New with CppUTest and need help with my first steps

[Jorge Sola]

Dear all,

I am new to Test Driven Development and I am following the book "Test driven development for embedded C". Thus, I downloaded CppUTest and Cygwin, and built the CppUTest as it says in the instructions. Actually, the example tests are run and everything seems ok.

My question comes now: what do I have to do to run my own tests? Lets assume that I already have my Module.c, Module.h and ModuleTest.cpp, ok. What do I have to do to compile it and run the test? Because right now, I am really really lost, and everything I see is like Chinese for me.

Could anyone help me with that?

Thank you and best regards.

Hi Jorge

I replied to you at progprog too. So I'll put my reply here too.

I suggest you start with CppUTest and follow the instructions in my
[starter project on github](https://github.com/jwgrenning/tddec-code).
You can also fond that [book
examples](https://github.com/jwgrenning/tddec-code) on github.

In case you are interested, I will be hosting a [TDD for Embedded C web
delivered training
class](https://wingman-sw.com/training/remote-delivered-tdd) in early
August. It would be a good way to get a jump start on TDD.

Hope that helps.

thanks for buying and reading my book!

James

Hello James,

Thank you very much for your answer. I followed your suggestions and downloaded the code from both links (starter project and the 'new version' of the book code). The first thing I did was to try to compile the t0 of the book code, and this is what I get:

/cygdrive/g/users/j/jsolamer/desktop/tddec-code-master/tddec- code-master/code-t0

$ make

compiling AllTests.cpp

Do you know how to get rid of these errors?

Thank you and best regards,

Jorge.

Hello again,

After spending some more time trying to make this work, I managed to the following:

- In order to get rid of the error on my previous message, I went to MemoryLeakDetectorNewMacros.h and commented out the corresponding lines with the  "void operator delete[] (void* mem, size_t size) UT_NOTHROW".

- After doing so, I got rid of the error, but I got a new error message:

$ make

compiling AllTests.cpp

compiling LightSchedulerRandomizeTest.cpp

compiling LightSchedulerTest.cpp

compiling RandomMinuteTest.cpp

compiling LightControllerTestSpy.cpp

compiling FakeTimeServiceTest.cpp

compiling LightControllerSpy.c

In file included from G:/Users/j/jsolamer/Desktop/cpputest-3.8/cpputest-3.8/include /CppUTest/MemoryLeakDetectorMallocMacros.h:12:0,

make: *** [G:/Users/j/jsolamer/Desktop/cpputest-3.8/cpputest-3.8/build/MakefileWork er.mk:509: objs/mocks/LightControllerSpy.o] Error 1

- In order to get rid of that, and after googling a while, I added this line to the makefile: CPPUTEST_CFLAGS += -std=c99

- After doing so, I got rid of that error, but I got the following error:

$ make
compiling LightControllerSpy.c
compiling FakeRandomMinute.c
compiling FakeTimeService.c

make: *** No rule to make target 'G:/Users/j/jsolamer/Desktop/cpputest-3.8/cpputest-3.8/lib/libCpp UTest.a', needed by 't0_tests'. Stop.

I got rid of the error by copying the /lib folder from the /cpputest-3.8/cpputest_build to the /cpputest-3.8 folder (which is the main cpputest folder). And I managed to compile the code t0, showing the following:

$ make
Linking t0_tests
Running t0_tests
.............................................
OK (45 tests, 45 ran, 407 checks, 0 ignored, 0 filtered out, 2 ms)

I did the same for the project t1, however, I get one more error message:

Some tip about that error?

 

[James Grenning]

Try removing this from the makefile

CPPUTEST_CFLAGS += -std=c89

Hi Jorge,

Did you try building CppUtest with “configure” and then “make” or just tried using the MakefileHelper?

Thanks!

Bas

I have exactly this error using 64 bit cygwin on 64 bit windows 7.

After adding the following to cygwin (adding again for Perl)

  autoreconf

  autoconf

  libtool

  automake

  Perl

Then using 

   autoreconf .. -i

   ../configure

   make

   make check-coverage

which were successful,

Then changing to the project folders for tddec, with CPUTEST_HOME correct

  make everything

Gives the following results

$ make everything

make -i -C t0

 typedef long long cpputest_longlong;

(and so on)

I hope this is useful extra information.

Jorge, 

   I found that by editing book/code/t1/Makefile and removing CPPUTEST_WARNINGFLAGS += -Werror it built (with warning) and passed all checks. I'm using Windows 10 vers 1903 with MSYS2 and gcc 9.

best belated wishes

Keith
