Description of your changes

Note

Stacked on #487, so until it merges, this PR's diff includes it. The commits for this PR are the top five.

This is the follow-up to two of @haarchri's comments on #486. All the simulate integration cases lived in cmd/crossplane/project. Now each command owns its suite, and the simulate.ProjectResult type is renamed to fit what it is.

Suites per command:

  • cmd/crossplane/composition: TestCompDiffIntegration and the fixtures only it uses.
  • cmd/crossplane/xr: TestDiffIntegration and the fixtures only it uses.
  • cmd/crossplane/project: keeps the project simulate cases, the plan-output and provider-plan tests.
  • Shared harness: internal/testutils/integration/simharness, behind the integration build tag. It holds the argv translation, the run helpers, the case types and the least-privilege RBAC rules.
  • Shared fixtures: the CRDs and every fixture more than one suite uses are in internal/testutils/integration/testdata.

Files moved with git mv, so git log --follow keeps their history. No case is added, removed or changed. The test list across the three packages matches the one before the move.

-p 1 for the integration tests: once the cases were split into three packages, go test ran them in parallel, and three suites rendering through Docker at once timed out. nix/apps.nix now runs integration packages one at a time, and each package's cases still run in parallel. Before the move, the simulate cases were all in one package, so CI's integration job should take about as long as before.

ProjectResult becomes Result: every simulate command emits it for -o json and -o yaml, not only project simulate. NewProjectResult becomes NewResult. The JSON output is unchanged.

I have:

  • Read and followed Crossplane's contribution process.
  • Run ./nix.sh flake check to ensure this PR is ready for review.
  • Added or updated unit tests. A pure move and rename.
  • Linked a PR or a docs tracking issue to document this change. No user-facing change.
  • Added backport release-x.y labels to auto-backport this PR.

feat(diff): restore the XR-only diff path
ef0875e 
Restore PerformDiff with its input validator, ValidatedInput, the
WithInputValidatorFactory option, their mocks, test helpers and tests
from the state before the XR-only path was removed. Keep the
TestManagedByManagerWithNoName case that the managedBy/boundToClaim
table port added and the restored tests lack.

feat(simulate): classify composite resources and claims for xr simulate
8f1d2d8 
Inputs that are neither Compositions nor project files are composite
resource candidates, which checkComposites confirms against the
cluster's XRDs. Every rejection uses RejectInput's template, so
composition and xr simulate point at each other symmetrically. The
runner gains a Composites input that runs PerformDiff and renders
through renderXRReport.

feat(xr): add xr simulate
c4e0dc0 
xr simulate previews composite resource or claim files against the
cluster with its Compositions and functions, through the shared
simulate runner. It takes no selection flags or --max-concurrency.

test(xr): restore the xr simulate integration tests
c3c77f3 
Restore TestDiffIntegration, TestSimulateProviderPlan, the XR plan-output
cases of TestSimulatePlanOutput and the remaining testdata. The harness
now runs XRDiffTest cases as `xr simulate` with -f per file, and the
TestCompDiffIntegration comments that point at TestDiffIntegration are
restored.

test(xr): restore the XR-only integration harness code
cf0e562 
Restore simArgs.FunctionCredentials with its --function-credentials argv,
which the XR cases of TestDiffIntegration use. simulateArgv maps
XRDiffTest to xr simulate and still fails on any other unknown test type.
The admission-policy gate uses integration.AwaitAdmissionDenial.
