![]() The Rangers fight as best they could but the monster is too fast for them and. With his first attack on the city, he terrorizes the citizens of Briarwood, all the while drawing fake mustaches on people's faces, until the Mystic Force Rangers show up. ![]() Jester is seemingly mentally unstable due to his irrational actions but is extremely powerful. I’ve also updated the Invoke-Pester Wiki page with a more detailed description of how the Script parameter works, because I had a hard time with the way it was worded originally and found that people I spoke with didn’t even realize this feature existed.Jester the Pester is called forth by Imperious to use Dark Magic and attack the city so is given a Dark Pen to use in the city. This is just one way that passing parameters to Pester tests can be used, and I hope this example will help anyone else that’s looking to use Pester. Get-VMHostNetwork -VMHost $server | Set-VMHostNetwork -DnsAddress $esxdns -ErrorAction Stop Write-Warning -Message "Remediating $server" If so, the logic to fix the discrepancy is run. The test then runs against the configuration file supplied and, if it finds a drift in the desired outcome versus the current state, will see if $Remediate has been set to true (switched on). As an example, here is my 1 file: īy making both parameters Mandatory and also using ValidateNotNullorEmpty I can ensure that the tests won’t run without supplying inputs. In order to receive the variables being passed by Pester, I’ve also set up params within the Pester tests themselves. I see this being handy for complex environments that want to use different values for sections of the data center. Config: A string value that contains the location of configuration values to check against.Essentially – should the Test fix the drifted value, or just report it? Remediate: A switch value to trigger remediation for the Pester test as opposed to simply running the test for validation.It contains another hashtable of key/value pairings that will be passed along to the Pester tests. The second key in the hashtable, Parameters, is optional. You can supply any path to where the tests live. While it can be any location on the system, I’ve placed the folder into the root and am thus calling it from there. The first key in the hashtable, Path, is a required entry that tells Pester where to find the tests. To begin, let’s look at an example: Invoke-Pester -Script = '.\Vester\Tests' Parameters = Remediate = $false Config = '.\Vester\Tests\Config.ps1' }} When a hashtable is passed as a value, the option of passing parameters directly into Pester tests become available. To grant more control to the testing process, I have begun using the Script parameter available within Invoke-Pester. This is especially true for more specific testing, such as isolating just one or two tests, to check for configuration values without necessarily enforcing them. I had originally set the boolean value for remediation inside of the configuration file, but realized that it would be far more useful if I let the user pass along that decision when Pester is called. In my recently renamed Vester project, I leverage Pester to comb through a set of configuration values and validate them against a vSphere environment (hence vSphere Pester = Vester). I’m really digging the use of Pester for unit tests and functional tests across my various PowerShell projects.
