Note You can always tell if you are in the debugger by testing for $PSDebugContext. I can also look at the $DebugContext automatic variable that is created when entering the debugger to see if there is anything useful there. Neither of them offers me anything because I am in the debugger. I could choose to continue stepping through the handler but in this case, I am simply exploring some of the variables such as $PSBoundParameters and $args. Now we can run the script and wait for the error to occur.Īfter breaking on Set-Strictmode, we can see where the handler is by using ‘l’. Get-WmiObject breakpoint will now target the Set-StrictMode cmdlet, and it will put me in the debugger whenever this command occurs: We can break into the debugger whenever a command is used! I am going to modify my script a bit to remove the error handling and error variable for the sake of this demonstration. We need to move to the next line of the script to see what the error is. I cannot actually view the error yet because it hasn’t been written to the variable. Get-WmiObject expected, when an error occurs with my WMI query, the error is written to the $WMIErrors variable, which throws me into the debugger, based on the breakpoint that I set. Set-PSBreakpoint -Variable WMIErrors -Mode Write We can use the –ErrorVariable parameter and then set a breakpoint against that variable to send us to the debugger to further investigate what is going on. Let’s say we want to see whenever an error occurs with a command. We can set a breakpoint on a variable based on three actions: So I have had a little fun with the ISE, but now I am going to turn my attention to the console and show how we can set breakpoints on scripts or commands by using Set-PSBreakPoint (these also can be used in the ISE).

If you want these variables to be available, you need to assign the values to a different variable. I can also use Get-PSCallStack to see where we are in the current call stack.Īnother thing worth noting is that there are a few variables that hold a value in the debugger that is different from the value they would have in the script or function. In the console, we would be making liberal use of ‘list’ to see where we actually are. The nice thing about the ISE is that the tracking for each line is shown as a highlighted row.

Knowing this, we can begin debugging the code and tracking the progress of each line, if needed, or simply move to the next breakpoint. We can also find all the available debugging commands by typing ? (questions mark) at the debug prompt. If we have other breakpoints set, we can type c (continue), and the code will execute to the next breakpoint. These are the same commands that are available in the console. Now that we have hit the debugger, we can start working with some of the available debugging commands to further explore the code and step through various parts. Eventually, the first breakpoint will trip and then the console will enter the debugger. I am going to run this in the ISE to set up a couple of breakpoints and see what everything is doing. Let’s image that I have a script that I want to test to make sure it behaves properly. The following table lists the keyboard shortcut. When you hit that breakpoint, it shows up in the ISE, making it easier to tell where you are. I'll look at the console and the ISE to help troubleshoot different parts of the code.ĭebugging in the ISE is nicer because you can use keyboard shortcuts to set breakpoints on various lines of code.
