Conditional breakpoints
Conditional breakpoints limit data collection from a code snippet to cases when the defined expression evaluates as true.
Rookout provides two types of conditions:
- Simple - compare the value of one or two variables.
- Advanced - define a complex condition using logical parameters (use "&&" for AND statement, "||" for OR statement, "(" and ")" for encapsulation).
Add and Edit Conditional breakpoints:
- Set a breakpoint.
- Click on the
icon in the breakpoint pane. - Choose condition type - Simple or Advanced.
- Set your condition.
Advanced conditions - supported operators and functions:
| Operator | Example | Description |
|---|---|---|
== | a==1, b=='bbb', x==y | If the values of two operands are equal, then the condition becomes true. |
!= | a!=1, b!='bbb', x!=y | If values of two operands are not equal, then condition becomes true. |
> | a>1, x>y | If the value of left operand is greater than the value of right operand, then condition becomes true. |
>= | a>=1, x>=y | If the value of left operand is greater than or equal to the value of right operand, then condition becomes true. |
< | a<1, x<y | If the value of left operand is less than the value of right operand, then condition becomes true. |
<= | a<=1, x<=y | If the value of left operand is less than or equal to the value of right operand, then condition becomes true. |
&& | a<=1 && b!='bbb' | If both the operands are true then condition becomes true. |
|| | a<=1||b=='bbb' | If any of the two operands are non-zero then condition becomes true. |
() | (a<=1||b=='bbb') && (x<y) | Parentheses could be used for changing the precedence when evaluating the conditio |
[] | arr[4]!=4, dict['a']!=4 | Set conditions regarding to a specific sequence’s element - list, dict etc. |
size | arr.size() >= 32 | Use size instead of len or length on any platform |
