- Around line 792-799: Update the test around InitDevicesWithConfig so its
partial-failure scenario is reachable: either inject a failing NVIDIA or
Cambricon initializer that populates initErrors while allowing the other device
to be added, or revise the assertions to match validateConfig’s zero-value
NVIDIA behavior. Preserve the intended validation and initialization contracts.
- Around line 813-818: Update the test around InitDevicesWithConfig to exercise
an invalid dynamic type rather than the zero value of nvidia.NvidiaConfig. Add a
test seam for the wrapper or invoke an extracted initializer directly with a
deliberately incompatible any value, and assert it returns an error without
panicking.
- Around line 818-819: Move each InitDevicesWithConfig call inside its
corresponding assert.NotPanics closure so initialization panics are captured;
assign the returned error within the closure, then assert that error afterward.
Apply this to the occurrences around the existing test cases, including the
additional locations noted in the review.
- Around line 824-831: Update the InitDevicesWithConfig test fixture to ensure
the NVIDIA, Cambricon, Hygon, and Enflame initializers actually return the four
expected errors, using injectable failing initializers or matching the real
validation behavior. Keep the test focused on exercising initializer error
aggregation rather than exiting early on zero-value configuration validation.
- Line 808: Update the assertions in the InitDevicesWithConfig test to verify
the returned err value instead of the out-of-scope initErrors accumulator.
Replace both initErrors references, including the NVIDIA and corresponding
vendor-specific checks, while preserving the existing assert.ErrorContains
validations.
- Around line 848-856: Update the Ascend fixture passed to InitDevicesWithConfig
so VNPUs.Configs contains one non-empty but malformed ascend.VNPUConfig,
allowing validation to pass far enough for ascend.InitDevices to execute. Assert
the expected initialization result or error from that malformed configuration
while preserving the no-panic behavior.
- Line 804: Replace unsupported gotest.tools/v3/assert calls at the affected
assertions with exported assert/cmp APIs: use a supported membership comparison
for DevicesMap checks, and replace NotPanics with a local panic-capture helper
or equivalent supported assertion. Update all occurrences at the referenced test
locations while preserving the existing test expectations.

Make the partial-failure fixture reachable.
The supplied InitDevicesWithConfig implementation cannot produce the state asserted by this fixture. The NVIDIA and Cambricon wrappers return ..., nil; initErrors is populated only from non-nil initializer errors. If validateConfig rejects the zero-value NVIDIA configuration, it returns before Cambricon is added. Add an injectable failing initializer or test the actual validation contract.

Use assertion APIs provided by gotest.tools/v3.
assert.Contains, assert.NotContains, and assert.NotPanics are not exported by the imported gotest.tools/v3/assert package at lines 804, 806, 819, 857, and 870. Replace them with supported assert/cmp assertions or a local panic helper. The test package cannot type-check while these calls remain.

Assert the returned error instead of the local accumulator.
initErrors is declared inside InitDevicesWithConfig and is not visible here. Both references are undefined and prevent compilation. Verify aggregation through err; the existing vendor-specific assert.ErrorContains checks already use the public result.

Exercise an invalid dynamic type.
Config.NvidiaConfig is statically nvidia.NvidiaConfig, and InitDevicesWithConfig passes that value as any. The type assertion therefore succeeds for this zero value. This test covers zero-value initialization, not type-assertion safety. Add a test seam for the wrapper or test an extracted initializer directly.

Move initialization inside the panic check.
InitDevicesWithConfig executes before each assertion. Each closure only reads the already assigned err, so it cannot catch a panic from initialization. Capture err inside the panic-check closure, then assert it afterward.

Make the multiple-failure fixture reach initializer error handling.
The shown NVIDIA, Cambricon, Hygon, and Enflame wrappers return ..., nil; they do not generate the four errors asserted below. If validation rejects these zero-value configurations, initialization exits before aggregation. Use injectable failing initializers or update the test to the actual error source.

Make the Ascend fixture reach Ascend initialization.
The empty Configs slice makes validateConfig return all configurations are empty, so ascend.InitDevices never runs. Add a non-empty malformed ascend.VNPUConfig, then assert the expected result.
