Multipart and GraphQL

hitspec provides dedicated block syntax for multipart form data and GraphQL requests, so you do not need to manually construct complex request bodies.

Multipart Form Data

Use the >>>multipart block to send multipart/form-data requests. This is the standard format for file uploads and mixed form submissions.

### Upload a profile photo
# @name uploadPhoto

POST {{baseUrl}}/upload

>>>multipart
field name = John Doe
field email = john@example.com
file @./photo.jpg
<<<

>>>
expect status 200
expect body.uploaded == true
<<<

The Content-Type: multipart/form-data header is set automatically. Do not set it manually.

Field Syntax

Each line in a >>>multipart block is either a field or a file:

Type	Syntax	Description
Text field	`field name = value`	Sends a form text field
File upload	`file @./path/to/file`	Uploads a file from disk

Multiple Fields and Files

You can include any combination of fields and files:

### Submit a report with attachments
# @name submitReport

POST {{baseUrl}}/reports

>>>multipart
field title = Monthly Report
field department = Engineering
field priority = high
file @./report.pdf
file @./data.csv
<<<

>>>
expect status 201
expect body.id exists
<<<

Variable Interpolation

Variables are resolved in both field values and file paths:

>>>multipart
field name = {{userName}}
field token = {{authToken}}
file @{{uploadPath}}
<<<

File paths in file @ directives are relative to the .http file location.

GraphQL

Use the >>>graphql block to write GraphQL queries and mutations. Optionally add a >>>variables block for query variables.

Basic Query

### Get all users
# @name getUsers

POST {{baseUrl}}/graphql
Content-Type: application/json

>>>graphql
query {
  users {
    id
    name
    email
  }
}
<<<

>>>
expect status 200
expect body.data.users type array
expect body.errors !exists
<<<

Query with Variables

Use the >>>variables block to pass variables to your GraphQL query:

### Get user by ID
# @name getUser

POST {{baseUrl}}/graphql
Content-Type: application/json

>>>graphql
query GetUser($id: ID!) {
  user(id: $id) {
    id
    name
    email
    posts {
      title
    }
  }
}

>>>variables
{
  "id": "123"
}
<<<

>>>
expect status 200
expect body.data.user.id == "123"
expect body.data.user.name exists
expect body.errors !exists
<<<

Mutations

### Create a new user
# @name createUser

POST {{baseUrl}}/graphql
Content-Type: application/json

>>>graphql
mutation CreateUser($input: CreateUserInput!) {
  createUser(input: $input) {
    id
    name
    email
  }
}

>>>variables
{
  "input": {
    "name": "Jane Doe",
    "email": "jane@example.com"
  }
}
<<<

>>>
expect status 200
expect body.data.createUser.id exists
expect body.errors !exists
<<<

>>>capture
newUserId from body.data.createUser.id
<<<

Variables with Interpolation

hitspec variables work inside the >>>variables block:

>>>variables
{
  "id": "{{login.userId}}",
  "limit": {{pageSize}}
}
<<<

hitspec automatically wraps your GraphQL query and variables into the standard JSON format ({"query": "...", "variables": {...}}) before sending the request. You only need to set Content-Type: application/json.

Asserting GraphQL Responses

GraphQL responses follow a standard structure. Use JSON path assertions to validate both data and errors:

>>>
# Verify the query succeeded
expect status 200
expect body.errors !exists

# Validate response data
expect body.data.users type array
expect body.data.users length > 0
expect body.data.users[0].id exists
expect body.data.users[0].email matches /^.+@.+\..+$/
<<<

To test for expected GraphQL errors:

>>>
expect status 200
expect body.errors type array
expect body.errors[0].message contains "not found"
<<<
