# Testing Guidelines
|
|
|
|
Testing is a critical and required part of the PowerShell project.
|
|
|
|
The Microsoft PowerShell team created nearly 100,000 tests over the last 12 years which we run as part of the release process for Windows PowerShell.
|
|
Having all of those tests available for the initial release of PowerShell was not feasible, and we have targeted those tests which
|
|
we believe will provide us the ability to catch regressions in the areas which have had the largest changes for PowerShell.
|
|
It is our intent to continue to release more and more of our tests until we have the coverage we need.
|
|
|
|
For creating new tests, please review the
|
|
[documents](https://github.com/PowerShell/PowerShell/tree/master/docs/testing-guidelines) on how to
|
|
create tests for PowerShell.
|
|
|
|
## CI System
|
|
|
|
We use [AppVeyor](http://www.appveyor.com/) as a continuous integration (CI) system for Windows
|
|
and [Travis CI](http://www.travis-ci.com) for non-Windows platforms.
|
|
|
|
### AppVeyor
|
|
|
|
In the `README.md` at the top of the repo, you can see AppVeyor badge.
|
|
It indicates the last build status of `master` branch.
|
|
Hopefully, it's green:
|
|
|
|

|
|
|
|
This badge is **clickable**; you can open corresponding build page with logs, artifacts, and tests results.
|
|
From there you can easily navigate to the build history.
|
|
|
|
### Travis CI
|
|
|
|
Travis CI works similarly to AppVeyor.
|
|
For Travis CI there will be multiple badges.
|
|
The badges indicate the last build status of `master` branch for different platforms.
|
|
Hopefully, it's green:
|
|
|
|
![Travis-CI-Badge-Green.png](Images/Travis-CI-Badge-Green.png)
|
|
|
|
This badge is **clickable**; you can open corresponding build page with logs, artifacts, and tests results.
|
|
From there you can easily navigate to the build history.
|
|
|
|
### Getting CI Results
|
|
|
|
CI System builds (AppVeyor and Travis CI) and runs tests on every pull request and provides quick feedback about it.
|
|
|
|
![AppVeyor-Github](Images/AppVeyor-Github.png)
|
|
|
|
These green check boxes and red crosses are **clickable** as well.
|
|
They will bring you to the corresponding page with details.
|
|
|
|
## Test Frameworks
|
|
### Pester
|
|
Our script-based test framework is [Pester](https://github.com/Pester/Pester).
|
|
This is the framework which we are using internally at Microsoft for new script-based tests,
|
|
and a large number of the tests which are part of the PowerShell project have been migrated from that test base.
|
|
Pester tests can be used to test most of PowerShell behavior (even some API operations can easily be tested in Pester).
|
|
|
|
Substantial changes were required, to get Pester executing on non-Windows systems.
|
|
These changes are not yet in the official Pester code base.
|
|
Some features of Pester may not be available or may have incorrect behavior.
|
|
Please make sure to create issues in [PowerShell/PowerShell](https://github.com/PowerShell/PowerShell/issues) (not Pester) for anything that you find.
|
|
|
|
### xUnit
|
|
For those tests which are not easily run via Pester, we have decided to use [xUnit](https://xunit.github.io/) as the test framework.
|
|
Currently, we have a minuscule number of tests which are run by using xUnit.
|
|
|
|
## Running tests outside of CI
|
|
When working on new features or fixes, it is natural to want to run those tests locally before making a PR.
|
|
Two helper functions are part of the build.psm1 module to help with that:
|
|
* `Start-PSPester` will execute all Pester tests which are run by the CI system
|
|
* `Start-PSxUnit` will execute the available xUnit tests run by the CI system
|
|
Our CI system runs these as well; there should be no difference between running these on your dev system, versus in CI.
|
|
|
|
When running tests in this way, be sure that you have started PowerShell with `-noprofile` as some tests will fail if the
|
|
environment is not the default or has any customization.
|
|
|
|
For example, to run all the Pester tests for CI (assuming you are at the root of the PowerShell repo):
|
|
```
|
|
Import-Module ./build.psm1
|
|
Start-PSPester
|
|
```
|
|
If you wish to run specific tests, that is possible as well:
|
|
```
|
|
Start-PSPester -Directory test/powershell/engine/Api
|
|
```
|
|
Or a specific Pester test file:
|
|
```
|
|
Start-PSPester -Directory test/powershell/engine/Api -Test XmlAdapter.Tests.Api
|
|
```
|
|
|
|
### What happens after your PR?
|
|
When your PR has successfully passed the CI test gates, your changes will be used to create PowerShell binaries which can be run
|
|
in Microsoft's internal test frameworks.
|
|
The tests that you created for your change and the library of historical tests will be run to determine if any regressions are present.
|
|
If these tests find regressions, you'll be notified that your PR is not ready, and provided with enough information to investigate why the failure happened.
|
|
|
|
|
|
|
|
## Test Layout
|
|
We have taken a functional approach to the layout of our Pester tests.
|
|
You should place new tests in their appropriate location.
|
|
If you are making a fix to a cmdlet in a module, the test belongs in the module directory.
|
|
If you are unsure, you can make it part of your PR, or create an issue.
|
|
The current layout of tests is:

|
|
* test/powershell/engine/Api
|
|
* test/powershell/engine/Basic
