(value);
}

Feel free to send feedback, questions, suggestions, fixes, bug reports, or anything else you think can help this project.

If you provide code, my only request is to also provide test cases of what is being done and/or what bugs were fixed (ie. a test that fails without the new code and passes with the new code).

Personally, I develop using TDD, so I would recommend that. However, feel free to add tests after development if you prefer. I might reorder the commits to push the tests first though. Also keep the tests small. I'd rather have a million small and focused tests than one that does the same thing but makes it hard to isolate future problems.
