• You can test multiple requests using Collection, select Run All option from the collection menu.
• The collection runner will execute all requests and test cases and display the result.

• I noticed we need to write lot of boilerplate code in Postman and other clients to do basic testing using scripting like status code equal 200. So I implemented GUI based tests, where you select couple of dropdowns to do most standard tests very easily without any scripting knowledge.

  • From the tests tab select Set Env Variable option and enter the json property
  • In value input enter the variable name when its matches name in Env, it will turn green, if variable not exists, it will create new.
  • Now execute the request you will see the variable value set in the Env.
  • Set Variable from Text Response: Enter text keyword in the left input
  • Set Variable from Header: Enter header.headerName in the left input, the prefix is header.
  • Set Variable from Cookie: Enter cookie.cookieName in the left input, the prefix is cookie.
