Shahed Nasser 58f297cc75 docs: added documentation on testing tools (#8939)
- Added documentation on how to use Medusa's tools from the `medusa-test-utils` package to create integration and unit tests.
- Added a manual reference on the `medusaIntegrationTestRunner` and `moduleIntegrationTestRunner` functions. Since the typings in the source code aren't very informative, I opted for a manual reference shedding light on the important bits.

Closes DOCS-852

In this chapter, you'll learn about the `medusaIntegrationTestRunner` utility function used to write integration tests.
## medusaIntegrationTestRunner Utility
The `medusaIntegrationTestRunner` utility function is provided by the `medusa-test-utils` package to create integration tests in your Medusa project. It runs a full Medusa application, allowing you test API routes, workflows, or other customizations.
For example:
export const highlights = [
["4", "api", "A set of utility methods used to send requests to the Medusa application."],
["4", "getContainer", "A function to retrieve the Medusa container."]
]
```ts title="integration-tests/http/test.spec.ts" highlights={highlights}
import { medusaIntegrationTestRunner } from "medusa-test-utils"
medusaIntegrationTestRunner({
testSuite: ({ api, getContainer }) => {
// TODO write tests...
}
})
```
The `medusaIntegrationTestRunner` function accepts an object as a parameter. The object has a required property `testSuite`.
`testSuite`'s value is a function that defines the tests to run. The function accepts as a parameter an object that has the following properties:
- `api`: a set of utility methods used to send requests to the Medusa application. It has the following methods:
- `get`: Send a `GET` request to an API route.
- `post`: Send a `POST` request to an API route.
- `delete`: Send a `DELETE` request to an API route.
- `getContainer`: a function that retrieves the Medusa Container. Use the `getContainer().resolve` method to resolve resources from the Medusa Container.
The tests in the `testSuite` function are written using [Jest](https://jestjs.io/).
### Other Options and Inputs
Refer to [this reference in the Learning Resources documentation](!resources!/test-tools-reference/medusaIntegrationTestRunner) for other available parameter options and inputs of the `testSuite` function.
---
## Database Used in Tests
The `medusaIntegrationTestRunner` function creates a database with a random name before running the tests. Then, it drops that database after all the tests end.
To manage that database, such as changing its name or perform operations on it in your tests, refer to the [references in the Learning Resources documentation](!resources!/test-tools-reference/medusaIntegrationTestRunner).

## Example Integration Tests
The next chapters provide examples of writing integration tests for API routes and workflows.
