You can replace cl.exe with gcc or +your favorite compiler in the command above. + + +DETAILED EXAMPLE + +Here is a more detailed example. We will work through a simple +test first exercise. The goal is to create a library of string +utilities. First, lets write a function that converts a +null-terminated string to all upper case. + +Ensure that CuTest.c and CuTest.h are accessible from your C +project. Next, create a file called StrUtil.c with these +contents: + + #include "CuTest.h" + + char* StrToUpper(char* str) { + return str; + } + + void TestStrToUpper(CuTest *tc) { + char* input = strdup("hello world"); + char* actual = StrToUpper(input); + char* expected = "HELLO WORLD"; + CuAssertStrEquals(tc, expected, actual); + } + + CuSuite* StrUtilGetSuite() { + CuSuite* suite = CuSuiteNew(); + SUITE_ADD_TEST(suite, TestStrToUpper); + return suite; + } + +Create another file called AllTests.c with these contents: + + #include "CuTest.h" + + CuSuite* StrUtilGetSuite(); + + void RunAllTests(void) { + CuString *output = CuStringNew(); + CuSuite* suite = CuSuiteNew(); + + CuSuiteAddSuite(suite, StrUtilGetSuite()); + + CuSuiteRun(suite); + CuSuiteSummary(suite, output); + CuSuiteDetails(suite, output); + printf("%s\n", output->buffer); + } + + int main(void) { + RunAllTests(); + } + +Then type this on the command line: + + gcc AllTests.c CuTest.c StrUtil.c + +to compile. You can replace gcc with your favorite compiler. +CuTest should be portable enough to handle all Windows and Unix +compilers. Then to run the tests type: + + a.out + +This will print an error because we haven't implemented the +StrToUpper function correctly. We are just returning the string +without changing it to upper case. + + char* StrToUpper(char* str) { + return str; + } + +Rewrite this as follows: + + char* StrToUpper(char* str) { + char* p; + for (p = str ; *p ; ++p) *p = toupper(*p); + return str; + } + +Recompile and run the tests again. The test should pass this +time. + + +WHAT TO DO NEXT + +At this point you might want to write more tests for the +StrToUpper function. Here are some ideas: + +TestStrToUpper_EmptyString : pass in "" +TestStrToUpper_UpperCase : pass in "HELLO WORLD" +TestStrToUpper_MixedCase : pass in "HELLO world" +TestStrToUpper_Numbers : pass in "1234 hello" + +As you write each one of these tests add it to StrUtilGetSuite +function. If you don't the tests won't be run. Later as you write +other functions and write tests for them be sure to include those +in StrUtilGetSuite also. The StrUtilGetSuite function should +include all the tests in StrUtil.c + +Over time you will create another file called FunkyStuff.c +containing other functions unrelated to StrUtil. Follow the same +pattern. Create a FunkyStuffGetSuite function in FunkyStuff.c. +And add FunkyStuffGetSuite to AllTests.c. + +The framework is designed in the way it is so that it is easy to +organize a lot of tests. + +THE BIG PICTURE + +Each individual test corresponds to a CuTest. These are grouped +to form a CuSuite. CuSuites can hold CuTests or other CuSuites. +AllTests.c collects all the CuSuites in the program into a single +CuSuite which it then runs as a single CuSuite. + +The project is open source so feel free to take a peek under the +hood at the CuTest.c file to see how it works. CuTestTest.c +contains tests for CuTest.c. So CuTest tests itself. + +Since AllTests.c has a main() you will need to exclude this when +you are building your product. Here is a nicer way to do this if +you want to avoid messing with multiple builds. Remove the main() +in AllTests.c. Note that it just calls RunAllTests(). Instead +we'll call this directly from the main program. + +Now in the main() of the actual program check to see if the +command line option "--test" was passed. If it was then I call +RunAllTests() from AllTests.c. Otherwise run the real program. + +Shipping the tests with the code can be useful. If you customers +complain about a problem you can ask them to run the unit tests +and send you the output. This can help you to quickly isolate the +piece of your system that is malfunctioning in the customer's +environment. + +CuTest offers a rich set of CuAssert functions.

CuTest: C Unit Testing Framework

+ + +

Overview

+ +CuTest is a unit testing library for the C language. It can be +used to do Extreme Programming and Test-First Development in the +C language. It's a fun and cute library that will make your +programming fun and productive. + +

Benefits

+ +
    + +
  • Lower Defects. The tests ensure that your code keeps working +as you make small changes in it. + +
  • Faster Debugging. The tests tell you which subroutine is +broken. You avoid spending hours trying to figure out what's +broken. + +
  • Development Speed. You trust your old code and can keep +adding to it without worrying about bad interactions. If there is +a bad interaction the tests will catch it. + +
  • Permanent Bug Fixes. If every time a bug is reported you +write a quick test, you will guarantee that the bug never +reappears again. + +
  • Fun. As your bug count drops you will begin to enjoy +programming like you've never done before. Running the tests +every few minutes and seeing them pass feels good. + +
+ +

Features

+ +
    + +
  • Small. Consists of a single .c and .h file. + +
  • Easy to Deploy. Just drop the two files into your source +tree. + +
  • Highly Portable. Works with all major compilers on Windows +(Microsoft, Borland), Linux, Unix, PalmOS. + +
  • Open Source. You can extend it to add more functionality. +The source can be invaluable if you are trying to trace a test +failure. + +
  • Cuteness. Of all the testing frameworks CuTest has the +cutest name :-) + +
+ + +

Licensing

+ +CuTest is distributed under the zlib/libpng +license. See license.txt in the distribution for text of license. The +intent of the license is to: + +
    + +
  • Keep the license as simple as possible +
  • Encourage the use of CuTest in both free and commercial applications and libraries +
  • Keep the source code together +
  • Give credit to the CuTest contributors for their work + +
+ +If you find CuTest useful we would like to hear about it. + + +

Getting Started

+ +

For a detailed tutorial see README in the distribution. This shows you how +to organize your tests and how to autogenerate the AllTests.c file from your +source files. + +

To add unit testing to your C code the only files you need +are CuTest.c and CuTest.h. + +

CuTestTest.c and AllTests.c have been included to provide an +example of how to write unit tests and then how to aggregate them +into suites and into a single AllTests.c file. Suites allow you +to put unit tests for different parts of your code in different +files. AllTests.c combines all the suites and runs them. + +

You should not have to look inside CuTest.c. Looking in +CuTestTest.c (for example usage) should be sufficient. + +

After downloading the sources, run your compiler to create an +executable called AllTests.exe. For example, if you are using +Windows you would type: + +

+cl AllTests.c CuTest.c CuTestTest.c
+AllTests.exe
+
+ +

This will run all the unit tests associated with CuTest and +print the output on the console. + +

For more details on how to use the library look at the README file included +with the distribution. + +
