如何在GAE上使用Google云端存储的模型上运行本地单元测试(python) [英] How can I run local unit tests on models that use Google Cloud Storage on GAE (python)
问题描述
我试图为调用存储在谷歌云存储上的文件的模型编写单元测试,但是我没有找到关于如何模拟单元测试的GCS服务的示例。
似乎应该有一个存根服务我可以使用,并在
import peewee
from google.appengine.api import app_identity
import cloudstorage
类示例(模型):
uuid = peewee.CharField(default = uuid4)
some_property = peewee.CharField()
@属性
def raw_file_one(self):
bucket = app_identity.get_default_gcs_bucket_name()
filename ='/{0}/repo_one/{1}'.format(bucket,self.uuid)
with cloudstorage.open(filename,'r')as f:
return f.read()
def store_raw_file(self,raw_file_one):
bucket = app_identity.get_default_gcs_bucket_name()
filename =' /{0}/stat_doms/{1}'.format(bucket,self.uuid)
with cloudstorage.open(filename,'w')as f:
f.write(raw_file_one)
我将构建测试用例:
import unittest
from google.appengine.ext import testbed
class TestCase(unittest.TestCase):
def run( (),$ args,** kwargs)
self.stub_google_services()
result = super(TestCase,self).run(* args,** kwargs)
self.unstub_google_services()
返回结果
def stub_google_services(self) :
self.testbed = testbed.Testbed()
self.testbed.activate()
self.testbed.init_all_stubs()
$ b $ def unstub_google_services(self):
self.testbed.deactivate()
进入如下模块测试:
$从application.tests.testcase导入TestCase从application.models导入示例
class ExampleTest(TestCase) :
def test_store_raw_file(self):
...
[assert something]
我假设我会做一些像 blobstore = self.testbed.get_stub('blobstore')
来创建一个服务,我可以对其执行测试(例如 blobstore.CreateBlob(blob_key,image)
) - 但我在测试平台的参考文档中看不到GCS的服务。
关于如何使用GCS实现单元测试的想法?
我想你正在寻找:
from google.appengine.ext.cloudstorage import cloudstorage_stub $ b $ from google.appengine.api.blobstore import blobstore_stub
和:
blob_stub = blobstore_stub.BlobstoreServiceStub(blob_storage)
storage_stub = cloudstorage_stub.CloudStorageStub(blob_storage)
testbed._register_stub('blobstore',self.blob_stub)
testbed._register_stub( cloudstorage,self.storage_stub)
I'm trying to write unit tests for a model that calls on files stored on google cloud storage, but I haven't found any examples on how to simulate the GCS service for unit testing.
It seems that there should be a stub service I can use, and I see some references to gcs within the testbed docs described there, but haven't nailed down an example using it I can work off of.
Here's a condensed/example version of the model I have:
import peewee
from google.appengine.api import app_identity
import cloudstorage
class Example(Model):
uuid = peewee.CharField(default=uuid4)
some_property = peewee.CharField()
@property
def raw_file_one(self):
bucket = app_identity.get_default_gcs_bucket_name()
filename = '/{0}/repo_one/{1}'.format(bucket, self.uuid)
with cloudstorage.open(filename, 'r') as f:
return f.read()
def store_raw_file(self, raw_file_one):
bucket = app_identity.get_default_gcs_bucket_name()
filename = '/{0}/stat_doms/{1}'.format(bucket, self.uuid)
with cloudstorage.open(filename, 'w') as f:
f.write(raw_file_one)
I'll build test cases with:
import unittest
from google.appengine.ext import testbed
class TestCase(unittest.TestCase):
def run(self, *args, **kwargs):
self.stub_google_services()
result = super(TestCase, self).run(*args, **kwargs)
self.unstub_google_services()
return result
def stub_google_services(self):
self.testbed = testbed.Testbed()
self.testbed.activate()
self.testbed.init_all_stubs()
def unstub_google_services(self):
self.testbed.deactivate()
Into module tests like:
from application.tests.testcase import TestCase
from application.models import Example
class ExampleTest(TestCase):
def test_store_raw_file(self):
...
[assert something]
I presume I'd do something like blobstore = self.testbed.get_stub('blobstore')
to create a service I can perform tests on (e.g. blobstore.CreateBlob(blob_key, image)
) -- but I don't see a service for GCS in the testbed ref docs.
Thoughts on how to implement unit tests with GCS?
I think you're looking for:
from google.appengine.ext.cloudstorage import cloudstorage_stub
from google.appengine.api.blobstore import blobstore_stub
and:
blob_stub = blobstore_stub.BlobstoreServiceStub(blob_storage)
storage_stub = cloudstorage_stub.CloudStorageStub(blob_storage)
testbed._register_stub('blobstore', self.blob_stub)
testbed._register_stub("cloudstorage", self.storage_stub)
