UNSUPPORTED_TEST_TYPE

Error message

UNSUPPORTED_TEST_TYPE

What it means

The ModelScope adapter's getTestImageRequest only supports specific test types (e.g. simple t2i prompts). When asked for a test request of an unrecognized testType, it throws UNSUPPORTED_TEST_TYPE with the offending testType in metadata.

Solutions

1. Pass one of the supported test types (text-to-image) for ModelScope models
2. Guard the test call with a capability check before requesting the test
3. File an adapter feature request if i2i testing is needed

const SUPPORTED = new Set(['text2image' /* adapter's supported types */])
if (!SUPPORTED.has(testType)) skipTest(modelScopeModel)

function isSupportedTestType(t: string): boolean { return ['text2image'].includes(t) }

if (!isSupportedTestType(testType)) return { skipped: true }
await adapter.getTestImageRequest(testType)

When it happens

Trigger: Invoking the adapter's model-test feature with a testType other than the supported values — e.g. a UI-driven 'image2image' or 'edit' connectivity test on a ModelScope image model.

Common situations: A generic test-runner UI that enumerates all test types across adapters and passes unsupported ones to ModelScope; new test types added elsewhere but not implemented here.
