Check for difference between two values [message #1698382]

Dear fellow Jubula-users Razz

I have to test two programs in parallel, in first i set number 1.000 (float) and check the output.

However output program shows it with some deviation 1.032 (number after comma might vary )

In fact it is right value, but how to set it in Jubula, so the test doesnt fail?

how to generally deal in Jubula with deviation recognition?

Output program can have deviation show up tp +/- 0.05

Thanks in Advance

Hi,

have you tried to use wildcards to deal with the deviation?
Regards

The mathematical functions come in handy here:
1. Store Value: variable name INPUT, value <input value>
2. Store Value: variable name OUTPUT, value <output value>
3. Store Value: Variable name DEV, value "?mult(0.05,$INPUT)"
4. Store Value: variable name DIFF, value "?sub($OUTPUT,$INPUT)"
5. Check Numeric Values: value1 "$DIFF", operator "less or equal than", value2 "$DEV"
5. Check Numeric Values: value1 "$DIFF", operator "greater or equal than", value2 "?mult($DEV,-1.0)"
