testlike

utility for testing programs in C.

installation

git clone git@github.com:Omarmeks89/testlike.git

You can cp ctest.h into your project directory and include it like "../testlike.h" or make a softlink and use in by name:

sudo ln -s $(pwd)/testlike.h /usr/include/testlike.h

build tests

You can compile and run base test:

make

or you may compile tests in quiet mode - messages for sucessfull tests will be ignored:

make QUIET=-DQUIET

You can redirect success and error outputs to different output streams. ESTRM (error stream) parameter responsible to set output stream for errors (stderr by default). MSTRM (message stream) parameter responsible to set output stream for messages (stdout by default).

make ESTRM=2 MSTRM=2

compiler version and OS

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

ABOUT

Minimal utility for simple test cases. If you`re working on your simple pet-project this tool may be useful. Can be integrated directly into code (instead of assert) or used in separate test functions. String comparison and support for table tests will be added in future versions.

It consists of only one header file and does not require third-party libraries. Note that the math library is used. Take this into account when compiling tests.

Usage

ASSERT will break execution if testcase failed:

ASSERT_EQ_INT32(result, expected_value, test_title, line_number);

You can use macro LINE() to set line number.

ASSERT_EQ_DBL(result, expected_value, epsilon, test_title, line_number);

testlike provide several epsilons or you may use from float.h:

#define DBL_e_9 1e-9
#define DBL_e_8 1e-8
#define DBL_e_7 1e-7
#define DBL_e_6 1e-6
#define DBL_e_5 1e-5
#define DBL_e_4 1e-4
#define DBL_e_3 1e-3
#define DBL_e_2 1e-2
#define DBL_e_1 1e-1

NE (not equal) may be useful in some cases like:

ASSERT_NE_PTR_NULL(pointer, test_title, line_number);

EXPECT will not break execution and you can see all results. ASSERT and EXPECT use the same arguments in same order.

Example

#include "testlike.h"

void test_assert_eq_dbl_success() {
    double exp = 10.0, res = 0.0;
    res = func_that_return_double();
    ASSERT_EQ_DBL(res, exp, DBL_e_2, "wished_test_name", LINE());
}


void test_expect_eq_int32() {
    int exp = 10, res = 0;
    res = func_that_return_int32();
    EXPECT_EQ_INT32(res, exp, "wished_test_name", LINE());
}

int main() {
    test_expect_eq_int32();
    test_assert_eq_dbl_success();
    return 0;
}

Below is output example (for double):

test_assert_eq_dbl_success                  [EXP.: 10.000000, GOT: 10.000000, EPS.: 0.010000]     PASSED.
test_assert_ne_dbl_passed                            [10.011000 != 10.000000. EPS.: 0.010000]     PASSED.
test_expect_eq_dbl_passed                   [EXP.: 10.010000, GOT: 10.010000, EPS.: 0.010000]     PASSED.
test_expect_ne_dbl_passed                            [10.000001 != 10.000000. EPS.: 0.000001]     PASSED.

(for int32):

test_assert_eq_int32                                                      [EXP.: 10, GOT: 10]     PASSED.
test_expect_eq_int32                                                      [EXP.: 10, GOT: 10]     PASSED.
test_expect_ne_int32_passed                                                         [10 != 8]     PASSED.
test_assert_ne_int32_passed                                                         [10 != 0]     PASSED.
test_expect_ne_int32_failed  (LINE 31)                                             [10 == 10]     FAILED.

(for pointers):

null_ptr_test_1                                                              [NULLPTR: (nil)]     PASSED.
null_ptr_test_2                                               [PTR NOT NULL. ADDR.: 0xffabef]     PASSED.
expect_null_ptr_test_3                                                       [NULLPTR: (nil)]     PASSED.
not_null_ptr_test_4                                           [PTR NOT NULL. ADDR.: 0xffabef]     PASSED.
