Lightweight unit testing framework mainly for C++ and also for C projects. Suitable for embedded devices.
## Key Features
* Written in C++11
* An XUnit test framework
* The 3-clause BSD license
* No evil defined test macros, programmer API style
* Detailed assert messages including type info, address and total size in bytes
* Automatic test registration
* Single registered test can have multi test suites and test cases
* A rich set of assertions
* Fatal and non-fatal assertions
* Support for multi reporters with multi writers
* Working with/without exceptions and RTTI
* Optionally running test case in isolate environment using thread
* Minimal virtual methods usage
* Small footprint, friendly for embedded target like Cortex-Mx microcontrollers
* Warnings free even on the most aggressive levels
* Support for Clang 3.5 and later
* Support for GCC 4.8 and later
## How to use it
* [Build under Linux](docs/build-linux.md)
* [Build for ARM target](docs/build-arm.md)
## Examples
Test source example:
```c++
#include
using namespace utest;
static unsigned int Factorial(unsigned int number) {
return number > 1 ? Factorial(number - 1) * number : 1;
}
static TestRunner g([] (TestSuite& test_suite) {
test_suite.name("Factorial").run([] (TestCase& test_case) {
test_case.name("computed").run([] (TestParams& p) {
TestAssert{p}.equal(Factorial(0), 1u);
TestAssert{p}.equal(Factorial(1), 1u);
TestAssert{p}.equal(Factorial(2), 2u);
TestAssert{p}.equal(Factorial(3), 6u);
TestAssert{p}.equal(Factorial(10), 3628800u);
});
});
});
```
Test output example:
```
[==========] Running 1 registered test runner(s).
[----------] Running test(s) from Factorial
[ RUN ] computed
[ OK ] computed
[----------] 1 test(s) from Factorial
[ PASSED ] 1 test(s).
[==========] 1 test(s) from 1 test suite(s) ran.
[ PASSED ] 1 test(s).
```
Test assert message examples:
```
unit_test.cpp:7: Failure
Expected: (boolean)[address=0x00007fa3b3411e08,size=1] is true
Actual: false
unit_test.cpp:13: Failure
Expected: (string)[address=0x00007fff4d0c00b0,size=4] == (string)[address=0x00000000004097ee,size=5]
Actual: "Text" == "TextB"
unit_test.cpp:17: Failure
Expected: (signed int)[address=0x00007fa3b3411dc8,size=4] == (signed int)[address=0x00007fa3b3411d98,size=4]
Actual: 1 == 2
```
Main example with multi writers:
```c++
#include
#include
#include
#include
#include
using namespace utest;
int main(int argc, char* argv[]) {
test_writer::UDP udp{"127.0.0.1", 51234};
test_writer::File out{stdout};
TestWriterRefence writers[]{
out,
udp
};
test_reporter::GoogleTest google_test{writers};
TestReporterReference reporters[]{
google_test
};
return TestStatus::PASS == Test{argc, argv}.run().status()
? EXIT_SUCCESS : EXIT_FAILURE;
}
```
Test example with evil macros extension:
```
#include
#include
UTEST_RUNNER()
UTEST_SUITE("integer compare")
int x = 0;
UTEST_CASE_CONTEXT(x);
UTEST_CASE_SETUP()
UTEST_CONTEXT(int) = 5;
UTEST_CASE_SETUP_END
UTEST_CASE("equal")
UTEST_EXPECT_EQ(UTEST_CONTEXT(int), 5);
UTEST_CASE_END
UTEST_CASE_SETUP()
UTEST_CONTEXT(int) = 4;
UTEST_CASE_SETUP_END
UTEST_CASE("not equal")
UTEST_EXPECT_NE(UTEST_CONTEXT(int), 5);
UTEST_CASE_END
UTEST_SUITE_END
UTEST_RUNNER_END
```
