+These packages can be used to test the installation or upgrading of packages that have require an existing package to downgrade.
+
+Each version is available as `upgradedowngradesdependency` and `downgradesdependency`. This is to allow testing of scenarios where `choco upgrade all` would process the dependency before and after the parent package.
+
+- Version 1.0.0 Contains a range that can be used in an upgrade scenario and has a dependency on `isdependency 1.0.0 or greater`
+- Version 2.0.0 Contains an exact dependency on `isdependency` with a version of `1.0.0`

Subject: [PATCH 06/14] (#3461,#3487) Add an all packages source for tests

We have added some tests for the install all command. This adds a new
package source to the testing environment so that we can run the tests
locally and in Test Kitchen.

Subject: [PATCH 08/14] (maint) Remove unnecessary variable usage

In the NugetService we were using a nullResult variable to allow us to
add messages to the result. We do not need this variable if we're only
adding a single message. This commit removes the unnecessary variables.

Subject: [PATCH 11/14] (tests) Update Test Package to have description

This updates the `test-chocolateypath` package to have a description and
removes the unneeded comments. This is related to a GitLab MR that noted
these things when bringing this package into the internal repository.

This reverts commit ffd9aab4b40dc8b47b84de5f3ce91ea22fda7a6d.

This adds logic to the Invoke-Tests file to output if a package failed
fail to pack. This allows for improved developer experience by
indicating if packages fail to build. This also allows impromptu
improvement to the developer experience by allowing simple changes to
the script to throw in place of outputting an errorand thus not
allowing tests to run without the full set of test packages.

-This is a nuspec. It mostly adheres to https://docs.nuget.org/create/Nuspec-Reference. Chocolatey uses a special version of NuGet.Core that allows us to do more than was initially possible. As such there are certain things to be aware of:
-
-* the package xmlns schema url may cause issues with nuget.exe
-* Any of the following elements can ONLY be used by choco tools - projectSourceUrl, docsUrl, mailingListUrl, bugTrackerUrl, packageSourceUrl, provides, conflicts, replaces
-* nuget.exe can still install packages with those elements but they are ignored. Any authoring tools or commands will error on those elements

-<!-- You can embed software files directly into packages, as long as you are not bound by distribution rights. -->
-<!-- * If you are an organization making private packages, you probably have no issues here -->
