ExQuality.Printer (ExQuality v0.5.0)
View SourceSerializes output from parallel stages to prevent interleaving.
Each stage calls print_result/1 when complete, which acquires
a lock and prints the entire summary atomically. This ensures
that if multiple stages complete simultaneously, their output
won't be interleaved.
Usage
{:ok, _pid} = ExQuality.Printer.start_link()
# From multiple parallel tasks:
ExQuality.Printer.print_result(result)
ExQuality.Printer.stop()Summary
