如果你想在MCU之外(在桌面上)进行单元测试，请检查libcheck: https://libcheck.github.io/check/

我用它测试了几次我自己的嵌入式代码。这是一个非常健壮的框架。

在没有Arduino单元测试框架的情况下，我创建了ArduinoUnit。下面是一个简单的Arduino草图，展示了它的使用:

#include <ArduinoUnit.h>

// Create test suite
TestSuite suite;

void setup() {
    Serial.begin(9600);    
}

// Create a test called 'addition' in the test suite
test(addition) {
    assertEquals(3, 1 + 2);
}

void loop() {
    // Run test suite, printing results to the serial port
    suite.run();
}

We are using Arduino boards for data acquisition in a large scientific experiment. Subsequently, we have to support several Arduino boards with different implementations. I wrote Python utilities to dynamically load Arduino hex images during unit testing. The code found on the link below supports Windows and Mac OS X via a configuration file. To find out where your hex images are placed by the Arduino IDE, hit the shift key before you hit the build (play) button. Hit the shift key while hitting upload to find out where your avrdude (command line upload utility) is located on your system / version of Arduino. Alternatively, you can look at the included configuration files and use your install location (currently on Arduino 0020).

试试Autodesk电路模拟器。它允许用许多其他硬件组件测试Arduino代码和电路。

你可以在我的项目PySimAVR中使用Python进行单元测试。Arscons用于构建，simavr用于模拟。

例子:

from pysimavr.sim import ArduinoSim    
def test_atmega88():
    mcu = 'atmega88'
    snippet = 'Serial.print("hello");'

    output = ArduinoSim(snippet=snippet, mcu=mcu, timespan=0.01).get_serial()
    assert output == 'hello'

开始测试:

$ nosetests pysimavr/examples/test_example.py
pysimavr.examples.test_example.test_atmega88 ... ok
