[英]Testing a python script with pytest - permission issues
I have unit tested my modules using pytest without issue. 我已经使用pytest对模块进行了单元测试,没有任何问题。 I would also like to test my script (which imports some of the modules), but I am getting a permission error.
我也想测试我的脚本(其中导入了一些模块),但是出现权限错误。 I am new to writing larger python projects that actually need to be tested and maintained, so my directory structure may be non-optimal, so please let me know if that is the case.
我是刚开始编写实际上需要测试和维护的大型python项目的新手,因此我的目录结构可能不是最佳的,所以请告诉我是否是这种情况。 My directory structure looks like -
我的目录结构看起来像-
parent
modules
__init__.py
module1.py
...
test
...
test_script.py
script.py
My test code: 我的测试代码:
import os
import subprocess
import train
def test_train_dataset1():
#run the script
p = subprocess.Popen(['./train.py', 'test_models', 'test1', 'data/temp.json', '--isfile'])
#more code to check output
My error: 我的错误:
PermissionError: [Errno 13] Permission denied: './train.py'
Permission denied: './train.py'
is most certainly mean the file is not executable. Permission denied: './train.py'
最肯定意味着该文件不可执行。 To fix: 修理:
chmod a+x ./train.py
Also verify it has a proper shebang line ( #!/usr/bin/python
or such). 还要验证它是否具有正确的shebang行(
#!/usr/bin/python
等)。
PS. PS。 When you do
import train
do you import from the same train.py
? import train
,您是否从同一train.py
进口? If not — you shouldn't give the script the same name as a module/package you're gonna import. 如果不是,则不应为脚本提供与要导入的模块/软件包相同的名称。
