While this initial implementation is a very simple wrapper function, implementing this in the helper/resource package provides some downstream benefits:
* Provides a standard interface for plugin developers to enable parallel acceptance testing
* Existing plugins can simply convert resource.Test to resource.ParallelTest references (as appropriate) to enable the functionality, rather than worrying about additional line(s) to each acceptance test function or TestCase
* Potential enhancements to ParallelTest (e.g. adding an environment variable to skip enabling the behavior) are consistently propagated
This adds the Taint field to the acceptance testing framework, allowing
the ability to pre-taint resources at the beginning of a particular
TestStep. This can be useful for when an explicit ForceNew is required
for a specific resource for troubleshooting things like diff mismatches,
etc.
The field accepts resource addresses as a list of strings. To keep
things simple for the time being, only addresses in the root module are
accepted. If we ever want to expand this past that, I'd be almost
inclined to add some facilities to the core terraform package to help
translate actual module resource addresses (ie:
module.foo.module.bar.some_resource.baz) into the correct state, versus
the current convention in some acceptance testing facilities that take
the module address as a list of strings (ie: []string{"root", "foo",
"bar"}).
This is rarely needed, but sometimes tests need to create temporary files as part of their operation. This should be used sparingly, since it prevents the pro-active cleanup of the temporary working directory.
Looks like while we were checking errors correctly when ExpectError was
set, we weren't checking for the *absence* of an error, which is should
be checked as well (no error is still not the error we are looking for).
Added a few more tests for ExpectError as well.
Validation is the best time to return detailed diagnostics
to the user since we're much more likely to have source
location information, etc than we are in later operations.
This change doesn't actually add any detail to the messages
yet, but it changes the interface so that we can gradually
introduce more detailed diagnostics over time.
While here there are some minor adjustments to some of the
messages to improve their consistency with terminology we
use elsewhere.
Update the command package to use the new module storage. Move the old
command output strings into the module storage itself. This could be
moved back later either by using ui callbacks, or designing a module
storage interface once we know what the final requirements will look
like.
Add an ImportStateIdFunc field to the ImportState testing functionality.
This will allow for more powerful generation of complex import state IDs
that can't be accomplished by ImportStateId or ImportStateIdPrefix
themselves.
Provider import tests previously didn't have to supply a config, but
terraform now requires the provider to be declared for discovery.
testProviderConfig returns a stub config with provider blocks based
on the TestCase Providers. This allows basic import tests in providers
to remain unchanged.
The timestamp prefix added in #8249 was removed in #10152 to ensure that
returned IDs really are properly ordered. However, this meant that IDs were no
longer ordered over multiple invocations of terraform, which was the main
motivation for adding the timestamp in the first place. This commit does a
hybrid: timestamp-plus-incrementing-counter instead of just incrementing counter
or timestamp-plus-random.
Rather than providing an already-resolved map of plugins to core, we now
provide a "provider resolver" which knows how to resolve a set of provider
dependencies, to be determined later, and produce that map.
This requires the context to be instantiated in a different way, so this
very noisy diff is a mostly-mechanical update of all of the existing
places where contexts get created for testing, using some adapted versions
of the pre-existing utilities for passing in mock providers.
Previously having a config was mutually exclusive with running an import,
but we need to provide a config so that the provider is declared, or else
we can't actually complete the import in the future world where providers
are installed dynamically based on their declarations.
* provider/aws: Add Sweeper setup, Sweepers for DB Option Group, Key Pair
* provider/google: Add sweeper for any leaked databases
* more recursion and added LC sweeper, to test out the Dependency path
* implement a dependency example
* implement sweep-run flag to filter runs
* stub a test for TestMain
* test for multiple -sweep-run list
A couple tests require lowering the grace period to keep the test from
taking the full 30s timeout.
The Retry_hang test also needed to be removed from the Parallel group,
becuase it modifies the global refreshGracePeriod variable.
Refresh calls may have side effects that need to be recorded if it
succeeds, especially common when when WaitForState is called from
resource.Retry.
If the WaitForState timeout is reached and there is a Refresh call
in-flight, wait up to refreshGracePeriod (set to 30s) for it to
complete.
This test unfortunately relies on the timing of the loops in
WaitForState, and the text of the error message. Adjust the timing so
the timeout isn't an even multiple of the poll interval, and make sure
we reach a minimum number of retries.
Make sure that we can cancel the WaitForState refresh loop when reaching
a timeout, otherwise it may run indefinitely. There's no need to try and
store and read the Result concurrently, just pass the value over a
channel.
Adds the `ImportStateIdPrefix` field for import acceptance tests. There are (albeit fairly rare) import cases where a resource needs to be imported with a combination of the resource's ID and a known string prefix. This allows the developer to specify the known prefix, and omit the `ImportStateId` field.

Sometimes when waiting on a target state, the set of valid states
through which a value will transition is unknown. This commit adds
support for an empty Pending slice and will treat any states that are not
the target as valid provided the timeouts are not exceeded.
the terraform package doesn't know about TestProvider, so don't put the
hooks in terraform.MockResourceProvider. Wrap the mock in the test where
we need to check the TestProvider functionality.
Call all ResourceProviderFactories and reset the providers before tests.
Store the provider and/or the error in a fixed factory function to be
returned again later.
Before this patch it was not possible to test for a key in a map where
the value is an empty string. With this patch, however, it is now
possible to write a check like:
```
resource.TestCheckResourceAttr("res.name", "mymap.KeyWithEmptyValue", ""),
```
To test that `KeyWithEmptyValue` is a valid key in `mymap`.
UniqueId attempted to provide an ordered unique id by using a nanosecond
timestamp, but doesn't take into account that time is not monotonic
increasing. This provides an implementation that will always be
increasing.
