A curated list of strings with a high probability of causing issues when used as user input, provided as newline-delimited text and JSON files. It is intended for automated and manual QA testing to expose string-handling and validation bugs.

Use cases

• test form inputs with problematic strings
• fuzz user input handling with edge-case unicode
• find string validation bugs in my app
• generate adversarial test data for QA
• test how my API handles emoji and special characters

When to choose

• you need a ready-made list of tricky input strings for QA or automated tests
• you want to check unicode, encoding, and injection edge cases in software you own

When to avoid

• you need formal security or penetration testing rather than input edge-case checks
• you need a programmatic fuzzing tool rather than a static string list
