Local variables in Postman - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are local variables in Postman?

Local variables in Postman are variables that exist only during the execution of a single request or script. They are temporary and get deleted after the request finishes.

How do local variables differ from environment variables in Postman?

Local variables last only during one request execution, while environment variables persist across multiple requests and collections until changed or deleted.

beginner

How do you set a local variable in a Postman test script?

Use `pm.variables.set('variableName', 'value')` inside the script to create or update a local variable.

beginner

How do you get the value of a local variable in Postman?

Use `pm.variables.get('variableName')` to retrieve the value of a local variable during the request execution.

beginner

Why use local variables instead of environment variables in Postman?

Local variables are useful for temporary data that only matters during one request, avoiding clutter or accidental reuse in other requests.

Which Postman method sets a local variable?

A pm.environment.set()

B pm.collectionVariables.set()

C pm.globals.set()

D pm.variables.set()

pm.variables.set() sets a local variable that lasts only during the current request execution.

How long do local variables last in Postman?

A Until manually deleted

B Only during the current request execution

C Until the environment is cleared

D Forever across all requests

Which method retrieves a local variable's value in Postman?

A pm.globals.get()

B pm.environment.get()

C pm.variables.get()

D pm.collectionVariables.get()

Why might you prefer local variables over environment variables?

A They avoid clutter by being temporary

B They are easier to share

C They are stored permanently

D They persist across requests
