description: See how Visual Studio Code and its extensions helps you run and debug your Pester tests directly inside the editor | ||

### VSCode improvements | ||
Using Visual Studio Code with the latest [PowerShell extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.PowerShell) provides a great experience for writing PowerShell code. The extension includes Pester-specific features to improve the way you write, run and debug Pester tests. | ||
|
||
#### Use legacy code lens | ||
### Code lens | ||
|
||
With Pester 5 it is finally possible to run and debug just a single test in VSCode! | ||
With the `Pester: Code Lens` setting enabled, VSCode will show `Run tests` or `Debug tests` links above your Pester blocks for quick execution. Starting with Pester 5 this also works on individual tests. You can even run tests that are marked as skipped by running them individually. | ||
|

|
||
In the latest [PowerShell](https://marketplace.visualstudio.com/items?itemName=ms-vscode.PowerShell) extension for VSCode you can enable Use Legacy Code Lens option which will enable `Run tests` on all `Describe`, `Context` and `It` blocks. You can run a whole block, any child block, or any test individually. You can also run tests that are marked as skipped by running them individually. | ||
To enable the improved code lens for Pester 5 you need to disable the "Use Legacy Code Lens" setting which is enabled by default. | ||
|
||
Actually there is a bug, and the option is called Enable Legacy Code Lens, and is enabled by default and should be disabled for Pester 5. 😁 Take advantage of this and go try it right now! | ||
1. In Visual Studio Code, open **File | Preferences | Settings** (<kbd>⌘/Ctrl</kbd> + <kbd>,</kbd>) | ||
2. In the **Settings** window, navigate to the **Extensions | PowerShell** section. | ||
3. Uncheck the **Pester: Use Legacy Code Lens** checkbox. | ||
4. Close the **Settings** window. | ||
|
||
#### Output verbosity | ||
### Output verbosity | ||
|
||
You can specify verbosity in VSCode, to see normal or detailed output, or to take it from PesterPreference. This also works for Pester 4! | ||
You can control the output verbosity level in VSCode output, or let it inherit from PesterPreference. | ||
|
||

|
||
### Navigation | ||
|
||
Pester-blocks are recognized by the PowerShell-extension to simplify navigation in your test files. | ||
|
||
- The Outline panle shows an overview of your Pester-blocks.<br/> | ||

|

- Your current location in easily identified using breadcrumbs or the sticky scroll features.<br/> | ||
![Shows nested blocks as sticky lines above the current line in the editor](images/vscode-breadcrumbs.png) | ||
|
||
- `Context`, `Describe` and `It` blocks are all searchable using Go to symbol commands.<br/> | ||
