  • Introduction (As commented by the author in PowerShell Pro…) PowerShell is a new command shell from Microsoft and yes it is a command prompt and scripting environment, it can even be both at the same time. For a systems administrator, the benefits in learning PowerShell are mainly pertaining to Active Directory domains are becoming larger and more complex. For those administrators that are still chained to GUI tools and the Microsoft Management Console, PowerShell will set you free!!! Additional Features to MS-DOS Command: • Variables, Constants, Arrays, and Hash Tables. • Using Conditional Logic. • Processing data with Loops. • Modular Scripting Using Functions. • Scripting using WMI Objects (Computers, Printers, Etc…). • Scripting using ADSI Objects (Active Directory Management Concepts: Object Based Not Command Based – Output can be piped into another input Commands are customizable – Create own commands, based on aliases Command Based and Scripting Environment – MS DOS – command and VB Script – runs Windows Server Host for executing scripts and not MS DOS runs the command. Same applies for Windows Batch File 2

  • CAFFEINATED ODOR WEBSITE Features : Guessing: In powershell, the verb-noun pattern is strictly enforced and the names are always consistent so that I can write Get-Command *service and be assured that I will get all the cmdLets related to services and then figure out what they do through the verb part of their name. Built-In Help -If you're not sure what a cmdLet does, then use the Get-Help cmdLet to see the documentation Trusting Operations -Are you afraid to execute a script because you're not sure what it will do? Try the -whatif parameter that is ubiquitous to all commands. For example, del C:f*.txt -whatif will just tell you which files would have been deleted rather th an actually deleting them. Get-Member- add| Get-member to the end of the command and I can see what additional methods I have to work with or what properties I can perform filtering and assorting on 4 View slide

  • Powershell for Testers: A dedicated website of use of PowerShell for Testing: http://testfirst.spaces.live.com/blog/ Project CodePlex by the blogger of previous site; Adam Geras : http://www.codeplex.com/psexpect Project Description A PowerShell library for automating tests. You can use this library to test your scripts, but it is really designed to test things external to PowerShell: your Active Directory configuration, your SharePoint installation, etc. This project was initially released for PowerShell v1.0 and has “I built this so that it would be easier to since been revised so that it works for PowerShell v2.0 (CTP employ PowerShell as a means of and above) as well. I've not run the full suite of tests on all automating tests.” OS/version combinations though, so please log an issue if you find something wonky. I built this so that it would be easier to employ PowerShell as a means of automating tests. I believe the language has features that fundamentally make it a wise choice for automating tests, in particular, when the targets of the tests happens to publish cmdlets. So while you can use it to test your scripts, it really is intended to provide you with the means of writing tests to support the work that you are already doing, whether that is writing scripts, configuring commercial-off-the-shelf products, or developing an application. Note: The decision not to use cmdlets at all in this solution was to avoid the need to install anything on the machines running the target of the tests. This is also why relying on an existing .NET test framework (such as NUnit) wasn't considered the optimal solution. Regards, Scripts of .net A. modules works with powershell 8
  • 10 quick reasons to come up for testing with PowerShell by James Brundage – MSDN PowerShell Team – Microsoft Functional Tester (MSFT) (Source: PowerShell Blog) 1. Being able to run command line programs easier within PowerShell 2. Dynamically generating code or test data for a test case (fuzzing or data-driven testing get a lot easier with this) 3. Being able to access COM easier within PowerShell 4. Being able to embed PowerShell in C# (so you can avoid writing a framework and just embed PowerShell in your infrastructure) 5. Being able to use weakly typed variables within PowerShell 6. Being able to test APIs on the command line, so you test manually and then automate 7. Getting a history of commands, to take what you've explored and turn it into a test case 8. Being able to strongly cast or coerce types when needed 9. Support for verbose, warning, and debug streams to provide additional test information 10. Being able to use PowerShell's systems administration features to help setup or cleanup a test environment is a software verification and validation method in which a programmer tests if Use of PowerShell in Unit Testing individual units of source code are fit for use – In Wiki’s terms 9
