Dynamic Variables in Postman
Postman provides a variety of dynamic variables that can be utilized to generate realistic and random data during API testing. These dynamic variables add flexibility and randomness to requests, enhancing the robustness of your test cases. Here are a few key dynamic variables and their use cases:
1. $guid (UUID)
- Description: Generates a uuid-v4 style guide.
- Examples: “611c2e81-2ccb-42d8-9ddc-2d0bfa65c1b4”, “3a721b7f-7dc9-4c45-9777-516942b98e0d”, “22eca807-006b-47df-9511-e92e37f5071a”
2. $timestamp
- Description: Provides the current UNIX timestamp in seconds.
- Examples: 1562757107, 1562757108, 1562757109
3. $randomInt
- Description: Generates a random integer between 0 and 1000.
- Examples: 802, 494, 200
4. $randomAlphaNumeric
- Description: Generates a random alpha-numeric character.
- Examples: 6, “y”, “z”
5. $randomIP
- Description: Generates a random IPv4 address.
- Examples: 241.102.234.100, 216.7.27.38
6. $randomEmail
- Description: Generates a random email address.
- Examples: “Pablo62@gmail.com”, “Ruthe42@hotmail.com”, “Iva.Kovacek61@hotmail.com”
7. $randomUrl
- Description: Generates a random URL.
- Examples: “https://anais.net”, “https://tristin.net”, “http://jakob.name”
8. $randomCurrencyCode
- Description: Generates a random 3-letter currency code (ISO-4217).
- Examples: “CDF”, “ZMK”, “GNF”
By using Dynamic Variables, incorporate these variables in your requests to dynamically generate data. They enhance test scenarios with realistic and diverse inputs. And, increases the adaptability of your tests to various conditions.
