Hi,
I download and install pyPDF2 library online. It says the test can run by:
python -m unittest Tests.tests
tests.py is under folder PyPDF2-master\Tests\
The above command line does run and give output message, but I don't
understand why it run after I read tests.py:
///////////////////////////////
import os, sys, unittest
# Configure path environment
TESTS_ROOT = os.path.abspath(os.path.dirname(__file__))
PROJECT_ROOT = os.path.dirname(TESTS_ROOT)
RESOURCE_ROOT = os.path.join(PROJECT_ROOT, 'Resources')
sys.path.append(PROJECT_ROOT)
# Test imports
import unittest
from PyPDF2 import PdfFileReader
class PdfReaderTestCases(unittest.TestCase):
def test_PdfReaderFileLoad(self):
''' Test loading and parsing of a file. Extract text of the
file and compare to expected
textual output. Expected outcome: file loads, text
matches expected.
'''
with open(os.path.join(RESOURCE_ROOT, 'crazyones.pdf'), 'rb')
as inputfile:
# Load PDF file from file
ipdf = PdfFileReader(inputfile)
ipdf_p1 = ipdf.getPage(0)
# Retrieve the text of the PDF
pdftext_file = open(os.path.join(RESOURCE_ROOT,
'crazyones.txt'), 'r')
pdftext = pdftext_file.read()
ipdf_p1_text = ipdf_p1.extractText()
# Compare the text of the PDF to a known source
self.assertEqual(ipdf_p1_text.encode('utf-8',
errors='ignore'), pdftext,
msg='PDF extracted text differs from expected
value.\n\nExpected:\n\n%r\n\nExtracted:\n\n%r\n\n'
% (pdftext,
ipdf_p1_text.encode('utf-8', errors='ignore')))
//////////////////////////////////////
It only gives a class PdfReaderTestCases() substantiation. I have read
usage on class, but I have not found the answer.
Can you help me on why the command line can run the test?
Thanks,
