# Postman Collection
This directory contains the Postman collection for all Hyperswitch supported connectors and this documentation talks about how to build the collection.
## Development of collections
### Prerequisites
- [Postman](https://www.postman.com/downloads/)
- Newman CLI fork from npm: npm install -g 'https://github.com/knutties/newman.git#feature/newman-dir'
### Steps to build the collection
- `stripe.postman_collection.json` is the most up-to-date collection that consists of all the features that Hyperswitch supports
- It is recommended that you use the `stripe.postman_collection.json` as the base collection to build the collection for other connectors
- If you developed a new feature, make sure you add them to the `stripe.postman_collection.json` given that it is a core feature. If it is collection specific, add it to the respective collection
---
- The collection consists of many directories and each directory consists of a set of requests. Each directory is a feature and each request is a test case
- The directory name should be the name of the feature and the request name should be the name of the test case
- If the feature that you add is a flow test case, make sure you add the test case to the `Flow Testcases` directory. If you did a refactor that handles errors say, expiry date of a card, make sure you add the test case to the `Variation Cases` directory prefixed by `Scenario-<number>` where `<number>` is the number of the scenario
- If the feature that you add is a core feature, make sure you add the test case to the `Happy Cases` directory where only the happy cases are tested.
---
- Make sure that you update the `tests` section where the necessary `javascript` code has to written/updated to test the feature (assertion checks where you verify the results obtained with the expected outcome)
- If certain `tests` need to be run at the time of making a request, make sure you add them to the `Pre-request Script` section of the request
- Make sure that the request body does not contain any comments else the `newman dir-export` command will fail which is used to export the collection to its directory structure
---
- After all the development is done, make sure you right click and run the collection in respective environments to make sure that the collection runs successfully
- Export the collection as `v2.1` and save it `postman/collection-json` directory with file name following the format `<connector_name>.postman_collection.json`
- Export the postman-collection to its directory structure by using the command `newman dir-export /path/to/collection.json` and move the folder to `postman/collection-dir` (for more info, refer to [Newman-Fork](/crates/test_utils/README.md#newman)) with the folder renamed with name of the connector
- You can run the postman collection from directory structure by referring [here](/crates/test_utils/README.md#running-tests)
