Google Test Installation Guide for C++ in Windows ( for Visual Studio Code)

Hey, budding c++ coders out there! On your way to becoming a fleshed out developer? I presume you have installed a code editor of your choice, installed compilers, debuggers and all the necessary libraries. But you are missing one mostly overlooked component by beginners, the testing tool.

We will see :

1. What is Google C++ testing framework?

2. Why Google test?

3. Installation steps

4. Sample program

1. What is Google C++ testing framework?

Google Test is a unit testing library for the C++ programming language, based on the xUnit architecture.

Or simply put, it makes your C++ testing easy and efficient. Basically, you’ll write a test program, containing many test cases and will check it against your program after compiling Google test into a library.

The test function is made up of macros, which are more like functions whose parameters are the values inputted to test the function. These macros are assertions which will return True or False according to the assertion type.

When the Watch Window in Visual Studio Doesn't Update

While debugging in Visual Studio, you may notice, when you check some value in the Watch window, one of two icons beside your data. You may get one or the other of a circle with two wavy lines inside of it or the standard refresh icon of two curved arrows chasing each other. Either icon indicates that the data being displayed in the Watch window isn’t up to date.

There are two reasons for these icons appearing: Either there’s been a problem in fetching the data (e.g. a timeout) or Visual Studio is concerned that evaluating the expression may result in some side-effects that will make debugging more difficult for you.

It’s lovely that you get that warning but, if you’ve noticed the icons then it’s probably because you’re checking the value and, if you’re checking the value then it’s probably because you need that value. Clicking the icon will force Visual Studio to make another attempt at giving you the latest version of the data you want.

If you can’t get the data you want (or if it turns out that Visual Studio was right and re-evaluating the expression really did make your life more difficult) then your best option is to set a breakpoint a line or two earlier and re-run your test.

A Better Way to Test for Exceptions in Visual Studio

I’ve always argued that the only easier way to test your code than using Visual Studio Test is to not test at all. But that doesn’t mean that I think Visual Studio Test is perfect.

For example, the ExpectedException attribute, when placed on a test method, lets you check to make sure that your code throws the appropriate exception when something goes horribly wrong. The problem with ExpectedException is that it applies to the whole test method, not just the “code under test.” This means that if your test or production code throws that exception anywhere at all, the ExpectedException attribute will tell you that your test has passed. Unfortunately, that exception may or may not have been thrown where you actually expected it to be thrown. That’s not quite what you want to test for.

You have a better alternatives: the Assert object’s ThrowsException and ThrowsExceptionAsync methods. With either of those methods, you specify the exception you expect to get from your method and then pass the code you want to test (as a lambda expression) to the method.

This example checks to see if the GetCustomer method throws a NullReferenceException when the GetCustomer method is called with an empty string:

Customer cust;
Assert.ThrowsException<NullReferenceException>(() => cust = CustomerRepository.GetCustomer(""));

This test will now pass if (and only if) this call to the GetCustomer method throws a NullReferenceException. If any other code in my test method throws that exception (or if my code throws any other kind of exception), my test will be flagged as failed. And that’s exactly what I want.

[Guest post] Learn C# with Visual Studio, Visual Studio for Mac, and Unity

UPDATE: The book giveaway challenge is complete. We will be announcing winners on the Visual Studio blog within the next week. Thank you for your submissions!

Visual Studio is an amazing development tool. But Visual Studio and Visual Studio for Mac are more than just intuitive, state-of-the-art development environments. They’re also remarkably powerful learning and exploration tools, with features to help you create and understand your code. I love teaching and learning about C## with Visual Studio. That’s why my co-author, Jenny Greene, and I put Visual Studio and Visual Studio for Mac right at the center of our latest book, _Head First C# _(4th edition), published by O’Reilly Media. _Head First C# _incorporates Visual Studio directly in the learning. combining Visual Studio with the unique and innovative “brain-friendly” Head First approach to teaching helps us make learning C## easier and more fun for our readers.
