In the tables below we use the following symbols:
- 🔍 - whether the diagnostic is enabled by default or not
- 📝 - the severity of the diagnostic
- 💡 - whether the diagnostic has an associated code fix or not
The severity of a diagnostic can the one of the following (in increasing severity):
- 💭 - indicates a severity of Hidden
- ℹ️ - indicates a severity of Info
⚠️ - indicates a severity of Warning- ❗ - indicates a severity of Error
Rules which enforce structural requirements on the test code.
