Thanks for the reply.
Interestingly, there is no hypothesis code in the moviepy tests so I'm not sure
why we get that plugins output section mentioning hypothesis.
I wonder if there's a way to start pdb or pudb in the failed build environment
so that I can step through the test? hmmm
Will try that next... for fun
Here's one test that fails:
# -*- coding: utf-8 -*-
"""Image sequencing clip tests meant to be run with pytest."""
import os
import sys
import pytest
from moviepy.video.io.ImageSequenceClip import ImageSequenceClip
from .test_helper import TMP_DIR
def test_1():
images=[]
durations=[]
for i in range(5):
durations.append(i)
images.append("media/python_logo.png")
durations.append(i)
images.append("media/python_logo_upside_down.png")
with ImageSequenceClip(images, durations=durations) as clip:
assert clip.duration == sum(durations)
clip.write_videofile(os.path.join(TMP_DIR, "ImageSequenceClip1.mp4"),
fps=30)
def test_2():
images=[]
durations=[]
durations.append(1)
images.append("media/python_logo.png")
durations.append(2)
images.append("media/matplotlib_demo1.png")
#images are not the same size..
with pytest.raises(Exception):
ImageSequenceClip(images, durations=durations).close()
if __name__ == '__main__':
pytest.main()
and here's the test failure output:
