new guy cpputest setup with eclipse

[Dainius Narsutis]

Hi everyone,

I am trying to get into TDD (I've read J Greening's book) and need to set up eclipse with cpputest. I've got an existing project and I would like to add unit tests for it. I cannot find any reasonable information for someone that is new at getting the project setup. I've got the cpputest compiled and built from github. Could anyone point me in a direction of a full tutorial/guide which can explain things in step by step?

Much appreciated.

Hello Dainius

I suggest you start with a simple working example, then keep it working
by adding your code incrementally.

Here is my starter kit:
https://github.com/jwgrenning/cpputest-starter-project. Note that the
CppUTest installation instructions is different for my starter project
than described on the cpputest.org

Here is a recipe for pulling existing code into a test harness:
https://wingman-sw.com/articles/tdd-legacy-c

Regarding eclipse, I suggest you start with the command line and the
starter project makefile, then later integrate with eclipse. You will
want to import existing makefile project into eclipse and not let
eclipse manage your makefile.

Hope that helps

James

Hi James,

Thanks for the links. I am really close to getting something working, but keep getting this error: C:\ProjectFiles\cpputest\lib\libCppUTest.a: error adding symbols: File format not recognized

Thanks.

What compiler are you using? Sounds like you might be cross compiling.
CppUTest's libraries must be built with the same compiler and target
platform.

Does CppUTest build and run its tests?

Ah that may be my problem. I followed the guide in the Readme file to build cpputest via Cygwin in Windows.

In eclipse I've created C++ project and which is using arm-none-eabi-g++.

I suggest you start from the command line getting the starter project to
compile with cygwin.

After you have stuff working in cygwin, you can optionally look at also
running your tests on target.

Thanks. I am working through your PDF found in the starter project. Step 3 is giving me an error:

Dainius Narsutis@DESKTOP-O03I4FL /cygdrive/c/Projects/cpputest-starter-project

$ make all

I know my CPPUTEST_HOME variable works too because I can type CppUTestTests into command-line and the tests run.

Hi,

I'm also stuck in step 3 getting the same error. Using cygwin on 64-bit Win 7. No prior experience with cpputest (never used c++ either, purely embedded C) so any tips on how to move on would be really appreciated.

Thanks!
