Check Test Coverage

Check Test Coverage

Analyze which oc-mirror CLI features are tested at the integration and e2e levels, and which have gaps.

Step-by-step process

1. Discover CLI features

Run these commands to enumerate all subcommands and flags:

oc-mirror --v2 --help
oc-mirror --v2 delete --help
oc-mirror --v2 list operators --help
oc-mirror --v2 list releases --help
oc-mirror --v2 version --help

If oc-mirror is not in PATH, build it first with make build and use ./bin/oc-mirror.

From the output, extract:

• Workflows: mirrorToMirror (m2m), mirrorToDisk (m2d), diskToMirror (d2m)
• Subcommands: delete, list operators, list releases, version
• Flags: every flag from each subcommand's help output (skip hidden/deprecated flags unless they appear in tests)

2. Parse integration tests

Read all *_test.go files in tests/integration/. For each file, extract:

• Ginkgo Describe, Context, and It block labels
• Flags and workflows referenced in the test body (e.g., --dry-run, --delete-id, --from)
• Helper function calls that exercise specific features

Build a map of feature -> test file + test label.

3. Parse e2e tests

Read test files in tests/e2e/test/e2e/ (primarily oc_mirror_v2.go). Extract:

• Test case descriptions and case IDs
• Workflows and flags exercised in each case
• Test data configs referenced from tests/e2e/test/e2e/testdata/

4. Cross-reference and classify

For each CLI feature (subcommand, flag, workflow), classify coverage:

| Level | Meaning |

|-------|---------|

| Covered | Tested at integration and/or e2e level with meaningful assertions |

| Partially covered | Only happy path, or tested at only one level when both would be appropriate |

| Not covered | No test exercises this feature |

Consider a feature "partially covered" if:

• It's only tested in the happy path but has error handling worth verifying
• It's a flag that modifies behavior but is only tested implicitly (e.g., the flag is set but its effect isn't asserted)

5. Produce the report

Present results in this format:

Summary table

| Feature / Flag       | Integration | E2E  | Status           |
|----------------------|-------------|------|------------------|
| m2m workflow         | m2m_test.go | 73359| Covered          |
| --dry-run            | dry_run_... | -    | Partially covered|
| --secure-policy      | -           | -    | Not covered      |
| ...                  |             |      |                  |

Priority gaps

List the top uncovered or partially covered features, ordered by importance:

• Features that affect data correctness (e.g., signature verification, archive integrity)
• Features that affect user-facing behavior (e.g., filtering, error codes)
• Features that are operational concerns (e.g., parallelism, profiling)

For each gap, recommend:

• Which test level is appropriate (integration vs. e2e)
• A one-line description of what the test should verify

6. Optional: compare with previous run

If a previous coverage report exists in the conversation history, highlight what changed: new tests added, features that moved from "not covered" to "covered", and any regressions.
