# Testing MsQuic
## Running the Tests
First [build](./BUILD.md). If you are trying to run the tests on a different machine from the one where you are building msquic, you can copy `artifacts` and `scripts` folders after building msquic over to that machine and run the below steps from there. Running kernel mode msquic and QUIC over XDP tests requires test signing enabled on the machine. It's also more convenient to be done on a machine/VM that's dedicated for testing in case something bugchecks the machine.
Prepare the machine:
```PowerShell
.\scripts\prepare-machine.ps1 -ForTest
```
Then all the tests can be run with:
```PowerShell
./scripts/test.ps1
```
> **Note**
> On Windows, `schannel` is the default TLS provider, but requires the latest Windows OS versions (Windows Server 2022 or Insider Preview) to function. If you don't have `schannel` use `openssl` to build and test.
```PowerShell
./scripts/test.ps1 -Tls openssl
```
Windows XDP datapath can be used unless a test explicitly specify loopback address by
```Powershell
./scripts/test.ps1 -UseXdp
```
By default this will run all tests in series, with no log collection. To include log collection for failed tests, run:
```PowerShell
./scripts/test.ps1 -LogProfile Full.Light
```
> **Note**
> On Windows, you will need to run Powershell as **Administrator** to get the logs.
If there are any failed tests, this will generate a directory for each failed test that includes the console output from running the test and any logs collected.
**Example Output** (Windows)
```PowerShell
PS F:\msquic> .\scripts\test.ps1

## PowerShell Script Arguments
There are a number of other useful arguments for `test.ps1`.
`Config <Debug/Release>` - The build configuration (**default**: `debug`) to test. Must have been built first.
`Arch <x86/x64/arm/arm64>` - The CPU architecture (**default**: `x64`) to test. Must have been built first.
`Tls <openssl/schannel>` - The TLS provider to use (**Windows default**: `schannel`, **Posix default**: `openssl`) to test. Must have been built first.
`Filter <GoogleTest filter>` - A filter for which tests to run. More details [here](https://google.github.io/googletest/advanced.html#running-a-subset-of-the-tests) on the syntax.
`ListTestCases` - Lists all the (optionally filtered) tests instead of running them.
`NoProgress` - Don't display progress during test execution.
`LogProfile <profile>` - The profile to use for logging. **TODO** - Add more here.
`KeepOutputOnSuccess` - Keep logs even if tests pass.
`Debugger` - Run with the debugger attached.
`InitialBreak` - Break in the debugger on initial attach/start.
`BreakOnFailure` - Break into the debugger for any test failures.
