我希望能够单元测试我的Arduino代码。理想情况下,我可以运行任何测试,而无需将代码上传到Arduino。哪些工具或库可以帮助我做到这一点?

目前正在开发的Arduino模拟器可能很有用,但似乎还没有准备好使用。

Atmel的AVR Studio包含一个芯片模拟器,可能很有用,但我不知道如何将它与Arduino IDE结合使用。

你可以使用仿真——你可以在图表上拖放微控制器,然后在Eclipse中运行你的代码。网站上的文档会告诉你如何设置。

有一个叫ncore的项目,它为Arduino提供了原生内核。并允许您为Arduino代码编写测试。

来自项目描述

本机核心允许您编译和运行Arduino草图 PC,一般无需修改。的原生版本 标准的Arduino功能,以及一个命令行解释器 草图的输入通常来自硬件 本身。

同样在“我需要使用它什么”部分

如果要构建测试,则需要从 http://cxxtest.tigris.org。NCORE已经用cxxtest 3.10.1进行了测试。

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).

我在编写Arduino代码时使用Searduino。Searduino是Arduino模拟器和开发环境(Makefiles, C代码…),可以使用您最喜欢的编辑器在C/ c++中轻松破解。您可以导入Arduino草图并在模拟器中运行它们。

Searduino 0.8截图:http://searduino.files.wordpress.com/2014/01/jearduino-0-8.png

Searduino 0.9将发布,并在最后的测试完成后立即录制视频....一两天后。

在模拟器上测试并不是真正的测试,但它确实帮助我找到了许多愚蠢的/逻辑错误(忘记执行pinMode(xx, OUTPUT)等)。

顺便说一句:我是Searduino开发人员之一。

保持特定于硬件的代码与其他代码分离或抽象,这样您就可以在任何拥有良好工具和最熟悉的平台上测试和调试更大的“休息”。

Basically, try to build as much of the final code from as many known-to-work building blocks as possible. The remaining hardware-specific work will then be much easier and faster. You may finish it by using existing emulators and/or emulating devices on your own. And then, of course, you'll need to test the real thing somehow. Depending on circumstances, that may or may not be very well automatable (i.e. who or what will press buttons and provide other inputs? who or what will observe and interpret various indicators and outputs?).
