HOW TO USE
|
||||
|
||||
You can use CuTest to create unit tests to drive your development
|
||||
in the style of Extreme Programming. You can also add unit tests to
|
||||
existing code to ensure that it works as you suspect.
|
||||
|
||||
Your unit tests are an investment. They let you to change your
|
||||
code and add new features confidently without worrying about
|
||||
accidentally breaking earlier features.
|
||||
|
||||
|
||||
LICENSING
|
||||
|
||||
For details on licensing see license.txt.
|
||||
|
||||
|
||||
GETTING STARTED
|
||||
|
||||
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 group tests into logical sets. AllTests.c combines all the
|
||||
suites and runs them.
|
||||
|
||||
You should not have to look inside CuTest.c. Looking in
|
||||
CuTestTest.c and AllTests.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 with the cl.exe compiler you would type:
|
||||
|
||||
cl.exe 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. 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. Here is a list:
|
||||
|
||||
void CuAssert(CuTest* tc, char* message, int condition);
|
||||
void CuAssertTrue(CuTest* tc, int condition);
|
||||
void CuAssertStrEquals(CuTest* tc, char* expected, char* actual);
|
||||
void CuAssertIntEquals(CuTest* tc, int expected, int actual);
|
||||
void CuAssertPtrEquals(CuTest* tc, void* expected, void* actual);
|
||||
void CuAssertPtrNotNull(CuTest* tc, void* pointer);
|
||||
|
||||
The project is open source and so you can add other more powerful
|
||||
asserts to make your tests easier to write and more concise.
|
||||
Please feel free to send me changes you make so that I can
|
||||
incorporate them into future releases.

|
||||
AUTOMATING TEST SUITE GENERATION
|
||||
|
||||
make-tests.sh will grep through all the .c files in the current
|
||||
directory and generate the code to run all the tests contained in
|
||||
them. Using this script you don't have to worry about writing
|
||||
AllTests.c or dealing with any of the other suite code.

<H1>CuTest: C Unit Testing Framework</H1>
|
||||
|
||||
|
||||
<h2>Overview</h2>
|
||||
|
||||
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.
|
||||
|
||||
<h2>Benefits</h2>
|
||||
|
||||
<ul>
|
||||
|
||||
<li> Lower Defects. The tests ensure that your code keeps working
|
||||
as you make small changes in it.
|
||||
|
||||
<li> Faster Debugging. The tests tell you which subroutine is
|
||||
broken. You avoid spending hours trying to figure out what's
|
||||
broken.
|
||||
|
||||
<li> 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.
|
||||
|
||||
<li> Permanent Bug Fixes. If every time a bug is reported you
|
||||
write a quick test, you will guarantee that the bug never
|
||||
reappears again.
|
||||
|
||||
<li> 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.
|
||||
|
||||
</ul>
|
||||
|
||||
<h2> Features </h2>
|
||||
|
||||
<ul>
|
||||
|
||||
<li> Small. Consists of a single .c and .h file.
|
||||
|
||||
<li> Easy to Deploy. Just drop the two files into your source
|
||||
tree.
|
||||
|
||||
<li> Highly Portable. Works with all major compilers on Windows
|
||||
(Microsoft, Borland), Linux, Unix, PalmOS.
|
||||
|
||||
<li> Open Source. You can extend it to add more functionality.
|
||||
The source can be invaluable if you are trying to trace a test
|
||||
failure.
|
||||
|
||||
<li> Cuteness. Of all the testing frameworks CuTest has the
|
||||
cutest name :-)
|
||||
|
||||
</ul>
|
||||
|
||||
|
||||
<h2>Licensing</h2>
|
||||
|
||||
CuTest is distributed under the <a
|
||||
href="http://www.opensource.org/licenses/zlib-license.html">zlib/libpng
|
||||
license</a>. See license.txt in the distribution for text of license. The
|
||||
intent of the license is to:
|
||||
|
||||
<ul>
|
||||
|
||||
<li> Keep the license as simple as possible
|
||||
<li> Encourage the use of CuTest in both free and commercial applications and libraries
|
||||
<li> Keep the source code together
|
||||
<li> Give credit to the CuTest contributors for their work
|
||||
|
||||
</ul>
|
||||
|
||||
If you find CuTest useful we would like to hear about it.
|
||||
|
||||
|
||||
<h2>Getting Started</h2>
|
||||
|
||||
<p> 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.
|
||||
|
||||
<p> To add unit testing to your C code the only files you need
|
||||
are CuTest.c and CuTest.h.
|
||||
|
||||
<p> 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.
|
||||
|
||||
<p> You should not have to look inside CuTest.c. Looking in
|
||||
CuTestTest.c (for example usage) should be sufficient.
|
||||
|
||||
<p> After downloading the sources, run your compiler to create an
|
||||
executable called AllTests.exe. For example, if you are using
|
||||
Windows you would type:
|
||||
|
||||
<PRE CLASS="CONSOLE">
|
||||
cl AllTests.c CuTest.c CuTestTest.c
|
||||
AllTests.exe
|
||||
</PRE>
|
||||
|
||||
<p> This will run all the unit tests associated with CuTest and
|
||||
print the output on the console.
|
||||
|
||||
<p> For more details on how to use the library look at the README file included
|
||||
with the distribution.
|
||||
|
||||
<h2>Contribute</h2>
|
||||
|
||||
<p> We hope you CuTest saves you time and helps you produce high quality
|
||||
software.
|
||||
|
||||
<p> If you find CuTest useful, let us know. Tell us what platform you are using
|
||||
it on (Windows, Linux, etc), and what kinds of applications you are using it
|
||||
with.
