Internal Test: Clearly contrasts the rule-level invalidation of `Minimum` with the transformer-level invalidation of `GlobalMinimum`.
Internal Test: Combines `@StartAfter` and `@StopAfter` to retrieve a specific 'page' of results (matches 3 through 7).
Internal Test: Compares the behavior of `Maximum` and `GlobalMaximum` at different thresholds to validate their distinct scopes of invalidation.
Internal Test: Compares the behavior of Maximum (rule-level) and GlobalMaximum (transformer-level) invalidation.
Internal Test: Contrasts a token-aware uCalc replacement with a character-aware regex replacement to highlight safety.
Internal Test: Demonstrates error recovery by having an error handler resume execution after a custom error is raised.
Internal Test: Demonstrates how changing an operator's precedence at runtime affects the parsing of subsequent expressions.
Internal Test: Implements a `ShortCircuitOr` function to prove that the second argument is not evaluated if the first is true, using side effects (counters) for verification.
Internal Test: Implements C-style hexadecimal literals (e.g., 0xFF) by adding a new token rule and a token transformation.
Internal Test: Removes the core alphanumeric token to verify that the tokenizer falls back to character-by-character tokenization.
Internal Test: Tests programmatic updates to a variable from host code in a loop, a common high-performance pattern.
Internal Test: Uses integer tags to programmatically categorize matches and process them differently in a loop.
Internal Test: Verifies advanced formatting of the trace output using `ListFormat` to create a custom, detailed step-by-step log.
Internal Test: Verifies behavior for patterns at the end of the string and patterns that are not found.
Internal Test: Verifies correct name retrieval for symbolic operators, internal tokens, and empty items.
Internal Test: Verifies correct precedence with overlapping patterns and confirms that re-running Find produces the same results.
Internal Test: Verifies correct results with multiple variables and a function call within a tight loop using a pre-parsed expression.
Internal Test: Verifies instance isolation by ensuring Tokens collections from different uCalc instances correctly resolve to their respective parents.
Internal Test: Verifies precedence and traversal of rules with different patterns but the same starting anchor ('Testing').
Internal Test: Verifies rule precedence and tag retrieval by traversing the overload chain with NextOverload.
Internal Test: Verifies that `{@@Eval}` can correctly parse and evaluate an expression that is itself captured from the text.
Internal Test: Verifies that a built-in function using `ByHandle` arguments can correctly modify the state of variables passed to it.
Internal Test: Verifies that a rule defined in a nested LocalTransformer correctly resolves its parent to the root uCalc instance.
Internal Test: Verifies that any rule not on the root transformer is considered a child, regardless of nesting depth.
Internal Test: Verifies that descriptions are copied when token sets are imported, but remain independent afterward.
Internal Test: Verifies that multi-pass transformations work correctly when `RewindOnChange` is enabled for the entire rule set.
Internal Test: Verifies that only the division by zero flag is affected, while other floating-point exceptions like overflow remain unchanged by default.
Internal Test: Verifies that releasing a rule correctly 'un-shadows' a previously defined rule with the same pattern.
Internal Test: Verifies that requesting an out-of-bounds index for a token type returns an empty item.
Internal Test: Verifies that the `subMatchGroup` parameter correctly extracts a capture group's content and that `ItemIs::QuotedText` works as expected.
Internal Test: Verifies that the correct parent is returned when using a nested LocalTransformer, confirming hierarchical integrity.
Internal Test: Verifies that the correct pattern string is returned for rules created with both FromTo() and Pattern(), including complex syntax.
Internal Test: Verifies that the count updates correctly after Add() and Clear() operations, demonstrating the dynamic nature of the collection.
Internal Test: Verifies that the description property is correctly copied when a Transformer is cloned.
Internal Test: Verifies that the error state is correctly cleared after a subsequent successful operation.
Internal Test: Verifies that the parent uCalc instance can be retrieved even from an empty Matches collection.
Internal Test: Verifies the 'live view' behavior by modifying an extracted block and showing the change reflected in the parent string.
Internal Test: Verifies the filtering of nested matches using RootLevelOnly and InnermostOnly options.
Internal Test: Verifies the LIFO precedence order and the return value for a token not present in the collection.
