Newman supports everything that Postman does, so if you are ever unsure of how to do something in Newman that you can do in Postman, check out the Newman documentation – you will find a way to do it. There are several other options that Newman offers. You can also specify the -ignore-redirects option to prevent the redirect links from being automatically followed. This option will disable strict SSL, which is sometimes required if you are getting SSL certification errors when running your request. Another option you may need to use occasionally is the -k option.

You can also use the folder modifier as a way to skip running the entire collection if some of the inputs are incorrect. By default, it will stop the run as soon as a failure is detected, but if you want it to complete the current test script before stopping, you can specify it as -bail failure. You can also use options such as -bail, which lets Newman know that you want it to stop running as soon as any failure occurs. These three flags are all need you to specify a number that represents the amount of time in milliseconds. You can get even more targeted than that if you want by specifying the -timeout-script option, which sets the maximum amount of time any of the scripts (such as test or pre-request scripts) can run before you consider them to have timed out. A more targeted option for this is -timeout-request, which specifies the amount of time to wait for a request to complete before considering it to have timed out. You will want to be careful with this value since it can be hard to figure out how long it will make sense for this to be if you have a lot of requests in the collection. You can specify the -timeout flag to set a timeout value for how long you want to wait for the entire collection to run. You can also specify timeout values, which will dictate how long Newman waits for certain actions to happen before it considers them to have timed out. For example, if you had a POST request that created some data and then you were running a GET request to check whether that data was there, you might want to put in a slight delay so that the server has time to fully process the POST request. You might want to use this if you have requests that depend on each other. This option allows you to specify an amount of time (in milliseconds) that Newman should wait after a request finishes before it starts the next request. Created: October 30, 2018Version Published. It allows you to effortlessly run and test a Postman collection. Another option you may want to use is the -delay-request option. Newman is a collection runner for Postman.
