我一直在像这样运行我的 Python 2.7 单元测试
python -m unittest discover -s tests -b
Run Code Online (Sandbox Code Playgroud)
我想在 PyCharm 中运行它们,但是,我不知道如何发送 -b 缓冲区选项发送到 PyCharm 测试运行器。我在运行/调试配置中尝试了很多设置,但都没有成功。
如何在 PyCharm 中配置运行单元测试,以便每次运行“Unittests in test”时都使用 -b 参数运行?
我正在使用 Flask-Restless 0.17 作为 API。API 有几个小数字段。我可以通过安装 simplejson 成功返回小数,如下所述: https: //stackoverflow.com/a/15224186/1753891。
但是,当我的小数字段为 0 时,该值采用科学记数法,例如0E-8
。我想转而返回0.00000000
。
我正在尝试类似的事情,但无法让它发挥作用。0 仍然以科学记数法返回。
