Release 3.28.1

🏎️ Performance

• Improve performance of add_link by avoiding unnecessary reference resolving.

Release 3.28.0

I am happy to announce Schemathesis 3.28 🎉

It does not include a lot of new features but instead clarifies error messages and makes Schemathesis work with more recursive references than before.

🚀 Added

• Request.deserialize_body and Response.deserialize_body helper methods to deserialize payloads to bytes from Base 64.
• Support for multipart/mixed media type.

🔧 Changed

• Do not show suggestions to show a traceback on Hypothesis' Unsatisfiable error.
• Clarify error message on unsupported recursive references.
• Report more details on some internal errors instead of "Unknown Schema Error".
• Update error message on why Schemathesis can't generate test cases for some API operations.

🐛 Fixed

• Internal error on Windows when the CLI output is redirected to a file and code samples contain non-CP1252 characters.
• Properly check for nested recursive references inside combinators. This makes Schemathesis work with more schemas with recursive references.

Release 3.27.1

🚀 Added

• GenerationConfig.headers.strategy attribute for customizing header generation. #2137
• Support for python -m schemathesis.cli. #2142
• Support for anyio>=4.0. #2081

🐛 Fixed

• Supporting non-Starlette ASGI apps. #2136
• Missing version metadata in ASGI client causing errors with ASGI3-only apps. #2136

Release 3.27.0

The new release of Schemathesis introduces important changes for ASGI & WSGI applications. Now, you can use Case.call and Case.call_and_validate to run tests directly, replacing the previous separate methods for these application types (call_asgi / call_wsgi)

🚀 Added

• Case.as_transport_kwargs method to simplify the creation of transport-specific keyword arguments for sending requests.

🔧 Changed

• Make Case.call work with ASGI & WSGI applications.
• Extend the JUnit XML report format to match CLI output including skipped tests, code samples, and more.

🗑️ Deprecated

• Case.call_wsgi & Case.call_asgi in favor of Case.call.
• Case.as_requests_kwargs & Case.as_werkzeug_kwargs in favor of Case.as_transport_kwargs.

Release 3.26.2

🚀 Added

• Support for pyrate-limiter>=3.0.

🐛 Fixed

• Excluding \x00 bytes as a result of probes.

Release 3.26.1

🚀 Added

• Store time needed to generate each test case.

🐛 Fixed

• InvalidArgument when using from_pytest_fixture with parametrized pytest fixtures and Hypothesis settings. #2115

Release 3.26.0

🚀 Added

• Support for per-media type data generators. #962
• Support for application/yaml & text/yml media types in YAMLSerializer.
• EXPERIMENTAL: Run automatic schema optimization & format inference if CLI is authenticated in Schemathesis.io.

🐛 Fixed

• Not resolving references in nested security schemes. #2073

🔧 Changed

• Improve the error message when the minimum possible example is too large.

Release 3.25.6

🐛 Fixed

• Not respecting allow_x00 and codec configs options while filling gaps in explicit examples.
• Internal error when sending multipart/form-data requests when the schema defines the */* content type.
• Internal error when YAML payload definition contains nested binary format.
• Internal error when an Open API 2.0 schema contains no swagger key and the schema version is forced.

🔧 Changed

• Indicate API probing results in CLI.

Release 3.25.5

🐛 Fixed

• Incorrect error message when the code inside the hook module raises ImportError. #2074
• Compatibility with Hypothesis >6.98.14
• Not respecting allow_x00 and codec configs options for data generation in some cases. #2072

Release 3.25.4

🔧 Changed

• Improve error message when the minimum possible example is too large.
