How to configure and setup google test framework in linux

Question

I'm a newbie to g test and Here is what I am trying to do (On a Linux server from console): 1) Create a small project in C++ ( with a header file containing a function prototype, a cpp file with a function in it and another cpp file with main calling the function already defined in the header file ) 2) Configure g test to write unit tests and test the function created in the step 1 3) Create another small project with a couple of unit tests (different scenarios to test the function created under the project in step 1)

Can anyone please tell how to configure g test and the projects created with an example?

Thanks in advance

Answer 1

1. First of all, get the most updated version of GoogleTest from the Subversion repository (you need Subversion installed):

   cd ~
   
   svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only
   

2. Then, build the library (you need cmake installed):

   mv googletest-read-only googletest
   
   mkdir googletest/lib
   
   cd googletest/lib
   
   cmake ..
   
   make
   

3. At this point:

   • compiled libraries are in the ~/googletest/lib directory
   • include files are in the ~/googletest/include directory

To use googletest:

1. Include the header in your files:

   #include "gtest/gtest.h"
   

2. Export the library path:

   export GOOGLETESTDIR=~/googletest
   

3. Compile with

   g++ ... -I$GOOGLETESTDIR/include -L$GOOGLETESTDIR/lib -lgtest -lpthread
