Feature: Shell Completion
We want to get the correct completion on the CLI.
Background:
Given SDKMAN! candidate list is up to date
And candidate ant is installed at version 1.9.9
And candidate ant is installed at version 1.10.1
And candidate crash is installed
Scenario: Command list correct
When the user enters " " into the prompt
Then completion should propose "b, broadcast, c, current, d, default, flush, h, help, i, install, list, ls, offline, rm, selfupdate, u, ug, uninstall, update, upgrade, use, v, version"
Scenario Outline: Commands complete
When the user enters "<cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| b | b, broadcast |
| c | c, current |
| d | d, default |
| f | flush |
| h | h, help |
| i | i, install |
| in | install |
| l | list, ls |
| o | offline |
| r | rm |
| s | selfupdate |
| u | u, ug, uninstall, update, upgrade, use |
| un | uninstall |
| up | update, upgrade |
| us | use |
| v | v, version |
# Currently uncovered; include to catch new upstream commands:
| a | |
| e | |
| g | |
| j | |
| k | |
| m | |
| n | |
| p | |
| q | |
| t | |
| w | |
| x | |
| y | |
| z | |
Scenario Outline: Completion for 'install'
When the user enters "install <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| an | ant |
| xyz | |
| 1. | |
| gra | gradle, grails |
| grad | gradle |
| gradk | |
# | ant 1.10. | 1.10.0, 1.10.1 | # TODO: list installable versions --> issue #4
| ant 1.10.2-mine /tm | /tmp/ |
| 'ant 1.10.2-mine /tmp ' | |
Scenario Outline: Completion for 'uninstall'
When the user enters "uninstall <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | ant, crash |
| a | ant |
| j | |
| 1. | |
| an | ant | # installed
| gr | | # none installed
| xyz | | # no such candidate
| 'an ' | | # no such candidate installed
| 'ant 1' | 1.10.1, 1.9.9 |
| 'ant 1.10.' | 1.10.1 |
| 'ant 2' | |
| 'ant 1.10.1 ' | |
Scenario Outline: Completion for 'list'
When the user enters "list <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| an | ant |
| xyz | |
| 1. | |
| 'ant ' | |
Scenario Outline: Completion for 'use'
When the user enters "use <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | ant, crash |
| an | ant |
| j | |
| 1. | |
| 'ant ' | 1.10.1, 1.9.9 |
| 'ant 1.10.1 ' | |
Scenario Outline: Completion for 'default'
When the user enters "default <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | ant, crash |
| an | ant |
| j | |
| 1. | |
| 'ant ' | 1.10.1, 1.9.9 |
| 'ant 1.10.1 ' | |
Scenario Outline: Completion for 'current'
When the user enters "current <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| an | ant | # --> installed version
| ja | java | # --> not installed
| xyz | |
| 1. | |
| 'ant ' | |
Scenario Outline: Completion for 'upgrade'
When the user enters "upgrade <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | ant, crash |
| an | ant |
| j | |
| 1. | |
| 'ant ' | |
Scenario Outline: Completion for 'offline'
When the user enters "offline <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | disable, enable |
| e | enable |
| d | disable |
| a | |
| 'enable ' | |
Scenario Outline: Completion for 'selfupdate'
When the user enters "selfupdate <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | force |
| f | force |
| a | |
| 'force ' | |
Scenario Outline: Completion for 'flush'
When the user enters "flush <cmd>" into the prompt
Then completion should propose "<completions>"
Examples:
| cmd | completions |
| | archives, broadcast, temp |
| b | broadcast |
| a | archives |
| t | temp |
| x | |
| 'temp ' | |
Scenario Outline: Completion for commands without parameters
When the user enters "<cmd>" into the prompt
Then completion should propose ""
Examples:
| cmd |
| 'version ' |
| 'version a' |
| 'broadcast ' |
| 'broadcast a' |
| 'help ' |
| 'help a' |
| 'update ' |
| 'update a' |
