Takehome test

Program Requirements

• Built in Go with one HTTP POST route
• Receive a listing of orders in XML (described in the example below)
• Process each record concurrently with goroutines (convert the "data" field in each Order to be uppercase)
• Return data in JSON (described in the example below)
• The service does all work in-memory and does not need to persist data
• The service calls should be blocking

Full Example

​

Input Example (input_example.xml):

<orderList>	
	<order>
		<id>aeffb38f-a1a0-48e7-b7a8-2621a2678534</id>
		<data>first_Order_Data</data>
		<createdAt>0001-01-01T00:00:00Z</createdAt>
		<updatedAt>0001-01-01T00:00:00Z</updatedAt>
	</order>
	<order>
		<id>beffb38f-b1a0-58e7-c7a8-3621a2678534</id>
		<data>second_Order_Data</data>
		<createdAt>0001-01-01T00:00:00Z</createdAt>
		<updatedAt>0001-01-01T00:00:00Z</updatedAt>
	</order>
<orderList>

Example Request:

​ curl -X POST <YOUR_JSON_SERVER>:8080/process -d @input_example.xml ​

Example Response:

{
	"orderList": [
		{
			"id": "aeffb38f-a1a0-48e7-b7a8-2621a2678534",
			"data": "FIRST_ORDER_DATA",
			"createdAt": "0001-01-01T00:00:00Z",
			"updatedAt": "0001-01-01T00:00:00Z"
		},
		{

			"updatedAt": "0001-01-01T00:00:00Z"
		}
	]
}

How to test

• Go tests (run unit tests without spawning the server): go test
• Bash tests (spawn server and test valid request): ./RUNME.sh

How to run

go run main.go

Some Notes

• I changed the output format because the given format wasn't valid JSON.
• Using channels wasn't required as each goroutine edited the Order objects in-memory, lowering system requirements.
• There were no specifications about how to handle data validation errors.
