# Close-CatProject

## Synopsis

```powershell
Close-CatProject
```

## Parameters

None (common parameters only).

## What it does

Removes the open project from the module state and disposes the session behind it, releasing the connections it held. Nothing has to be closed before another `Open-CatProject` — opening replaces the previous project by itself — and ending the PowerShell session releases everything as well; `Close-CatProject` is for scripts that want to release data-source connections explicitly, or to make sure a later `Get-Cat*` cannot accidentally read a stale project.

After it, `Get-CatTestResultSummary` and `Get-CatTestResult` report `There is no CAT session active…` — the results of the last run go with the session.

## Output

Nothing. With `-Verbose`, what was removed.

## Errors

None. Calling it with no open project or no session is not an error.

## Examples

```powershell
Open-CatProject -Path 'D:\Testing\DwhTests.cat.yaml'
$summary = Invoke-CatTest
Close-CatProject
```
