怎样从0开始搭建一个测试框架_4——报告

怎样从0开始搭建一个测试框架_4

这一步我们需要用到并修改HTMLTestRunner.py，它本身是基于PY2的，简单而实用，之前博主对其进行了美化，并且改成了中文（下载链接）。

现在博主基于此进行了对PY3的修改，增加了对subTest的支持。

【更新】增加了一个用Echarts做的统计图，见github

StringIO -> io

去掉decode

增加addSubTest()

部分修改内容：

# import StringIO  # PY3改成了io库
import io
...
def startTest(self, test):
TestResult.startTest(self, test)
# just one buffer for both stdout and stderr
# self.outputBuffer = StringIO.StringIO()
self.outputBuffer = io.StringIO()
...
# 添加addSubTest方法，将有subTest的Case拆分成多个Case，均在报告中输出。这点处理与unittest的TextRunner并不相同，细心的同学可以试验下，看看它是怎么处理的。
def addSubTest(self, test, subtest, err):
if err is not None:
if getattr(self, 'failfast', False):
self.stop()
if issubclass(err[0], test.failureException):
self.failure_count += 1
errors = self.failures
errors.append((subtest, self._exc_info_to_string(err, subtest)))
output = self.complete_output()
self.result.append((1, test, output + '\nSubTestCase Failed:\n' + str(subtest),
self._exc_info_to_string(err, subtest)))
if self.verbosity > 1:
sys.stderr.write('F  ')
sys.stderr.write(str(subtest))
sys.stderr.write('\n')
else:
sys.stderr.write('F')
else:
self.error_count += 1
errors = self.errors
errors.append((subtest, self._exc_info_to_string(err, subtest)))
output = self.complete_output()
self.result.append(
(2, test, output + '\nSubTestCase Error:\n' + str(subtest), self._exc_info_to_string(err, subtest)))
if self.verbosity > 1:
sys.stderr.write('E  ')
sys.stderr.write(str(subtest))
sys.stderr.write('\n')
else:
sys.stderr.write('E')
self._mirrorOutput = True
else:
self.subtestlist.append(subtest)
self.subtestlist.append(test)
self.success_count += 1
output = self.complete_output()
self.result.append((0, test, output + '\nSubTestCase Pass:\n' + str(subtest), ''))
if self.verbosity > 1:
sys.stderr.write('ok ')
sys.stderr.write(str(subtest))
sys.stderr.write('\n')
else:
sys.stderr.write('.')
...
def run(self, test):
"Run the given test case or test suite."
result = _TestResult(self.verbosity)
test(result)
self.stopTime = datetime.datetime.now()
self.generateReport(test, result)
# print >>>sys.stderr '\nTime Elapsed: %s' % (self.stopTime-self.startTime)  # PY3的print需处理
print('\nTime Elapsed: %s' % (self.stopTime-self.startTime), file=sys.stderr)
return result
...
# PY3这里不用decode了，直接处理
# if isinstance(o,str):
#             # TODO: some problem with 'string_escape': it escape \n and mess up formating
#             # uo = unicode(o.encode('string_escape'))
#             # uo = o.decode('latin-1')
#             uo = o.decode('utf-8')
#         else:
#             uo = o
#         if isinstance(e,str):
#             # TODO: some problem with 'string_escape': it escape \n and mess up formating
#             # ue = unicode(e.encode('string_escape'))
#             # ue = e.decode('latin-1')
#             ue = e.decode('utf-8')
#         else:
#             ue = e

script = self.REPORT_TEST_OUTPUT_TMPL % dict(
id = tid,
# output = saxutils.escape(uo+ue),
output = saxutils.escape(o+e),
)

以上代码列出大部分主要修改。博主在GitHub上上传了该文件，目前仅是简单做了点修改，没有经过正式的测试，之后可能会进行更多改动，感兴趣的可以star下来，或者自己进一步修改。

传送门

你也自己编写自己的Report Runner，并不很复杂。

将其放在utils目录中，然后我们再次修改test_baidu：

import time
import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from utils.config import Config, DRIVER_PATH, DATA_PATH, REPORT_PATH
from utils.log import logger
from utils.file_reader import ExcelReader
from utils.HTMLTestRunner import HTMLTestRunner

class TestBaiDu(unittest.TestCase):
URL = Config().get('URL')
excel = DATA_PATH + '/baidu.xlsx'

locator_kw = (By.ID, 'kw')
locator_su = (By.ID, 'su')
locator_result = (By.XPATH, '//div[contains(@class, "result")]/h3/a')

def sub_setUp(self):
self.driver = webdriver.Chrome(executable_path=DRIVER_PATH + '\chromedriver.exe')
self.driver.get(self.URL)

def sub_tearDown(self):
self.driver.quit()

def test_search(self):
datas = ExcelReader(self.excel).data
for d in datas:
with self.subTest(data=d):
self.sub_setUp()
self.driver.find_element(*self.locator_kw).send_keys(d['search'])
self.driver.find_element(*self.locator_su).click()
time.sleep(2)
links = self.driver.find_elements(*self.locator_result)
for link in links:
logger.info(link.text)
self.sub_tearDown()

if __name__ == '__main__':
report = REPORT_PATH + '\\report.html'
with open(report, 'wb') as f:
runner = HTMLTestRunner(f, verbosity=2, title='从0搭建测试框架 灰蓝', description='修改html报告')
runner.run(TestBaiDu('test_search'))

执行后，可以在report目录下看到有

report.html

文件，我们已经生成测试报告了。
