Re: Get the number of the current test when debugging a test script

You want a conditional break point. From "perldebug":

b [line] [condition]
Set a breakpoint before the given line. If a condition is specified, it's evaluated each time the statement is reached: a breakpoint is taken only if the condition is true. Breakpoints may only be set on lines that begin an executable statement. Conditions don't use if:
    b 237 $x > 30
    b 237 ++$count237 < 11
    b 33 /pattern/i

If the line number is ., sets a breakpoint on the current line:
    b . $n > 100

Yes, but I don't "know" which line to put it on. I don't want to have to trawl through the code manually counting my tests to find which one the test fails after. ~~I was disappointed to find that you can't have a conditional watch, actually (e.g. watch for when $var == 3).~~ Update removed misconception thanks to RonW To watch for a variable reaching a certain value, you need `w (3 == var)` or just `w var == 3`	[reply] [d/l] [select]

Based on the description in "perdebug": `w expr` [download] Add a global watch-expression. Whenever a watched global changes the debugger will stop and display the old and new values. I would expect `w (3 == $var)` to do what you are asking for.	[reply] [d/l] [select]

Aha! Thanks RonW, I didn't quite get that. I just need the expr to return true. Spot on.	[reply]
