Merge Risk: 🟡 Moderate · up to This PR adds Bazel-based Cucumber test infrastructure for the flagd provider. Recent commits claim to address configuration pattern matching and prior review feedback, but verification against the current code shows three known gaps remain: fatal-status-code test scenarios can pass without truly validating the configured codes, cache-related test scenarios don't actually exercise caching behavior, and the build pulls two dependencies from mutable Git tags that could change without notice, risking non-reproducible test builds. These are confined to test infrastructure rather than production runtime, but should be resolved or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

Inline comments:
In `@MODULE.bazel`:
- Line 50: Update both git_repository dependency declarations in MODULE.bazel to
use immutable commit hashes: replace tag 2.9 with
ec4dbcf23fcae77db411a13d9f1183c5dc24d5ae and tag v3.8.0 with
7575a1dc45f176e57e809748a712a555e9aa5d11.
- Around line 64-66: Restrict gherkin_test and its flagd_binary dependency to
the Linux x86_64 platform, using the repository’s existing Bazel
platform-constraint mechanism. Ensure the test cannot resolve or execute the
flagd_linux_x86_64 archive on other operating systems or CPU architectures.
In `@providers/flagd/tests/gherkin/BUILD`:
- Around line 57-59: Once the Gherkin scenarios pass, remove the "manual" tag
from the gherkin_test configuration so it is included by the GitHub Actions
bazel test //providers/... wildcard; retain the tag until that condition is met.
In `@providers/flagd/tests/gherkin/steps/config_steps.cpp`:
- Around line 16-17: Update the environment setup and CleanupEnv flow around
g_state.set_env_vars to capture each variable’s original value before the first
overwrite, then restore that value during cleanup instead of unconditionally
calling unsetenv; preserve unset behavior for variables that were initially
absent.
- Around line 136-142: Update TheOptionOfTypeShouldHaveValue to handle
fatalStatusCodes by asserting the expected value against
FlagdProviderConfig::GetFatalStatusCodes(), and add a final failure path for any
unsupported option name after the existing branches.
In `@providers/flagd/tests/gherkin/steps/evaluation_steps.cpp`:
- Line 99: Update the assertion step parsing around the int64 and floating-point
conversions at the referenced locations, including the steps using std::stoll
and std::stod. Use checked parsing helpers that catch conversion errors, fail
the assertion immediately with a clear message, and avoid allowing exceptions to
escape the noexcept test runner before output comparison.
In `@providers/flagd/tests/gherkin/steps/provider_steps.cpp`:
- Around line 22-25: Update InitializeProvider and FlagdProviderConfig to handle
the configured cache option before reusing or creating a provider: add cache
configuration support and include it in the stable-provider reuse key,
preserving reuse only when selector and cache settings match; alternatively,
explicitly reject unsupported cache options.
In `@providers/flagd/tests/gherkin/steps/step_utils.cpp`:
- Around line 113-118: Update ValueToJson’s numeric conversion to preserve the
stored numeric type without using AsInt() as a type check, which rounds
floating-point values such as 3.14; return integral values as integers and
floating-point values as doubles so JSON object assertions retain the original
number.
In `@providers/flagd/tests/gherkin/test_env.cpp`:
- Around line 298-302: The merged flag-file write using std::ofstream and dest
must validate both opening and writing succeeded; on failure, emit the
surrounding code’s CRITICAL message and exit consistently with comparable setup
failures, rather than continuing with an empty or truncated all_flags.json.

Nitpick comments:
In `@providers/flagd/tests/gherkin/test_env.h`:
- Line 44: Add <sys/types.h> to test_env.h so the pid_t declaration used by pid_
is available when the header is included independently.

Inline comments:
In `@providers/flagd/tests/gherkin/steps/config_steps.cpp`:
- Around line 163-165: Update the resolver selection logic to assign "file"
whenever has_offline_path is true, including when the current resolver is the
default "rpc"; preserve the existing behavior for sources without an offline
path and ensure the scenario state records the file resolver.
In `@providers/flagd/tests/gherkin/steps/evaluation_steps.cpp`:
- Around line 214-215: Update the integer metadata assertion in the evaluation
step to reject floating-point values with fractional parts instead of truncating
them during the cast. Before converting the value from var_val, require it to be
integral and within int64_t range, while preserving valid integer-valued doubles
and existing integer assertions.
