我一直都是读者,但这是我第一次发帖。
好的,我正在尝试在Flask中对一个演示应用程序进行单元测试,但我不知道我做错了什么。
这些是我在名为 manager.py 的文件中的“路线”:
@app.route('/')
@app.route('/index')
def hello():
return render_template('base.html')
@app.route('/hello/<username>')
def hello_username(username):
return "Hello %s" % username
第一个路径是加载base.html模板呈现“hi”消息,该消息在单元测试中工作,但第二个路由获得断言错误。
这是我的测试文件 manage_test.py :
class ManagerTestCase(unittest.TestCase):
def setUp(self):
self.app = app.test_client()
def t_username(self, username):
return self.app.post('/hello/<username>', follow_redirects=True)
def test_username(self):
rv = self.t_username('alberto')
assert "Hello alberto" in rv.data
def test_empty_db(self):
rv = self.app.get('/')
assert 'hi' in rv.data
这是单元测试运行的输出:
.F
======================================================================

我想知道你们是否可以帮助我!我做错了什么或错过了什么?
修改
我做了这个并且它正在工作
class ManagerTestCase(unittest.TestCase):
def setUp(self):
self.app = app.test_client()
def t_username(self, username):
return self.app.get('/hello/%s' % (username), follow_redirects=True')
# either that or the Advanced string formatting from the answer are working.
def test_username(self):
rv = self.t_username('alberto')
assert "Hello alberto" in rv.data
def test_empty_db(self):
rv = self.app.get('/')
assert 'hi' in rv.data
def setUp(self):
self.app = app.test_client()
def t_username(self, username):
return self.app.get('/hello/%s' % (username), follow_redirects=True')
# either that or the Advanced string formatting from the answer are working.
def test_username(self):
rv = self.t_username('alberto')
assert "Hello alberto" in rv.data
def test_empty_db(self):
rv = self.app.get('/')
assert 'hi' in rv.data
答案 0 :(得分:2)
您应该将hello_username
更改为以下内容:
@app.route('/hello/', methods=['POST'])
def hello_username():
return "Hello %s" % request.form.get('username', 'nobody')
确保from flask import request
也是。
一个例子,显示它有效:
> curl -X POST -i 'http://localhost:2000/hello/' -d "username=alberto"
HTTP/1.0 200 OK
Content-Type: text/html; charset=utf-8

Hello alberto
您的测试应如下所示:
def test_username(self, username):
return self.app.post('/hello', data={"username":username})
修改强>
根据你的评论:
@app.route('/hello/<username>', methods=['POST'])
def hello_username(username):
print request.args
return "Hello %s" % username
但是,我不知道你为什么要使用POST,因为这本质上是一个没有任何POST主体的POST。
> curl -X POST -i 'http://localhost:2000/hello/alberto'
HTTP/1.0 200 OK
Content-Type: text/html; charset=utf-8

Hello alberto
在这种情况下,我会一起删除对POST数据的要求:
@app.route('/hello/<username>', methods=['POST'])
def hello_username(username):
print request.args
return "Hello %s" % username
> curl -i 'http://localhost:2000/hello/alberto'
HTTP/1.0 200 OK
Content-Type: text/html; charset=utf-8

使用GET的测试将是
def test_username(self, username):
return self.app.get('/hello/%s' % (username), follow_redirects=True)
或者,假设您有2.6 +,
def test_username(self, username):
return self.app.get('/hello/{username}'.format(username=username), follow_redirects=True)
