Nota A quei tempi il progetto si chiamava solo “trash” (come il comando) 31 @andreafrancia #trash-cliSaturday, March 24, 12 31

Reviewer“ The name of this package is also a bit too generic, though not that much.Saturday, March 24, 12 32 @andreafrancia ” #trash-cli 32

Reviewer“ Could upstream change it to be less generic? https:/Saturday, March 24, 12 33 ” /bugzilla.redhat.com/show_bug.cgi?id=448122#c1 @andreafrancia #trash-cli 33

Developer“ Ok I’ll change to trash-cli.Saturday, March 24, 12 34 @andreafrancia ” #trash-cli 34

Reviewer“ [Ok...but...] The name of the command should also be trash- cli. https:/Saturday, March 24, 12 35 ” /bugzilla.redhat.com/show_bug.cgi?id=448122#c6 @andreafrancia #trash-cli 35

Developer“ The name of the main command is trash without "-cli".Saturday, March 24, 12 36 @andreafrancia ” #trash-cli 36

Developer“ The command is used is this way: $ trash this-file That means: "trash this-file in the trashcan", there is no reason to append the "-cli" suffix to the main command.Saturday, March 24, 12 37 @andreafrancia ” #trash-cli 37

Developer“ You are already using the Command Line Interface.Saturday, March 24, 12 38 @andreafrancia ” #trash-cli 38

Developer“ In my opinion each command name should reflect what the command does.Saturday, March 24, 12 39 @andreafrancia ” #trash-cli 39

Reviewer“ As far as possible.Saturday, March 24, 12 40 @andreafrancia ” #trash-cli 40

Risultati 81 @andreafrancia #trash-cliSaturday, March 24, 12 81

Bash Tests are slooow! 82 @andreafrancia #trash-cliSaturday, March 24, 12 82

Little information in failure messages 83 @andreafrancia #trash-cliSaturday, March 24, 12 83

Test Se Allora li usi 91 @andreafrancia #trash-cliSaturday, March 24, 12 91

Quindi Meglio se tutti omogenei (e.g. tutto python) 92 @andreafrancia #trash-cliSaturday, March 24, 12 92

Bash Tests? Ok, ma pochi. 93 @andreafrancia #trash-cliSaturday, March 24, 12 93

shUnit non serve a niente Si può fare tutto in bash 94 @andreafrancia #trash-cliSaturday, March 24, 12 94
