# This test puts in place a dependency chain and then verifies zkg's behavior
# when the state of individual packages in that chain changes. The chain:
#
# foo -> bar (*) -> baz (>=1.0.0) -> grault (==1.0.0) -> corge (==1.0.0)

# @TEST-EXEC: bash %INPUT

# @TEST-EXEC: echo '** Install grault' >out
# @TEST-EXEC: zkg install grault >>out

# @TEST-EXEC: echo '** Unload grault' >>out
# @TEST-EXEC: zkg unload grault >>out

# @TEST-EXEC: echo '** Install foo' >>out
# @TEST-EXEC: zkg install foo >>out

# @TEST-EXEC: echo '** Unload foo' >>out
# @TEST-EXEC: zkg unload foo >>out

# @TEST-EXEC: echo '** Load foo' >>out
# @TEST-EXEC: zkg load foo >>out

# @TEST-EXEC: echo '** Unload bar' >>out
# @TEST-EXEC: zkg unload bar>>out

# @TEST-EXEC: echo '** Remove grault' >>out
# @TEST-EXEC: zkg remove grault >>out
