我正在为我的需求构建一个完全开源的testrunner，但我遇到了一些问题。测试运行器为各种路径中的一组脚本解析yaml文件并执行脚本并使用我将创建的lib来返回结果。现在我有一个简单的ping脚本，我正在努力运行和测试，因为我进步但我收到了很多错误。错误如下，所有源代码也显示在错误下方。
这里的github回购就在这里。随意拉进来测试我看到的问题。 https://github.com/castaway2000/testrunner
问题：
我正在尝试使用我构建的testrunner来解析yaml文件，以获取我正在为我正在使用的项目编写的脚本的路径。
例如，如果想在目标上使用一组特定测试，我可以为每组测试类型创建一个yaml文件。
我遇到了一个问题然而，文件的相对路径和确切路径无法使用django库，导致它无法找到库的路径，除非它从顶层运行django应用程序（即./ping_google.py vs ./testcases/ping_google.py）
但最重要的是，当独立库引用models.py并且admin.py无法从同一目录导入模型时，django应用程序说没有运行。我需要帮助修复和理解这个问题。
这是rundown（stacktrace）：
Enterprize:testrunner xwing$ python3 ping_google.py
Traceback (most recent call last):

我在django设置文件中放入导入django和django.setup（）之后，上面的错误就消失了但是我收到以下错误：

修复此问题将有助于测试testrunner的其余构建场景，但我仍然需要有关python需要使用的相对路径和环境的建议，以了解在哪里查找这些库。如果可能的话，我可以将lib放在根python目录中，这样lib就与问题无关。
问题文件：
from testrunnerlib.test import HostInterface
from testrunnerlib.outcomes import Outcomes
from ping3 import ping
def pinger(host):
result = Outcomes()
try:
ping_google = ping(host)
print(ping_google)
if ping_google:
return result.passed()
msg = 'ping had an issue, the following is all we know %s' % ping_google
return result.failed(msg)
except Exception as e:
return result.aborted(exception=e)
if __name__ == '__main__':
pinger(HostInterface().target)
只有django导入的lib：
import yaml
import subprocess
from testrunner.models import Host, TestSuite
class HostInterface(object):
def __init__(self):
self._target = 'not set'
@property
def target(self):
return self._target
@target.setter
def target(self, value):
print("setter of target called", value)
self._target = value
@target.deleter
def target(self):
print("deleter of target called")
del self._target
def host(self):
out = Host.objects.get(id=self.target).name
return out
class YamlInterface:
def __init__(self, yamlfile):
self.file = yamlfile
def handle_yaml(self):
data = TestSuite.objects.get(id=self.file)
yamldata = yaml.safe_load(data.text)
for i in yamldata['testsuite']:
status = subprocess.call('python3 %s' % i, shell=True)
print(status)
def run_tests(host, yaml):
h_interface = HostInterface()
h_interface.target = host
h_interface.host()
yaml = YamlInterface(yaml)
yaml.handle_yaml()
模特：
from __future__ import unicode_literals
from django.db import models
class Host(models.Model):
ip_address = models.CharField(max_length=16)
port = models.IntegerField()
name = models.CharField(max_length=256)
class TestSuite(models.Model):
name = models.CharField(max_length=256)
text = models.TextField()
is_active = models.BooleanField(default=True)
created = models.DateTimeField(auto_now_add=True, auto_now=False)
updated = models.DateTimeField(auto_now_add=False, auto_now=True)
def __str__(self):
return "%s" % self.name
admin.py
from django.contrib import admin
from django import forms
from testrunner.models import Host, TestSuite
class HostAdmin(admin.ModelAdmin):
list_display = ['name']
fields = ('name', 'ip_address', 'port')
def __str__(self):
return '%s' % self.name
pass
admin.site.register(Host, HostAdmin)
class TestSuiteAdmin(admin.ModelAdmin):
def formfield_for_dbfield(self, db_field, **kwargs):
formfield = super(TestSuiteAdmin, self).formfield_for_dbfield(db_field, **kwargs)
if db_field.name == 'text':
formfield.widget = forms.Textarea(attrs=formfield.widget.attrs)
return formfield
admin.site.register(TestSuite, TestSuiteAdmin)

您需要制作Django管理命令。这将允许您创建允许您使用Django所有功能的脚本。
您可以将此命令作为python3 manage.py ping_google
运行要创建管理命令，
在你的apps文件夹中，创建一个名为management的模块（创建一个名为management的文件夹并在其中放置 init .py文件）
在管理文件夹中，创建一个命令模块（文件夹和 init .py文件）
在命令文件夹中创建ping_google.py文件。
命令是这样写的，
from django.core.management.base import BaseCommand, CommandError
class Command(BaseCommand):
help = 'Desc of your command'
def handle(self, *args, **options):
# Your logic goes here
您可以阅读有关自定义django命令here
