Hello, Tracetest Community! 👋

We are thrilled to share the latest updates and exciting news from the Tracetest community! Take a look at what's happened in the last month. 👇

## Hot tip of the day!

### Filter Selectors by Attributes

The easiest way of filtering spans to apply an assertion to is to use the span's attributes. This is how you would filter all spans of type `http`:

```css
span[tracetest.span.type="http"]
```

This would select only the `http` spans in a distributed trace.


You can then create assertions that look at all matching spans, verifying that all status codes are equal to `200`.
