CppUTest template

Unit testing

Goal : test separately every feature

• Test scenario (check sum() function)
• Test case (works with 2 positive numbers)
• Preconditions (C std lib works)
• Test steps (Create 2 variables, call sum(), check the result)
• Test data (a=1, b=2)
• Expected result (return value = 3)

Installing CppUTest from source code

Dependencies : autoconf, automake, lcov

sudo apt install autoconf automake lcov

./setup-cpputest.sh

If you want to force download of CppUTest, use ./setup-cpputest.sh -reinstall.

If you want to uninstall CppUTest, use ./setup-cpputest.sh -uninstall.

CppUTest using MakefileWorker

After writing configuration in MakeTests.mk, run the following commands:

Only run the tests

make tests

or

make all

Generate coverage report

make tests_coverage

Generate coverage HTML files (source files must be in the working folder)

Clean

make clean

Using CppUTest without MakefileWorker

First install cpputest package:

sudo apt install cpputest

Then complete and run this C++ example (can de done in Eclipse):

#include <CppUTest/CommandLineTestRunner.h>
#include <CppUTest/TestHarness.h>

TEST_GROUP(Group) {};

TEST(Group, Test) {};

int main(int argc, char ** argv)
{
    RUN_ALL_TESTS(argc, argv);
}
