robotframework 是一个简单易用的关键字驱动自动化测试框架，我这里用dbank的python的sdk作为目标测试程序简单使用robotframework
Why Robot Framework?
- Enables easy-to-use tabular syntax for creating test cases in a uniform way.
- Provides ability to create reusable higher-level keywords from the existing keywords.
- Provides easy-to-read result reports and logs in HTML format.
- Is platform and application independent.
- Provides a simple library API for creating customized test libraries which can be implemented natively with either Python or Java.
- Provides a command line interface and XML based output files for integration into existing build infrastructure (continuous integration systems).
- Provides support for Selenium for web testing, Java GUI testing, running processes, Telnet, SSH, and so on.
- Supports creating data-driven test cases.
- Has built-in support for variables, practical particularly for testing in different environments.
- Provides tagging to categorize and select test cases to be executed.
- Enables easy integration with source control: test suites are just files and directories that can be versioned with the production code.
- Provides test-case and test-suite -level setup and teardown.
- The modular architecture supports creating tests even for applications with several diverse interfaces.
首先安装并检测是否成功
pip install robotframework ciaos@linux-53dr:~/Downloads/python-sdk-0.1> pybot --version Robot Framework 2.7.6 (Python 2.7.3 on linux2)
修改demo.py为下面的代码（作为目标测试接口，命令行程序）
nspApi.py
#!/usr/bin/env python
from nsp import NSPClient
import sys
import os
def helloworld(uname):
nsp = NSPClient(****, '***********************');
svc = nsp.service("nsp.demo")
ret = svc.helloworld(uname)
print ret
def lsdir(path):
nsp = NSPClient('iuTeAN9uaQ6xYuCt8f7uaL4Hwua5CgiU2J0kYJq01KtsA4DY', 'c94f61061b46668c25d377cead92f898');
svc = nsp.service("nsp.vfs");
ret = svc.lsdir(path)
print ret
def help():
print 'Usage: %s { nsp.demo.helloworld | nsp.vfs.lsdir | help }' \
% os.path.basename(sys.argv[0])
if __name__ == '__main__':
actions = {'nsp.demo.helloworld': helloworld, 'nsp.vfs.lsdir': lsdir,
'help': help}
try:
action = sys.argv[1]
except IndexError:
action = 'help'
args = sys.argv[2:]
try:
actions[action](*args)
except (KeyError, TypeError):
help()
按照robotframework规范编写测试库如下
testLib/NspLibrary.py
#!/usr/bin/env python
import os
import sys
class NspLibrary:
def __init__(self):
self._nsp_path = os.path.join(os.path.dirname(__file__),
'..', '.', 'nspApi.py')
self._status = ''
def helloworld(self, name):
self._run_command('nsp.demo.helloworld', name)
def lsdir(self, path):
self._run_command('nsp.vfs.lsdir',path)
def status_should_be(self, expected_status):
if expected_status != self._status:
raise AssertionError("Expected status to be '%s' but was '%s'"
% (expected_status, self._status))
def _run_command(self, command, *args):
command = '"%s" %s %s' % (self._nsp_path, command, ' '.join(args))
process = os.popen(command)
self._status = process.read().strip()
process.close()
编写测试用例nspTest.tsv(必须以单个分割符\t区分关键字，不然会报错，不能用多个\t或者空格)
*** Settings ***
Library OperatingSystem
Library testLib/NspLibrary.py
*** Variables ***
${NAME} "PJ!"
${RES1} "{'message': 'Hello:PJ!'}"
${LSDIR_RES} "{'childList': {0: {'type': 'Directory', 'name': 'Netdisk'}, 1: {'type': 'Directory', 'name': 'Syncbox'}, 2: {'type': 'Directory', 'name': 'Recycle'}}}"
*** Test Cases ***
Demo Test [Tags] nsp.demo
[Documentation] Example test
Helloworld ${NAME}
Status should be ${RES1}
Another Test
Should Be Equal ${NAME} PJ!
VFS Test [Tags] nsp.vfs
Lsdir "/"
Status should be ${LSDIR_RES}
Lsdir "/Netdisk"
Status should be "Wrong results"
运行pybot nspTest.tsv，结果如下
ciaos@linux-53dr:~/Downloads/python-sdk-0.1> pybot nspTest.tsv
==============================================================================
nspTest
==============================================================================
Demo Test :: Example test | PASS |
------------------------------------------------------------------------------
Another Test | PASS |
------------------------------------------------------------------------------
VFS Test | FAIL |
Expected status to be 'Wrong results' but was '{'childList': {0: {'type': 'Directory', 'name': 'zhujhdir'}, 1: {'type': 'Directory', 'name': '\xe7\x85\xa7\xe7\x89\x87'}, 2: {'type': 'Directory', 'name': '\xe6\x96\x87\xe6\xa1\xa3'}, 3: {'type': 'Directory', 'name': '\xe6\x88\x91\xe6\x94\xb6\xe5\x88\xb0\xe7\x9a\x84\xe6\x96\x87\xe4\xbb\xb6'}, 4: {'type': 'Directory', 'name': '\xe6\x88\x91\xe7\x9a\x84\xe6\x96\x87\xe4\xbb\xb6'}, 5: {'type': 'Directory', 'name': '\xe8\xbd\xaf\xe4\xbb\xb6'}, 6: {'type': 'File', 'name': '\xe6\x88\x91\xe7\x9a\x84\xe6\xb5\x8b\xe8\xaf\x95.php'}, 7: {'type': 'File', 'name': 'data.txt'}, 8: {'type': 'File', 'name': 'test.thrift'}, 9: {'type': 'File', 'name': 'acds4.txt'}, 10: {'type': 'File', 'name': 'nsp_sdk.log'}, 11: {'type': 'File', 'name': 'data.rar'}, 12: {'type': 'File', 'name': 'test.rar'}}}'
------------------------------------------------------------------------------
nspTest | FAIL |
3 critical tests, 2 passed, 1 failed

此外robotframe包含丰富的测试工具，如内置测试库以及用于测试web接口的requests库，直接使用request测试库可以免去我们编写web请求的工作。
安装顺序
pip install -U requests==0.9.0
pip install -U robotframework-requests
使用示例：
WEB TEST [Tags] web.test
Create Session vmall http://api.vmall.com
${resp}= GET vmall /rest.php
Should Be Equal As Strings ${resp.status_code} 200
log ${resp.content}
Should Contain ${resp.content} "param"
${json}= To JSON ${resp.content}
Dictionary Should Contain Value ${json} "param error"
