J'essaye de capturer la sortie des instructions stdout/print dans pytest (Python version 3.6).Python pytest: la capture stdout échoue toujours
Cela échoue toujours:
message = 'The meaning of life is not actually 42\n'
def print_greeting():
"""print 42 to stdout"""
# write to stdout
sys.stdout.write(message) # this fails
# print to stdout
print('Message again: ', message) # this fails too
def test_printgreeting(capsys):
"""assert '42' was printed to stdout"""
# capture stdout/stderr
out, err = capsys.readouterr()
print_greeting()
# 42 should be in stdout from sys.stdout.write
assert '42' in out
