Subject: [PATCH] Adds openapi v3.0.3 unit test spec, includes test cases,
 autogenerates model tests with them (#12619)

* Adds draft6 tests and python file reader

* Adds processing of multiple files

* Moves test examples into a different component so component schemas can be booleans

* Excludes boolean schema cases and some others that contain patternProperties

* Adds automatic test generation, template not quite working with indentation

* Turns on allOf tests, some failing

* Adds more generated components and tests

* Adds enum tests

* Turns on all of themissing tests

* Adds exclmax and min exclusion reasons

* Adds items test cases

* Adds maximum

* Adds maxItems

* Adds maxLength

* Adds maxProperties

* Adds minimum

* Adds minItems

* Adds minLength

* Adds minProperties

* Adds multipleOf

* Adds not

* Adds oneOf

* Adds pattern

* Adds patternProperties

* Working on properties examples, partial fix for escaped characters

* Further improves example string escaping

* Fixes properties test cases

* Adds draft6 test samples license

* Adds ref

* Finishes ref

* Adds remoteRef

* Adds required

* Improves required testing

* Fixes build error / javadoc warning

* Fixes uniqueItems bug in python-experimental

* Turns all tests back on

* Fixes 2 failing tests, all python tests pass

* Fixes java npe errors

* Fixes formatting of tests, indentation fixed

* Test fase name fixed to toTestCaseName, docstring added to ObjectWithTypeBooleans

* Fixes typo

* Adds test deletion to samples generation, samples regenerated

* Updates python-exp unit test sample, includes new ref examples

+This file ingests json schemas from

+TODO:
+- [DONE] load json file and write it into components/schemas
+- [DONE] ensure that examples are being written there
+- [DONE] add recursive casting of test examples to ObjectWithTypeBooleans
+- [DONE] move processing to defaultCodegen
+- [DONE] turn tests on
+- add endpoints with those components in:

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# unit-test-api
+sample spec for testing openapi functionality, built from json schema tests for draft6
+
+This Python package is automatically generated by the [OpenAPI Generator](https://openapi-generator.tech) project:
+
+- API version: 0.0.1
+- Package version: 1.0.0
+- Build package: org.openapitools.codegen.languages.PythonExperimentalClientCodegen
+
+## Requirements.
+
+Python &gt;&#x3D;3.9
+v3.9 is needed so one can combine classmethod and property decorators to define
+object schema properties as classes
+
+## Installation & Usage
+### pip install
+
+If the python package is hosted on a repository, you can install directly using:
+
+```sh
+pip install git+https://github.com/GIT_USER_ID/GIT_REPO_ID.git
+```
+(you may need to run `pip` with root permission: `sudo pip install git+https://github.com/GIT_USER_ID/GIT_REPO_ID.git`)
+
+Then import the package:
+```python
+import unit_test_api
+```
+
+### Setuptools
+
+Install via [Setuptools](http://pypi.python.org/pypi/setuptools).
+
+```sh
+python setup.py install --user
+```
+(or `sudo python setup.py install` to install the package for all users)
+
+Then import the package:
+```python
+import unit_test_api
+```
+
+## Getting Started
+
+Please follow the [installation procedure](#installation--usage) and then run the following:
+
+```python
+
+import time
+import unit_test_api
+from pprint import pprint
+```

+## Documentation For Authorization

+
+## Notes for Large OpenAPI documents
+If the OpenAPI document is large, imports in unit_test_api.apis and unit_test_api.models may fail with a
+RecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:
+
+Solution 1:
+Use specific imports for apis and models like:
+- `from unit_test_api.api.default_api import DefaultApi`
+- `from unit_test_api.model.pet import Pet`
+
+Solution 1:
+Before importing the package, adjust the maximum recursion limit as shown below:
+```
+import sys
+sys.setrecursionlimit(1500)
+import unit_test_api
+from unit_test_api.apis import *
+from unit_test_api.models import *
+```

+    :param host: Base url
+    :param api_key: Dict to store API key(s).
+      Each entry in the dict specifies an API key.
+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is the API key secret.
+    :param api_key_prefix: Dict to store API prefix (e.g. Bearer)
+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is an API key prefix when generating the auth data.
+    :param username: Username for HTTP basic authentication
+    :param password: Password for HTTP basic authentication
+    :param discard_unknown_keys: Boolean value indicating whether to discard
+      unknown properties. A server may send a response that includes additional
+      properties that are not known by the client in the following scenarios:
+      1. The OpenAPI document is incomplete, i.e. it does not match the server
+         implementation.
+      2. The client was generated using an older version of the OpenAPI document
+         and the server has been upgraded since then.
+      If a schema in the OpenAPI document defines the additionalProperties attribute,
+      then all undeclared properties received by the server are injected into the
+      additional properties map. In that case, there are undeclared properties, and
+      nothing to discard.
+    :param disabled_client_side_validations (string): Comma-separated list of
+      JSON schema validation keywords to disable JSON schema structural validation
+      rules. The following keywords may be specified: multipleOf, maximum,
+      exclusiveMaximum, minimum, exclusiveMinimum, maxLength, minLength, pattern,
+      maxItems, minItems.
+      By default, the validation is performed for data generated locally by the client
+      and data received from the server, independent of any validation performed by
+      the server side. If the input data does not satisfy the JSON schema validation
+      rules specified in the OpenAPI document, an exception is raised.
+      If disabled_client_side_validations is set, structural validation is
+      disabled. This can be useful to troubleshoot data validation problem, such as
+      when the OpenAPI document validation rules do not match the actual API data
+      received by the server.
+    :param server_index: Index to servers configuration.
+    :param server_variables: Mapping with string values to replace variables in
+      templated server configuration. The validation of enums is performed for
+      variables with defined enum values before.
+    :param server_operation_index: Mapping from operation ID to an index to server
+      configuration.
+    :param server_operation_variables: Mapping from operation ID to a mapping with
+      string values to replace variables in templated server configuration.
