MAF - API Module

This module is created to allow other projects to easily perform API requests, utilizing a set of steps.

Dependencies

This module is dependent on the following npm modules:

• fetch-blob
• node-fetch
• form-data
• fetch-to-curl

Set up

1. Install by running npm i @ln-maf/api

2. Add a new step file in the features folder with the following code:

require('@ln-maf/api')

Global MAF API Variables

• url: The url to use for the api request. Should be a string including the protocol. ex: 'https://google.com'
• api: The api to use for the api request. Should be a string. ex: 'driver/users/1'
• body: The body to use for the api request. Should be a string.
• jsonBody: The json body to use for the api request. It must be in a valid JSON object format
• urlEncodedBody: The url encoded body to use for the api request. It will be appended to the url
• headers: The headers to use for the api request. Should be a JSON object. Note that the default headers are remove if this is used. The default headers are documented here in the node-fetch documentation.
• method: The method to use for the api request. Should be a string. ex: 'GET', 'POST', 'PUT', 'DELETE'

Step Definitions

Given url {string}

Deprecated: Set the item 'url' instead

Assigns a string to the url item

Given api {string}

Deprecated: Set the item 'api' instead

Assigns a string to the api item

Given body {string}

Deprecated: Set the item 'body' instead

Defines the body for a given request

Given headers {string}

Deprecated: Set the item 'headers' instead

Takes a string of headers. These should represent a json object. Note that the default headers are removed if this is used. The default headers are documented here in the node-fetch documentation.

When api request from{jsonObject}is performed

Performs a request based on the json file and given values. An example json file would be:

{
    "api": "driver/users/1",
    "method": "POST",
    "headers": {
      "Accept": "application/json",
      "X-Api-Service-Version": "2.0",
      "Content-Type": "application/json",
      "X-AliasRequired": false
    },
    "body": {
      "clientNumber" : "111",
      "email": "1@1.com"
      "mobilePhone":"1"
    }
  }

After the request is performed, the results will be stored in ${lastRun} consistent with the global cucumber testing standard, and in ${response}. This can be accessed in other tests following this standard with the template literal ${lastRun} or ${response}.

When api request is performed

Performs a request based on the global variables set. The global variables are listed above.

When perform api request: {docString}

Performs using a doc string instead of a file. Please see When api request {string} is performed

Example:

When perform api request:
"""
{
  "url" : "http://google.com",
  "method": "GET"
}
"""

How to perform a multi-part request

The request supports and additional body type of: formBody. This supports arrays(untested) and will append it to element + [].
As of now the only portion of this that is tested and is not included in this CI is the file. Hopefully this will be tested in more detail soon.

An example would be:

{
    "api": "/driver/upload?ft=1&fn=${outputFilename}",
    "headers": {
        "X-Api-Key": "${apiKey}",
        "X-File-Format": "DECRYPTED",
        "X-File-Format-Version": "4.0",
        "accept": "application/json",
        "accept-encoding": "gzip",
        "accept-language": "en-US,en;q=0.9",
        "authorization": "Bearer ${a_t}",
        "sec-fetch-mode": "cors",
        "sec-fetch-site": "same-origin",
        "x-api-service-version": "1.0"
    },
    "formBody": {
      "file": {
        "type": "file",
        "fileName": "${outputFilename}"
      },
      "stringParam": "string",
      "numParam": 3,
      "blobParam": {
        "type": "base64blob",
        "base64blob": "SEVMTE8gV09STEQ="
      },
      "stringArray": ["hello", "world"],
      "fileArray": [
        {
          "type": "file",
          "fileName": "${outputFilename}"
        },
        {
          "type": "file",
          "fileName": "${outputFilename2}"
        }
      ]
    },
    "method": "POST"
}

When method post

Deprecated: Set the item 'method' to 'POST' and call the method 'api request is performed' instead

Performs a post using the defined values listed above and stores the result in this.results.lastRun which can be accessed with ${lastRun}

When method get

Deprecated: Set the item 'method' to 'GET' and call the method 'api request is performed' instead

Performs a post using the defined values listed above and stores the result in this.results.lastRun which can be accessed with ${lastRun}

Then the status is ok

Makes sure that response.status is between 200 and 299.

Then status ok

Deprecated: Use the status is ok, the status is {int} or the status is not ok instead

Makes sure that response is between 200 and 299.

Then the status is not ok

Makes sure that response.status is not between 200 and 299.

Then status not ok

Deprecated: Use the status is ok, the status is {int} or the status is not ok instead

Makes sure that response.status is not between 200 and 299.

Then the status is {int}

Makes sure that response.status is equal to the integer specified.

Then status {int}

Deprecated: Use the status is ok, the status is {int} or the status is not ok instead

Makes sure that response.status is equal to the integer specified.
