💡 Hint

Common Mistakes

Forgetting to put quotes around the string value.

Using variable names instead of string literals.

The pm.globals.set function requires the value to be a string, so it must be enclosed in quotes.

💡 Hint

Common Mistakes

Using incorrect field names or wrong case.

Using quotes around the field name inside the JSON accessor.

The response JSON field is named 'id', so we access it with pm.response.json().id.

💡 Hint

Common Mistakes

Passing variable name without quotes causes a ReferenceError.

Confusing variable name with variable value.

The variable name must be a string, so it needs quotes around it.

4fill in blank

hard

C'items'

Dcount

💡 Hint

Common Mistakes

Using quotes around JSON field names in dot notation.

Not quoting the variable name string.

The variable name 'count' must be a string, so it needs quotes. The array is named 'items' in the JSON, accessed without quotes.

5fill in blank

hard

Fill all three blanks to set an environment variable 'status' to 'success' only if the response JSON field 'code' equals 200.

Postman

  pm.environment.set([3], 'success');
}

Drag options to blanks, or click blank then click option'

Acode

B200

C'status'

D'code'

💡 Hint

Common Mistakes

Using quotes around JSON field name in dot notation.

Using quotes around the number 200.

Not quoting the variable name string.

We check if the JSON field 'code' equals the number 200, then set the environment variable 'status' (string) to 'success'.
