Title

Unit Test with Google Test Activity

Overview

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

Prerequisites

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
After successfully completing this activity, the learner should be able to:
  • Configure a unit testing framework and read and interpret unit test results.
Process Skills
Practiced


Directions

Students

  • First, you will need to install Google Test on your machine. The code is provided on https://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 Google Test results that show that a test has been run and passed in command line output.

Difficulty

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

Estimated Time
to Complete

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

Environment /
Materials

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