+API tester for the client-API received from swagger.
 
-# Steps
+This component helps in testing the Gateway APIs by running tests on all the APIs that the gateway exposes.
+
+The Gateway API are exposed as [Swagger](https://tdei-gateway-dev.azurewebsites.net/swagger-ui/index.html)
+
+For Seeding the initial data on tests, this component also makes use of usermanagement portal that is hosted [here](https://tdei-usermanagement-ts-stage.azurewebsites.net). The `seeder.ts` class takes care of generation of org, station, service details appropriately.
+
+The component runs by importing the generated API classes of APIs and testing each of the functions. 
+
+The API methods are autogenerated and are available in [API-Client](https://github.com/TaskarCenterAtUW/TDEI-api-client). 
+
+# Steps to run tests
 - The testing rig is currently configured based on `test-harness.json` file.
 - An example of the file is already given as `test-harness.example.json`
 - `npm i`
 - `npm run test`
 
 The above code runs the tests and generates a `test-report.html` (already included for reference)
 
+## Test harness format (json)
+The `test-harness.json` file is used for getting the credentials of the system.
+
+```json
+{
+    "seed":{
+        "baseUrl":"<base url for user management>",
+        "adminUser":"<admin username>",
+        "adminPassword":"<password for admin>"
+    },
+
+    "system":{
+        "baseUrl":"<base URL for Gateway>",
+        "username":"<producer/poc username>",
+        "password":"<password>"
+    }

 - To enhance the testing with different personas and varied systems, it is imperative that we generate
   some scripts that allow generation of users and other seed data required for testing.
