How can I effectively test a C++ library?

To effectively test a C++ library, you should consider using a testing framework like Google Test or Catch2. These frameworks provide tools for writing and running tests.

What are some best practices for writing tests?

Some best practices include writing clear and concise test cases, using descriptive names for your tests, and ensuring that each test is independent.

How do I set up Google Test in my project?

You can set up Google Test by including it as a submodule in your project, or by installing it via a package manager like vcpkg. Then, link it to your project and start writing tests.

Can you give me an example of a simple test case?

Sure! Here's a simple test case using Google Test:

#include <gtest/gtest.h>

TEST(MyTestSuite, MyTestCase) {
    EXPECT_EQ(1 + 1, 2);
}

This tests that 1 + 1 equals 2.
