# TESTING
# QA team test cases. Test code exists but were these based on a list of steps required to produce a result?
# Are there any real-world users of Unleash who are happy to read and test the Open API specification and make suggestions for improvement? Would they be happy to screen-record what they are doing (how they use the API will give invaluable insights)?
# Ideally, you'd want developers using Java, Node.js, Go, Ruby, Python and .Net to test
# Could there be a simple sample app that implemented all API calls (using realistic scenarios)? Might just be a consolidated version of the tests/e2e code with some triggers (buttons) and some UI to display outcomes.
# OAS REVIEW
# Move responses to root responses section in components (from schema section)
# Issues with rendering as nested externaldocs from Swagger UI. See GET /admin/feature-types. Not an issue in other tools (see redoc.html)
# Other candidates for $ref: createdAt, lastSeen/updatedAt, instanceId, appName/appNamePath, sdkVersion, feature toggle type titles, enabled, stale, weight
# STYLE
# Add style guide MD. UK/US = US, Newspaper/Movie, Plurals. &. What 's the closest match for Unleash? http://apistylebook.com/design/guidelines/
# OAS styler - Only use backticks for code samples and API paths. Use bold for schema items and italic for schema item settings

    Unleash is an open source feature flag and toggle system for all your applications and services.

    # Try it out

    ## Try it in your browser

    Once you have [set your Unleash server up](https://unleash.github.io/docs/getting_started), you can test the API from inside your browser. The following assumes the server is running on localhost:4242.

    The following 'endpoints' (such as `GET /admin/metrics/applications`) provide reference documentation for the Unleash REST API. To try out API calls:
    1. Navigate to an endpoint
    2. Click **Try it out** - in the right-hand (black) panel
    3. Customize the **Request body** and/or **Parameters**.
    4. Click **Execute**.

    You will see the cURL request submitted to the API server and the corresponding response.

    ## Try it in Postman

    Alternatively, you can test the API in [Postman](https://app.getpostman.com/run-collection/8552ddcd4cc9fc012548)

              The client SDK will summarize all variant weights, hash the number and divide the users among them. The distribution will be according to the weight as a fraction of the sum of weight.

                        The client SDK will allocate traffic to each variant based on this weighting (as a fraction of the sum of all variant weights).
                        **Examples**
                        - You have four variants, each with a weight of 1000. The SDK will distribute traffic evenly: 25% each
                        - You have two variants, one with a weight of 100 and one with a weight of 900. The SDK will send 90% of traffic to the variant with a weight of 900
