Example

Simple example

url="https://httpbin.org"

GET /ip
Response

POST form

url="https://httpbin.org"

POST /post Post form
header["Content-Type"] = "application/x-www-form-urlencoded"
form.key0 = "value0"
form.key1 = "value1"
Response
must(status==200)

POST form file

url="https://httpbin.org"

POST /post Post file
header["Content-Type"] = "multipart/form-data; boundary=" + boundary
form.key0 = "value0"
form.key1 = "@/etc/hosts"
Response
must(status==200)

POST json data

url="https://httpbin.org"

POST /post Post json data
header["Accept"] = "application/json"
header["Content-Type"] = "application/json"
json.key0 = "value0"
json.key1 = "value1"
Response
must(status==200)

Use variable in path

url="https://httpbin.org"
some="thing"

GET /etag/:some Just a GET request
Response
must(status==200)

Parse JSON

url="https://httpbin.org"
some="thing"

POST /post Post json data
header["Accept"] = "application/json"
header["Content-Type"] = "application/json"
json.key0 = "value0"
json.key1 = some
Response
must(status==200)
j = JSON.parse(body)
must(j.origin.length > 3)

Create variable and use it later

url="https://httpbin.org"

POST /post Post json data
header["Accept"] = "application/json"
header["Content-Type"] = "application/json"
json.key0 = "value0"
json.key1 = "value1"
list=[]
list.push("value3")
list.push("value4")
json.key2 = list
Response
must(status==200)
j = JSON.parse(body)
myip = j.origin // created a new variable

GET /etag/:myip Just a GET request
query.key0 = myip // use a varible you created earlier
Response
must(status==200)

Use builtin function

url="https://httpbin.org"

GET /get
query.key0 = md5("value0")
Response
must(status==200)

Print

url="https://httpbin.org"

GET /ip
Response
must(status==200)
console.log(body)

Run case

# Default case file is ./test.frank
$ frank

# Specifies case file path
$ frank -c /path/to/case/file

# Set 500ms request interval
