Troubleshooting running unit tests #92

Closed narner closed 7 years ago

narner commented 7 years ago

Hey Nick,

I'm attempting to run the GRT unit tests. Right now, I'm encountering three problems when building the GRT unit tests (using gcc):

  1. When building tests, I would get an error saying that #include <GRT.h> could not be found. I fixed this by changing the path to: #include "../../GRT/GRT.h"
  2. After the above error was resolved, I got an error stating that #include "gtest/gtest.h" could not be found. I resolved that by changing the path to #include "../../third_party/gtest/googletest/include/gtest/gtest.h"
  3. ...Once that was resolved, I'm now getting an error of gtest/internal/gtest-internal.h' file not found.

I've built googlemock and googletest inside the third_party/gtest folder, following the directions here, so I don't think the problem is with how those two frameworks are being built.

How are you running the unit tests? Are you using cmake to generate the main library and the unit tests?

If so, cmake will automatically call a script that builds and links against the unit test library (gtest).

This is how I run the unit tests (and build the library):

cd grt_parent_directory      #cd to the grt parent directory
cd build                     #cd to the main build directory
mkdir tmp                    #if it doesn't already exist, make a temporary directory
cd tmp                       #cd to the temporary directory
cmake ..                     #run the cmake script, pointing to the CMakeLists.txt file that lives one directory above (..), this will configure the build scripts for your machine
make -j4                     #build the library, running 4 jobs at once (a.k.a. use 4 threads/processors if you have them)
make test                    #run the unit tests

Ah, I had been trying to run each test individually, so was doing:

g++ ./ANBCTest.cpp

The commands you used worked for me also, thank you.
