2. Make a call1. Login & Create Test Case

3. Test the call1. Verify Status Code

2. Verify Speed

3. Verify Response

Postman Examples (continued)

1. Set up variables (to use/store in the next call)

2. Check for a security flaw1. Same verifications

3. Runner GUI

4. Download a collection

5. Download the environment (staging/dev)

Newman Example

1. Let’s test that same collection from the commandline

INSERT PHOTO ON TOP

Jenkins Example

1. Simple shell to execute newman

2. Use script to upload test results to qTest, just to show the full cycle if we wanted to not just include API testing in our CI, but to have a documented, easy to read record of what was tested

I just showed you one example of a tool set that you could use, but there are countless others!

Other Options!
