Commit Message: test: add TDD bug-capture test for #1078 — container-instance missing --mount flag
Branch: tdd/m5-container-mount-flag

Background and Context

This is the TDD counterpart to bug #1078. Per the project's Test-Driven Development workflow for bugs (see CONTRIBUTING.md > Bug Fix Workflow), the first step in fixing any bug is to write a test that captures the buggy behavior. The test is tagged with @tdd_bug, @tdd_bug_1078, and @tdd_expected_fail so that it passes CI while the bug is still unfixed. Once the fix is implemented in #1078, the @tdd_expected_fail tag will be removed and the test will run normally.

See #1078 for full bug details.

Expected Behavior

A new test exists that:

Captures the exact failure described in #1078.
Is tagged with @tdd_bug, @tdd_bug_1078, and @tdd_expected_fail.
Passes CI via the expected-failure mechanism (the underlying assertion fails, confirming the bug exists, but the tag inversion causes the test to pass).
Would fail CI if the bug were fixed without removing the @tdd_expected_fail tag.

Acceptance Criteria

A test is written that captures the bug behavior described in #1078.
The test is tagged with @tdd_bug, @tdd_bug_1078, and @tdd_expected_fail.
The @tdd_expected_fail tag causes the test to pass CI (the underlying assertion fails as expected, proving the bug exists).
The test is specific enough that it will pass normally (without the tag) only when the bug is genuinely fixed.
Tag validation rules pass: @tdd_bug_1078 has corresponding @tdd_bug, and @tdd_expected_fail has both.
A pull request is opened from the branch to master, CI passes, and the PR is merged through the normal merge process.

Definition of Done

This issue is complete when:

All subtasks below are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the test and what bug behavior it captures.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, CI passes, and the PR is merged before this issue is marked done.

Subtasks

Code: Analyze bug #1078 to identify the exact failure condition, including the inputs, state, and code path that trigger the bug.
Code: Determine the appropriate test type (Behave unit test, Robot integration test, or both) and file location for the reproducing test.
Tests (Behave): Write a Behave scenario in features/ that captures the bug. Tag the scenario with @tdd_bug, @tdd_bug_1078, and @tdd_expected_fail. The scenario must exercise the specific code path that triggers the bug and assert the correct expected behavior (which currently fails due to the bug). Name the scenario descriptively to indicate it is a bug regression test.
Tests (Robot): If the bug involves integration-level behavior, add a Robot test in robot/ with equivalent tags. If purely unit-level, mark N/A with justification. N/A — bug is purely at CLI flag recognition level, fully testable via CliRunner at the unit level.
Docs: Add a comment in the test file explaining this test captures bug #1078 and uses @tdd_expected_fail until the fix is merged.
Quality: Verify CI passes with the tagged test. Confirm the underlying assertion fails for the correct reason.
Quality: Verify tag validation rules pass.
Quality: Verify coverage >=97% via nox -s coverage_report. If coverage is <97% then review the current unit test coverage report at build/coverage.xml and use it to write new Behave based unit tests to improve code coverage.
Quality: Run nox (all default sessions), fix any errors if needed ensuring nox passes across entire code base.

Implementation Notes — Bug Analysis & Test Design

Bug #1078 Analysis

Root cause: The resource_add function in cleveragents.cli.commands.resource (at resource_add command definition) defines the following type-specific CLI flags:

--path / -p — Path for physical resources
--branch / -b — Branch for git-checkout resources
--image — Container image for container-instance resources
--description / -d — Resource description
--read-only — Mark resource as read-only

Missing: The --mount flag is not defined. The specification (docs/specification.md, Container-specific flags section) mandates:

--mount RESOURCE_OR_PATH:CONTAINER_PATH

This flag should be repeatable, accepting both resource-reference mounts (local/api-repo:/workspace) and host-path mounts with optional mode (/home/user/.ssh:/home/dev/.ssh:ro).

Code path: When resource add container-instance local/test --mount local/api-repo:/workspace is invoked, Typer/Click rejects the --mount option with "No such option: --mount" and exit code 2, before any business logic executes.

Test Design

Test type: Behave unit test (BDD) — the bug is at the CLI flag recognition level, which is unit-testable via typer.testing.CliRunner.

Files created:

features/tdd_container_mount_flag.feature — 3 scenarios tagged @tdd_expected_fail @tdd_bug @tdd_bug_1078
features/steps/tdd_container_mount_flag_steps.py — Step definitions using CliRunner

Scenarios:

Single --mount flag recognition (resource-reference format)
Multiple --mount flags on a single command (repeatable)
Host-path mount with mode suffix (/path:/container-path:ro)

Pattern: Follows the same approach as tdd_plan_apply_yes_flag (bug #932) — invoke the CLI with the flag and assert the absence of the "No such option" error and exit code 2.

Robot test: N/A — this is purely a CLI flag recognition bug, fully testable at the unit level via CliRunner. No integration-level behavior is involved until the flag is recognized.

Verification

All 3 scenarios fail at the assertion level (as expected, proving the bug exists) and are inverted to passes by the @tdd_expected_fail tag mechanism. Exit code 0 from behave confirms the test suite passes.

Self-QA Implementation Notes (Cycles 1–2)

Cycle 1

Review findings: 0C/1M/1m/4n

Major: Missing CHANGELOG.md entry — CONTRIBUTING.md requires changelog updates for every PR. No entry was present.
Minor: Scenario 2 assertion cannot distinguish repeatable from non-repeatable --mount — the assertion only checks exit_code != 2 and absence of "No such option", which would pass even if --mount were non-repeatable (Click silently overwrites).
Nits: Three identical @then assertion steps (acceptable per project convention); no rw mode scenario (acceptable for bug-capture); omitted --image flag in invocations (acceptable for focused testing); .ssh directory in test path (cosmetic).

Fixes applied:

Added CHANGELOG.md entry under ## Unreleased describing the three Behave scenarios, @tdd_expected_fail usage, and referencing both #1078 and #1099.
Added .. note:: docstring block to step_assert_multiple_mounts_recognised documenting the assertion limitation and deferring stronger assertions to the bug-fix PR for #1078.
Amended commit and force-pushed. Updated PR description with CHANGELOG mention, "Known Limitations" section, and quality gate results.

Cycle 2

Review findings: 0C/0M/2m/3n — APPROVED

Minor (informational): Scenario 2 assertion limitation acknowledged as properly documented. Duplicated assertion logic across three Then steps follows existing project convention.
Nits (informational): Feature file could use Scenario Outline (matches existing convention); synthetic .ssh path (no functional impact); tag ordering differs from CONTRIBUTING example but matches all existing TDD features.

No fixes needed — all findings were acknowledged design decisions or pre-existing patterns.

Remaining Issues

None. All blocking issues resolved. Minor findings are documented and deferred to the bug-fix PR (#1078).
