hypothesis helps you write and maintain property-based tests in your Python project.

       hypothesiscodemod  refactors  deprecated  or  inefficient  code,  rewriting  files in place.  It has no
       additional options.

       hypothesiswrite writes property-based tests for you. Type annotations are helpful but not required.  The
       following options are recognized:

       --roundtrip
              write roundtrip tests for write/read or encode/decode functions.

              Example: hypothesiswrite--roundtripjson.dumpsjson.loads--equivalent
              write tests whether two functions behave identically.

              Example: hypothesiswrite--equivalentast.literal_evaleval--errors-equivalent
              like --equivalent, but also allows consistent errors.

       --idempotent
              write tests whether a function is idempotent.

       --binary-op
              write tests for associativity, commutativity and identitiy element.

              Example: hypothesiswrite--binary-opoperator.add--exceptCLASS
              dotted name of exception to ignore. can be specified multiple times.

       --annotate, --no-annotate
              force tests to be type-annotated (or not).

       --style=STYLE
              write tests as pytest functions or unittest methods.
