Unit tests
|
|
==========
|
|
|
|
The goal is to add tests for *ALL* functions in libcurl. If functions are too
|
|
big and complicated, we should split them into smaller and testable ones.
|
|
|
|
Build Unit Tests
|
|
================
|
|
|
|
'./configure --enable-debug' is required for the unit tests to build. To
|
|
enable unit tests, there will be a separate static libcurl built that will be
|
|
used exclusively for linking unit test programs. Just build everything as
|
|
normal, and then you can run the unit test cases as well.
|
|
|
|
Run Unit Tests
|
|
==============
|
|
|
|
Unit tests are run as part of the regular test suite. If you have built
|
|
everything to run unit tests, to can do 'make test' at the root level. Or you
|
|
can 'cd tests' and then invoke individual unit tests with ./runtests.pl NNNN
|
|
where NNNN is the specific test number.
|
|
|
|
Debug Unit Tests
|
|
================
|
|
|
|
If a specific test fails you will get told. The test case then has output left
|
|
in the log/ subdirectory, but most importantly you can re-run the test again
|
|
using gdb by doing ./runtests.pl -g NNNN. That is, add a -g to make it start
|
|
up gdb and run the same case using that.
|
|
|
|
Write Unit Tests
|
|
================
|
|
|
|
We put tests that focus on an area or a specific function into a single C
|
|
source file. The source file should be named 'unitNNNN.c' where NNNN is a
|
|
number that starts with 1300 and you can pick the next free number.
|
|
|
|
You also need a separate file called tests/data/testNNNN (using the same
|
|
number) that describes your test case. See the test1300 file for inspiration
|
|
and the tests/FILEFORMAT documentation.
|
|
|
|
For the actual C file, here's a very simple example:
|
|
|
|
----------------------- start -------------------------------
|
|
#include "curlcheck.h"
|
|
|
|
#include "a libcurl header.h" /* from the lib dir */
|
|
|
|
static void unit_setup( void )
|
|
{
|
|
/* whatever you want done first */
|
|
}
|
|
|
|
static void unit_stop( void )
|
|
{
|
|
/* done before shutting down and exiting */
|
|
}
|
|
|
|
UNITTEST_START
|
|
|
|
/* here you start doing things and checking that the results are good */
|
|
|
|
fail_unless( size == 0 , "initial size should be zero" );
|
|
fail_if( head == NULL , "head should not be initiated to NULL" );
|
|
|
|
/* you end the test code like this: */
|
|
|
|
UNITTEST_STOP
|
|
|
|
----------------------- end -------------------------------
