schemathesis 4.25.1

Release 4.25.1

on Python PyPI

🚀 Added

• Support for validating httpx2 responses in Case.validate_response.

🔧 Changed

• Suggest the server URL declared in the schema when the missing base_url error fires.
• Mention warnings.fail-on in the --warnings help text.

🐛 Fixed

Coverage phase

• Keeping false for const: 0 (and vice versa) when intersecting allowed values.
• Emitting branch values that ignore a sibling anyOf/oneOf/allOf or the keywords beside them.
• Emitting objects without a name one allOf branch requires and another forbids.
• Duplicate positive cases for schemas combining anyOf/oneOf with keywords beside them.
• Emitting a property's const that the rest of its schema rejects.
• Emitting a oneOf value a second branch admits under the operation's draft.
• Emitting enum/const members the operation's draft rejects.
• Emitting example/default values the operation's draft rejects.
• Judging anyOf/oneOf branch values against the parent in the wrong draft.
• Crashing on multipleOf beside a numeric bound past 28 significant digits.
• Emitting multipleOf steps no float can carry, landing back on the excluded bound.
• Numeric exclusiveMinimum/exclusiveMaximum overriding a tighter minimum/maximum instead of combining.
• Integer boundary values emitted as floats when the bound is written like 7.0.
• Integer steps past float bounds taken in binary, not the decimal the validator reads.
• Emitting an excluded integer bound when minimum/maximum repeats a large float exclusiveMinimum/exclusiveMaximum.
• Emitting a float as a type violation for integer when number is allowed too.
• Emitting a non-multiple for multipleOf past 2^53.
• Emitting inf as a violation of a bound at the largest float.
• Generating non-integer values for integers with a fractional multipleOf.
• Dropping every value of a type when another type's container template cannot be built.
• Ignoring additionalProperties for required names absent from properties.
• Exceeding maxProperties when covering a property the template omits.
• Emitting an optional object property whose schema requires a name it forbids.
• Emitting a non-object as a minProperties violation for untyped schemas.
• Dropping properties named if, then, else, or not from nested templates.
• Generating no positive cases for objects with an ungeneratable property.
• Crashing on a pattern whose minLength exceeds the generation buffer.
• Emitting values for strings, alone or as properties, whose minLength exceeds maxLength.
• Omitting string parameters with a very large maxLength.
• Crashing on a pattern whose minLength exceeds maxLength.
• Crashing on a minItems/minProperties past the generation buffer beside a combinator.
• Filling a large minItems/minProperties floor past a smaller ceiling.
• Hanging on a maxProperties past the generation buffer.
• Crashing on a large minItems without items, and building arrays past the generation buffer.
• Crashing on a minProperties past the generation buffer.
• Spending a minute on a minProperties in the hundreds and then emitting nothing.
• Sending empty array and object path parameters that blank the path segment.
• Repeating requests when different generated values serialize identically.
• Ignoring header and cookie example/default values with non-alphanumeric characters.
• Skipping body examples that name a readOnly field.
• Reusing generated values across operations whose $ref targets differ.

False positives

• positive_data_acceptance for values with a sibling anyOf/oneOf in the coverage phase.
• negative_data_rejection for format: float bounds a single-precision server cannot distinguish.
• negative_data_rejection for numeric bounds past 2^53 in the coverage phase.
• negative_data_rejection for bodies whose schema declares a format anywhere.

Others

• Report a minItems/minProperties past the generation buffer as a schema error instead of a health check.
• Non-body parameters with anyOf/oneOf/$ref schemas losing their null branch to the default string type.
• Object values for query parameters declared with anyOf/oneOf serialized as their property names.
