+## Newman Usage
 
-- Make sure you that you've the postman collection for the connector available in the `postman` dir with the name `<connector_name>.postman_collection.json`
+- Make sure you that you've _**do not**_ have the official newman installed but rather the `newman` fork with directory support
+  - `newman` can be installed by running `npm install -g 'https://github.com/knutties/newman.git#feature/newman-dir'`
+  - To see the features that the fork of `newman` supports,  click [_**here**_](https://github.com/knutties/newman/blob/feature/newman-dir/DIR_COMMANDS.md)
 - Add the connector credentials to the `connector_auth.toml` / `auth.toml`
-- In terminal, execute:
-  ```zsh
+- Export the auth file path as an environment variable:
+  ```shell
   export CONNECTOR_AUTH_FILE_PATH=/path/to/auth.toml
+  ```
+- Run the tests:
+  ```shell
   cargo run --package test_utils --bin test_utils -- --connector_name=<connector_name> --base_url=<base_url> --admin_api_key=<admin_api_key>
   ```
+
+**Note:** You can optionally pass `--verbose` to see the logs of the tests. But make sure you that passing `--verbose` will also print the API-Keys in the logs. So, make sure you don't push the logs to any public repository. Below is an example:
+```shell
+cargo run --package test_utils --bin test_utils -- --connector_name=<connector_name> --base_url=<base_url> --admin_api_key=<admin_api_key> --verbose
+```
+
+### Running newman locally
+
+Execute the following commands:
+```shell
+export CONNECTOR_AUTH_FILE_PATH=/path/to/auth.toml
+cargo run --package test_utils --bin test_utils -- --connector_name=<connector_name> --base_url=http://127.0.0.1:8080 --admin_api_key=test_admin
+# Optionally, you can add `--verbose` in the end
+```
+## UI tests
+
+To run the UI tests, run the following command:
+```shell
+cargo test --package test_utils --test connectors -- <connector_ui_name>::<optionally_name_of_specific_function_run> --test-threads=1
+```
+### Example
+
+Below is an example to run UI test to only run the `GooglePay` payment test for `adyen` connector:
+```shell
+cargo test --package test_utils --test connectors -- adyen_uk_ui::should_make_gpay_payment_test --test-threads=1
+```
+
+Below is an example to run all the UI tests for `adyen` connector:
+```shell
+cargo test --package test_utils --test connectors -- adyen_uk_ui:: --test-threads=1
+```
