该程序允许自动运行几个Arduino单元测试。测试过程在PC上启动，但测试在实际的Arduino硬件上运行。一组单元测试通常用于测试一个Arduino库。 (这

单元测试是用“Arduino单元测试库”编写的:http://code.google.com/p/arduinounit

对每组单元测试执行以下步骤:

Read the config file to find out which tests to run The script compiles and uploads an Arduino sketch that contains the unit testing code. The unit tests are run on the Arduino board. The results of the test are printed over the serial port and analyzed by the Python script. The script starts the next test, repeating the above steps for all test that are requested in the configuration file. The script prints a summary showing an overview of all the failed/passed tests in the complete testsuite.

simavr是一个使用AVR -gcc的AVR模拟器。

它已经支持一些ATTiny和ATMega微控制器，而且根据作者的说法，很容易添加更多的微控制器。

示例中包含simduino，这是一个Arduino模拟器。它支持运行Arduino引导加载程序，并可以通过Socat(修改后的Netcat)使用avrdude进行编程。

如果您有兴趣运行INO草图并检查串行输出，我在我的Arduino NMEA校验和项目中有一个工作实现。

下面的脚本获取该文件，并使用Arduino CLI将其编译为HEX文件，然后加载到SimAVR中，SimAVR对其进行计算并打印串行输出。由于所有Arduino程序都永远运行，没有真正杀死自己的选项(exit(0)不起作用)，我让草图运行几秒钟，然后将捕获的输出与预期的输出进行区分。

下载并提取Arduino CLI(在本例中，版本为0.5.0 -撰写本文时的最新版本):

curl -L https://github.com/arduino/arduino-cli/releases/download/0.5.0/arduino-cli_0.5.0_Linux_64bit.tar.gz -o arduino-cli.tar.gz
tar -xvzf arduino-cli.tar.gz

现在你可以更新索引并安装相应的核心:

./arduino-cli core update-index
./arduino-cli core install arduino:avr

假设你的草图名为nmea-checksum。ino，获取ELF和HEX，运行:

./arduino-cli compile -b arduino:avr:uno nmea-checksum.ino

接下来，SimAVR运行HEX(或ELF) -我从源代码构建，因为最新版本不适合我:

sudo apt-get update
sudo apt-get install -y build-essential libelf-dev avr-libc gcc-avr freeglut3-dev libncurses5-dev pkg-config
git clone https://github.com/buserror/simavr.git
cd simavr
make

成功的编译将为您提供simavr/run_avr，您可以使用它来运行草图。就像我说的，暂停它，否则它永远不会终止:

cd simavr
timeout 10 ./run_avr -m atmega168 -f 16000000 ../../nmea-checksum.ino.arduino.avr.uno.elf &> nmea-checksum.ino.clog || true

生成的文件将有ANSI颜色代码控制字符包装串行输出，以摆脱这些:

cat nmea-checksum.ino.clog | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g" > nmea-checksum.ino.log
cat nmea-checksum.ino.log

现在你所需要做的就是将这个文件与一个已知的好文件进行比较:

diff nmea-checksum.ino.log ../../nmea-checksum.ino.test

如果没有差异，diff将以代码0退出，否则脚本将失败。

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。

看起来乳香就能完美地完成这项工作。

Emulino是Greg Hewgill为Arduino平台开发的模拟器。(源)

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).
