When these errors occur, they are considered “terminating errors.”Īs an example, if you want to stop the execution of your Windows PowerShell script when an error occurs during a call to Stop-Process, you can simply add the -ErrorAction parameter and use the value Stop: If you set $ErrorActionPreference to Stop or if you use Stop as the parameter value for -ErrorAction, Windows PowerShell will stop the script execution at the point an error occurs. Hence, these types of errors are known as “non-terminating” errors. This variable is part of a handful of variables known as “preference variables.” By default, Windows PowerShell uses an error action preference of Continue, which means that errors will be written out to the host, but the script will continue to execute. When you specify the ErrorAction parameter during a call to a command, the specified behavior will override the $ErrorActionPreference variable in Windows PowerShell. However, advanced functions cannot be suspended. If you’re developing a Windows PowerShell workflow, you can also use the Suspend value. The available options are: Stop, Continue, Silentl圜ontinue, Ignore, or Inquire. The -ErrorAction common parameter allows you to specify which action to take if a command fails. # Take administrative action on error state Stop-Process -Name invalidprocess2 -ErrorVariable +ProcessError Stop-Process -Name invalidprocess -ErrorVariable ProcessError

If you want to append an error to the variable, instead of overwriting it, you can put a plus sign ( +) in front of the variable name. It’s important to note that even when you use the -ErrorVariable parameter, the $error variable is still updated.īy default, the -ErrorVariable parameter will overwrite the variable with the name that you specify. When you use the -ErrorVariable parameter in a call to a command, the error is assigned to the variable name that you specify.
Normally, if you run a Windows PowerShell command and an error occurs, the error record will be appended to the “automatic variable” named $error.
One of the benefits of developing cmdlet-style commands instead of basic functions, is that they offer a few “common parameters.” Two of these common parameters are related to error handling: -ErrorAction and -ErrorVariable.įor more information about common parameters in advanced functions and compiled cmdlets, run this command at the Windows PowerShell prompt: This concept allows you to develop commands that have the same feel as compiled cmdlets, while writing them in Windows PowerShell script syntax. When Windows PowerShell 2.0 came out, a new concept was introduced, called Advanced Functions. On the other hand, if you’re new to scripting, or you are a curious, knowledge-driven individual, you might want to consider what we’re talking about today.

If you’re coming to Windows PowerShell from a software development background, you’ll most likely pick up on Try-Catch-Finally pretty easily. But have you ever wondered if that was the only way to handle errors? It turns out that although it’s a great way to handle errors, there are still other options!

Microsoft Scripting Guy, Ed Wilson, just wrote a post about how to use the Try-Catch-Finally blocks in Windows PowerShell. Today we have guest blogger and Windows PowerShell MVP, Trevor Sullivan… also find Trevor on Twitter ( ) and his blog ( ) Microsoft Scripting Guy, Ed Wilson, is here. Pester itself will even display pending tests in its output.Summary : Trevor Sullivan talks about handling errors in Windows PowerShell. This allows you to stub out needed tests without them interfering with your code. This will cause Pester to skip over the test.
Pester has a switch you can pass to It called –Pending. Once I’ve created the list, I then go into my test script, and create It statements for each test. When I create a Pester test, for example for a function, I outline all the things I need to test. The new 2016 version has an interesting new capability that while it may seem small, works extremely well when developing Pester tests. I’ve been working a lot with Peter lately, and as I’ve blogged about before I use Sapien’s PowerShell Studio tool.
