Binary Subtraction Function

Function Name

$subtract(intA, intB)

Function Description

Implements the subtraction operation between parameter A and parameter B. Parameters A and B support the following types:

Numbers
Local parameters
Binary operations

Application Scenarios

The binary subtraction function can be used in the following scenarios for API automation:

Request URL
Request header
Request body
Checkpoint property
if condition
for loop interrupt condition

Example

Request URL
As shown in the following figure, the value of the test parameter in the request URL is the binary subtraction function. Parameters A and B in the function are 1001 and 1000 respectively.
Request header
As shown in the following figure, the value of parameter subtract in the request header is the binary subtraction function. Parameter A in the function is the binary multiplication function $multiply(100,100), and parameter B is -1.
Request body
As shown in the following figure, the binary subtraction function is used in the request body. Parameter A in the function is the binary division function $divide (1000,100), and parameter B is the binary addition function $add (1000,1000).
Checkpoint property
As shown in the following figure, the target value of the checkpoint property result is the binary subtraction function. Parameter A in the function is the local parameter test, and parameter B is 1. For details about how to set local parameters, see Local Parameters.
if condition
As shown in the following figure, the target value of the if condition is the binary subtraction function. Parameter A in the function is 1001, and parameter B is the environment variable status. For details about how to set environment parameters, see Setting Environment Parameters of an API Script.
for loop interrupt condition
As shown in the following figure, the target value of the for loop interrupt condition is the binary subtraction function. Parameters A and B in the function are 1001 and 1000 respectively.
