har-to-expectations

CLI tool to convert HAR file to expectations .json file which is ready for the Mock-Server

Exported .json file is then ready to be either further manually modified or sent to the Mock-Server as is.

You could use this tool to handle this easily from CLI.

Installation

npm install -g @bednarik_radek/har-to-expectations

Usage

To display CLI help run:

npx har -h

You should see something like this:

Usage: har [options] [command]

Options:
  -h, --help                            display help for command

Commands:
  convert <harPath> <jsonPath> <regex>  converts .har file to .json file with expectations.
  help [command]                        display help for command

Example

• we have exported a HAR file from the browser to the ./har folder
• we want to convert it to the ./expectations folder

npx har convert ./har/requests.har ./expectations/expectations.json "https://www.example.com"

This command will do the following:

• read the ./har/requests.har file and parse it to the JSON object with Har typings

• filter out all requests which are not matching the https://www.example.com regex

• convert the remaining requests to the JSON object as valid expectations

• save the result to the ./expectations/expectations.json file

Important notes

This utility is not doing full .har-to-.json conversion. It is only converting the requests and responses from the .har. Also, it is only adding certain parts of to expectations from requests/responses, which are needed to use them as mocks.

What is converted

• request

  • method
  • pathname
  • body, if it is present
  • query parameters, if they are present

• response

  • status code
  • response body, if it is present
