Hi Esther how are you doing? trust well. I have been following your work and i am kinda stuck on the newman part. my system Keeps reading : "newman : The term 'newman' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1 newman run test.postman_collection.json -e baseurl.postman_environmen ... ~~ CategoryInfo : ObjectNotFound: (newman:String) [], CommandNotFoundException FullyQualifiedErrorId : CommandNotFoundException". After I have installed newman, please what could be the cause? Once again thanks for your work
