Testpoint Constraints
A Constraint is typically composed using local and member variables in expressions, separated by operators to define one or more specific criteria that must be met. A constraint must evaluate as true to be considered as Passed. If a constraint evaluates as false, it is considered as Failed.
Any variables referenced within the constraint must be in scope at the position where the Testpoint or Breakpoint is evaluated.
General/Arithmetic Operators
Operator 
Description 
See also 

+ 
Add Example: a + b > 0 

 
Subtract Example: a  b > 0 

/ 
Divide Example: a / b == 2 

* 
Multiply Example: a * b == c 

% 
Modulus Example: a % 2 == 1 

( ) 
Parentheses  Used to define precedence in complex expressions. Example: ((a / b) * c) <= 100 

[ ] 
Square Brackets  Used for accessing Arrays. Example: Names[0].Surname == "Smith" 

. 
Dot operator  Used to access member variables of a Class. Example: Station.Name == "Flinders" 

> 
Alternative notation for the Dot operator. Example: Station>Name == "Flinders" 
Comparison Operators
Operator 
Description

= 
Equal To Example: a = b 

== 
Equal To Example: a == b 

!= 
Not Equal To Example: a != b 

<> 
Not Equal To Example: a <> b 

> 
Greater Than Example: a > b 

>= 
Greater Than or Equal To Example: a >= b 

< 
Less Than Example: a < b 

<= 
Less Than or Equal To Example: a <= b 
Logical Operators

AND 
Logical AND Example: (a >= 1) AND (a <= 10) 

OR 
Logical OR Example: (a == 1) OR (b == 1) 
Bitwise Operators
Operator 
Description 
See also 

& 
Bitwise AND Example: (1 & 1) = 1 (1 & 0) = 0 

 
Bitwise OR Example: (1  1) = 1 (1  0) = 1 

^ 
Bitwise XOR (exclusive OR) Example: (1 ^ 1) = 0 (1 ^ 0) = 1 
Additional Examples
Example 
Description 

(( m_nValue & 0xFFFF0000) == 0) 
Use a Bitwise AND operator (&) with a hexadecimal value as the right operand to test that no bits are set in high order bytes of the variable. 
(( m_nValue & 0x0000FFFF) == 0) 
Use a Bitwise AND operator (&) with a hexadecimal value as the right operand to test that no bits are set in low order bytes of the variable. 
m_value[0][1] = 2 
Accessing a multidimensional array 
a AND (b OR c) 
Combining AND and OR operators, using parentheses to ensure precedence. In this example, variable 'a' must be true, and either 'b' or 'c' must be true.

 String comparisons are casesensitive
