When the test fails, it usually ends up failing on the assertion that
wc
did not find as many bytes as it expected. That may not behelpful if it is caused by a failure earlier in the command
pipeline ( cat | grep | wc ). Move the byte check to
process.on('exit')
so that other error handlers that report theexistence of errors run first.
