Tests needed:
Tests needed for config_install:
- Fail if cache_dir from previous run cannot be deleted
- Fail if cache_dir cannot be created from current out_dir
- transfer_type_explorers: Explorers are not transferred twice
- transfer_type_explorers: No transfer tried if there are no type_explorers
__init__():
- sets up env: __target_host
- does $require work?
- $whatever should fail if there is no global explorer directory
- emulator may only be called with __ as prefix - fail otherwise!
cleanup()
- Fail if cache_dir from previous run cannot be deleted
- Fail if cache_dir cannot be created from current out_dir
- ensure paths returned by object include dot-cdist
- ensure path of explorer of object returns correct path
filter()
- ensure logformat is changed: target host is prefixed:
LOGLEVEL: target_host: MESSAGE
config_install:
run_type_manifest() - same tests as for test_initial_manifest_*?
run_manifest() - raise exception if manifest is not existent
object_run(): ensure no object is run twice
object_run(): ensure requirements are taken into account
object_run(): check (from extern?) that all needed variables are setup
object_run(): ensure no code-{local, remote} is created, if gencode is not producing code
object_run(): ensure no code-{local, remote} contains what gencode created
run_initial_manifest():
- parameter is actually used (from __init__)
- ensure changing the manifest actually runs a different manifest
-> give ConfigInstall Constructor different manifest
-> different manifest is executed.
- test all submitted (from core to type manifest) variables:
- ENVIRONMENT
- they are set
- they contain the correct values
run_type_explorer(): ensure output is saved to correct path
run_type_explorer(): ensure a type with no explorers works
run_type_explorer(): ensure environment is setup correctly
run_type_manifest():
- test all submitted (from core to type manifest) variables:
- ENVIRONMENT
- they are set
- they contain the correct values
- same tests as for test_initial_manifest_*?
run_manifest():
- test all submitted variables:
- ENVIRONMENT
- including __debug, if debug
- they are set
- they contain the correct values
- does $require work?
- check that exception raised, if manifest is not existent
object_run():
- ensure no object is run twice
- ensure requirements are taken into account?
- and order of run is adjusted
- check (from extern?) that all needed variables are setup
- ensure no code-{local, remote} is created,
if gencode is not producing code
- ensure THAT code-{local, remote} contains what gencode created
- abort if gencode-* fails
- abort if code-* fails
- abort == raise(FooException)
- gencode-*: ensure ENVIRONMENT is setup correctly
run_type_explorer()
- ensure ALL type explores have been run
- ensure output is saved to correct path
- ensure a type with {0,1,2} explorers works ?
- none, one, multiple
- ensure ENVIRONMENT is setup correctly
- fails if ANY of the given explorer fails
run_global_explorers():
- ensure ALL type explores have been run
- ensure output is saved to correct path
- ensure a type with {0,1,2} explorers works ?
- none, one, multiple
- ensure ENVIRONMENT is setup correctly
- fails if ANY of the given explorer fails
link_emulator():
- ensure that links to ALL types are created
- ensure that links points to correct executable
- i.e. readlink() works
- AND target of readlink is the correct executable
stage_run()
- ensure that for every object in
cdist.core.Object.list_objects() is passed into
self.object_run()
- instantiate + overwrite + test
object_prepare():
- calls (in this order):
self.run_type_explorer(cdist_object)
self.run_type_manifest(cdist_object)
cdist_object.prepared = True
- object is prepared after function call
all: check that messages of all functions contain target_host in string
stage_prepare():
- calls (in this order):
self.link_emulator()
self.run_global_explorers()
self.run_initial_manifest()
- ensure that all objects are created :-)
- as defined in inital manifest + type manifests
deploy_to()
- ensure self.stage_prepare() and self.stage_run() are
run. [ORDER]
- instantiate + overwrite + test
deploy_and_cleanup()
- ensure self.deploy_to() + self.cleanup() are are run
run. [ORDER]
- instantiate + overwrite + test
transfer_object_parameter()
- check that object parameters are transferred
- paths are setup correctly
- test via mock of remote_mkdir and transfer_path
- ensure self.remote_mkdir, self.transfer_path are run. [ORDER]
- instantiate + overwrite + test
transfer_global_explorers()
- paths are setup correctly
- test via mock of self.remote_mkdir() and self.transfer_path()
- ensure self.remote_mkdir, self.transfer_path are run. [ORDER]
- instantiate + overwrite + test
transfer_type_explorers():
- Explorers are not transferred twice
- paths are setup correctly
- test via mock of self.remote_mkdir() and self.transfer_path()
- Explorers are transferred
- test via mock of self.remote_mkdir() and self.transfer_path()
remote_mkdir()
- is directory created
remove_remote_path
- is path removed
transfer_path
- is src to dst transferred?
emulator:
may only be called with __ as prefix - fail otherwise!
