The CreateEndToEndTestPackage.ps1 script generates a zip file that contains all the details needed for running End-to-End test. This zip file can also be generated by the build.ps1 script. Note that the scripts assume certain relative paths that are correct within the zip, but may not work if you attempt to use the scripts from the repo location.

NOTE: To ensure that all tests are runnable, you may need to update Visual Studio with tests vs config.

Running the tests

These tests run on the Visual Studio instance you need to test. They do not need Xunit or any other runner.

Create or download the end-to-end test ZIP file and extract it to a directory. It is recommended you extract the files in the artifacts directory at the repo root.
Run SetupFunctionalTests.ps1. This step is executed once per machine.
Start the Visual Studio instance you want to test. This can be a regular Visual Studio instance, with or without a VSIX that you want to test installed, but it can also be an experimental Visual Studio instance you want to debug.
Open the Package Manager Console and load the module from the unzipped end-to-end test package, NuGet.Tests.psm1, by running Import-Module <NuGet.Tests.psm1 file path>.
Run a test:
- Run-Test <TestName> - The test name is the function name without a prefix Test-.
- Run-Test <FileName> - The file name is a filename from the generated zip file.
- Run-Test - Runs all tests the runner can discover based on the relative file location.

Debugging End-to-End tests

Load the experimental instance of Visual Studio.
Find the code in question, and set your breakpoints.
Follow the steps for running the tests. Import the scripts in the experimental instance Package Manager Console.
