Cashtags don’t need to be true stock ticker symbols, $BSKY works just fine.

New facet just dropped, #cashtags like $GOOG and $AAPL. How does your app handle these?

Quote repost with 4 photos and 4 embedded photos

Quote repost with embedded external link

Quote repost with embedded video

Quoting a quote repost, quoteception... How would you render this?

This

line

It

how

that

Does
your

How are line breaks preserved?

```
Very long code block that tests how clients handle code formatting with extended content that might wrap or require horizontal scrolling in the interface.

function longFunction() {
const veryLongVariableName = "testing horizontal scroll";
return veryLongVariableName.repeat(10);
}
```

Testing conflicts: #hashtag vs # header, @mention vs @ symbol, *emphasis* vs asterisks

Testing edge cases:
**bold text with `code inside`**
*italic with ~~strikethrough~~ inside*
`code with **attempted bold** inside`

Unclosed **bold formatting
Mismatched *italic formatting**
Invalid `code formatting

How does your parser handle malformed markdown?

Testing escaped markdown: \*not bold\* \`not code\` \#not header - do backslashes prevent formatting?

**Bold** post with *italics* and `code` plus ~~strikethrough~~ and [a link](bsky.app) - kitchen sink test!

| Column 1 | Column 2 | Column 3 |
|----------|----------|----------|
| Cell 1 | Cell 2 | Cell 3 |
| Data A | Data B | Data C |

Table rendering test - most clients won't support this.

 - does your client handle markdown image syntax?

[Link with text](bsky.app) and [another link](github.com/bluesky-social) - do these render as clickable links?

Alternative syntax:
***
Does this create a visual separator?

Unordered list test:
- Item one
- Item two
- Nested item
- Item three

Ordered list test:
1. First item
2. Second item
3. Third item

# H1 Header Test
## H2 Header Test
### H3 Header Test
Do these render as headers or plain text with symbols?

Testing syntax highlighting:
```javascript
const test = () => {
return "syntax highlighting test";
};
```

Testing code blocks:
```
function hello() {
console.log("Does your app render this as a code block?");
}
```

Testing `inline code` formatting and multiple `code snippets` in one post. Monospace rendering test.

Testing ~~strikethrough text~~ - does your client support this markdown feature?

Testing ***bold and italic*** together, plus **bold with *italic* inside** and *italic with **bold** inside*.

Testing *italic text* and _alternative italic_ syntax. How does your app handle emphasis formatting?

Testing **bold text** and __alternative bold__ syntax. Does your client render these as bold or show the asterisks/underscores?
