+# DeleteUsers Tests
+
+All the tests data for deleteUsers are to be present in __tests__/data/deleteUsers/${destination}/
+
+### Files and their significance
+  - __`handler_input.json`__ - Input data for  `handleDeletionOfUsers` function in `versionedRouter.js`(alias for `_deleteUsers_proxy_input.json`)
+  - __`handler_output.json`__ - Output of `handleDeletionOfUsers` function in `versionedRouter.js`(alias for `_deleteUsers_proxy_output.json`)
+  - __`nw_client_data.json`__ - the mock http responses(An example can be seen in the case of `ga`)
+
+### Fields in new files
+
+#### nw_client_data.json
+
+- Type: Array<Array<object>>
+- The array of object is how many responses have to be sent back
+- Each of the object contains below mentioned fields
+   - type:
+     - Indicates what type of http client invocation it is
+     - Recommended to be sent
+     - Supported values: 
+       - post
+       - get
+       - delete
+       - constructor
+     - if nothing is mentioned, `post` is considered by default
+   - reqParams:
+     - Type: Array<any>
+     - Optional
+     - Indicates the expected arguments that are to be sent to the http client instance
+     - We would `recommend` to also add this as part of your `nw_client_data.json`
+   - response:
+     - Type: object
+     - Required
+     - The response that needs to be returned from the http client
