AssertStatement (Groovy 6.0.0-alpha-1)

org.codehaus.groovy.ast.stmt.AssertStatement

```
public class AssertStatement
extends Statement
```
Represents an assert statement that enforces a condition with an optional error message. An assert statement evaluates a boolean condition and throws an AssertionError if the condition is false. An optional message expression may be provided to customize the error message. Assert statements are typically used to verify invariants and debug assumptions.
Example: assert i != 0 : "should never be zero"
