Syntax

Test instructions with arithmetic operations have the following structure:

num

countErrors

num

argument1

operator1

argument2

[ operator2

argument3 ]

num

Keyword, marks the test instruction as a computing operation or a comparison operation

argument1

The name of a variable

If the variable does not exist:

The variable is created automatically when a value is assigned
A comparison operation ends with an error

operator1

Either an assignment operator (=),

or an operator for comparing two numerical values or expressions (<, <=, ==, !=, <>, >=, >),

or an operator for comparing a numerical value with an interval (in, !in)

argument2

The name of an already existing variable,

or a number,

or an interval

Optional:

operator2

argument3

An operator for basic arithmetic operations (+, -, *, /)

and the name of an existing variable or a number

Examples
*num countErrors = 0*	*Assignment: Value 0 is assigned to the variable countErrors*.
*num countErrors = countErrors + 1*	*Assignment: The value of the variable countErrors* is increased by 1
**num itemVAT = itemNet 19%***	*Assignment*: VAT is calculated from the net amount
*num countErrors > 0*	*Comparison: Checking whether the value of the variable countErrors* is greater than 0
*num countErrors in [ 1 : 5 ]*	*Comparison: Checking whether the value of the variable countErrors* falls within the specified interval, i.e. is greater than or equal to 1 and smaller than or equal to 5

Examples

num countErrors = 0

Assignment: Value 0 is assigned to the variable countErrors.

num countErrors = countErrors + 1

Assignment: The value of the variable countErrors is increased by 1

num itemVAT = itemNet * 19%

Assignment: VAT is calculated from the net amount

num countErrors > 0

Comparison: Checking whether the value of the variable countErrors is greater than 0

num countErrors in [ 1 : 5 ]

Comparison: Checking whether the value of the variable countErrors falls within the specified interval, i.e. is greater than or equal to 1 and smaller than or equal to 5

Additional notes

Case sensitivity is irrelevant for keywords and variable names
Until further notice, numerical values must be specified in a technical format, just like e.g. double values in Java:
- no thousands separators
- no commas; dot is used as the decimal separator
- as in the following example: 5123.25
If a numerical value is followed by the percent symbol, the value is automatically divided by 100 internally:
- i.e. 5% is turned into 0.05
In order for a condition value to be considered valid (i.e. executable), all arithmetic or comparison operations assigned to this condition value must have been successfully executed, see also the example in the previous chapter
