Title

Unit Test with GoogleTest Activity

Overview

Participants install the Google Test library and run an existing C++ project to see individual test results and confirm successful installation.

Prerequisite Knowledge

Have set up a development environment that will compile C++. Configurations differ slightly from one operating system to another, but should work on most.

Learning Objectives

Participant should be able to learn how to configure a unit testing framework and read and interpret unit test results.

Directions:

Students:

  • First, you will need to install Google Test on your machine. The code is provided on GitHub.com/google/googletest
  • I suggest placing Google Test in a location where other source libraries are placed, such as /usr/local/include
  • Next, go to a different directory (such as one you use to organize your files for this course, or a folder where you store your own code). Clone this cpp-gtest repository.
  • Once cloned, edit Makefile find this line: GTEST_DIR = /usr/local/include/gtest and change it to the directory you placed Google Test. Provide the entire path to the directory in Google Test that has the following folders/files:
    internal
    gtest.h
    gtest-typed-test.h
    gtest-test-part.h
    (and more .h files...)
  • Once you've edited the file, save it and run the command Make
  • Next, run the command ./RandoTest
  • The output should show that one test has been run (and passed).
  • Take a screenshot of this output and submit the image for this assignment

Deliverables:

A screen shot of the automated test results.


Notes for Instructors

Assessment:

Students should have a screen shot of GoogleTest results that show that a test has been run and passed in command line output.

Level of Difficulty

Configuring the development environment with the GoogleTest library takes intermediate expertise of operating system command-line navigation

Estimated Time to Completion

Download and configuration may take 5 to 20 minutes, depending on the students' operating systems and existing development environment.

Materials/Environment

Need a development environment with support for Makefile and C++ compilation (g++ recommended)
