### 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/>

- `Context`, `Describe` and `It` blocks are all searchable using Go to symbol commands.<br/>
