tape-schema

Schema validation for node.js inside tape test harness.

• compare javascript object to a schema
• combine schemas to make testing more consistent
• pinpoint error, even in deeply nested objects
• powerful any function provides flexibility
• validate missing schema definition, error if an object contains more data than schema
