# Introduction

This is a sample Markdown document for testing the MarkdownExtractor.

## Features

The extractor should handle:

- YAML front matter extraction
- Heading structure
- **Bold text** and *italic text*
- Lists and other formatting

### Code Examples

        assertTrue(content.contains("author"));
        assertTrue(content.contains("John Doe"));

        // Verify metadata extraction
        assertNotNull(extractData.getValues("title"));
        assertEquals("Sample Document", extractData.getValues("title")[0]);
        assertNotNull(extractData.getValues("author"));
        assertEquals("John Doe", extractData.getValues("author")[0]);
    }

    public void test_getText_nested() {

        assertNotNull(titles);
        assertEquals("Sample Markdown Document", titles[0]);

        final String[] authors = extractData.getValues("frontmatter.author");
        assertNotNull(authors);
        assertEquals("John Doe", authors[0]);

        final String[] dates = extractData.getValues("frontmatter.date");
        assertNotNull(dates);
        assertEquals("2025-01-15", dates[0]);
    }

    public void testMultipleParamsWithSpecialCharacters() {
        CurlRequest request = new CurlRequest(Method.GET, "https://example.com");

        // Add params with special characters
        request.param("name", "John Doe").param("email", "******@****.***").param("query", "hello & goodbye").param("special", "100%");

        assertNotNull(request);
        assertEquals(Method.GET, request.method());
    }
