Creating a Docker Image with the AWS module installedĪs I was also testing some code that used the AWS module, instead of installing the module each time the test ran which would add significantly more time to the test, creating a new docker image with the module already installed with a DockerFile allowed me to create a container with the necessary module. Once the container is created, Invoke-Pester is executed in the directory containing the tests and the results are outputted to a file in the /tests directory which will write to the local directory on the laptop once the container is run and has exited (type exit in the container) and has been removed (the rm command). The directory on my laptop is ~/Documents/PowerShell and the directory in the container is /tests.The -w option is used to set the working directory in the container to /tests. I run docker to create a container with a directory mapped to a volume in the container from my host laptop. Invoke-Pester -OutputFile results.xml -OutputFormat NUnitXml
I had downloaded the microsoft/powershell Docker image from Docker Hub to my local machine from the docker repository. I did this using PowerShell Core 6 running on a Ubuntu laptop. So you may not be able to use this method to test your scripts if they rely on cmdlets only available in the Desktop Edition.įor a guide to installing Docker, see the docker docs on installing. Note: The docker image runs the PowerShell Core Edition which doesn’t have all the modules as the Desktop Edition (see Microsoft overview of PowerShell editions). You can unload all modules and check the environment variables but I was following a Docker course on and thought it would be pretty cool to use the PowerShell docker image from Microsoft to spin up a container, run the tests on a “clean” system and then output the results. When running Pester tests, it’s nice to know that you are running against the correct version of the module you are testing and there are no environment variables that could influence the test in an unexpected way.
In addition, the importance of having good requirements was stressed. The types of testing, unit, integration, and acceptance were discussed.

Some officials worried that if such a move were to be challenged in court, it could undermine the full faith and credit of the U.S.īiden said recently he has been “considering” the 14th Amendment but concluded that it would not solve the current stalemate, given that “it would have to be litigated.” But the White House Office of Legal Counsel continues to study the matter, according to a source familiar with the talks, for possible future unilateral use.Using Docker container for Pester testing In part 1 of this series, Introduction to Testing Your PowerShell Code with Pester, I covered the basics of using the Pester module to test your PowerShell code. Pester version : 5.1.1 C:\Program Files\WindowsPowerShell\Modules\Pester\5.1.1\Pester. Then-President Barack Obama's administration looked into it, but his Justice Department never made its opinion on the matter public. The code Invoke-Pester -ErrorAction Stop placed in a Try clause does not trigger the Catch clause. But the Biden administration and its predecessors have been reluctant to invoke the 14th Amendment. There's much more to writing Pester tests, and I encourage you to learn the details via The Pester Book. Some experts believe the debt ceiling statute is unconstitutional and cannot prohibit the U.S. McCarthy flatly ruled out the idea of tax increases on top earners at a news conference Wednesday. In the letter, which was first reported by The Washington Post, the Democrats say the GOP's unwillingness to raise taxes on the wealthy and large corporations makes it "seemingly impossible to enact a bipartisan budget deal at this time."
