+# Add edge case tests for exclusiveMinimum and exclusiveMaximum keywords
+
+The `exclusiveMinimum` and `exclusiveMaximum` test files currently contain only a single test case each across all draft versions. Coverage is limited to basic positive floats (e.g. `exclusiveMinimum: 1.1`, `exclusiveMaximum: 3.0`), with no tests for zero, negatives, integer boundaries, very large or very small numbers, or interaction with `minimum` / `maximum`. Expanding these tests would help validator implementations handle boundary conditions correctly and align coverage with the richer edge cases already present in `minimum.json` and `maximum.json`.
+
+---
+
+### Motivation
+
+Implementations need to correctly handle exclusive bounds in a variety of numeric scenarios. The specification defines `exclusiveMinimum` and `exclusiveMaximum` for numeric validation; the suite should exercise integer boundaries, zero, negative numbers, and (where appropriate) extreme values. Tests that combine `exclusiveMinimum`/`exclusiveMaximum` with `minimum`/`maximum` would also clarify expected behavior when both are present. Better coverage here reduces the risk of validators misbehaving on real-world schemas that use these keywords.
+
+### Current tests
+
+Each of the following files contains only **one test case** (one schema plus its tests):

+
+### Proposed additions
+
+- **Integer boundaries:** Test cases where the bound is an integer (e.g. `exclusiveMinimum: 0`, `exclusiveMaximum: 10`) and instances use both integer and float representations (e.g. `0` vs `0.0`, `10` vs `10.0`) to assert correct exclusive comparison.
+- **Zero:** Explicit tests for zero as either the bound or the instance (e.g. `exclusiveMinimum: 0` with valid `0.1` and invalid `0`; `exclusiveMaximum: 0` with valid `-0.1` and invalid `0`).
+- **Negative numbers:** Test cases with negative bounds and/or negative instances (e.g. `exclusiveMinimum: -2`, `exclusiveMaximum: -1`) to cover signed comparisons.
+- **Very large and very small numbers:** Edge cases with large or small finite values (within normal JSON number range). Implementation-specific overflow behavior may follow existing optional patterns (e.g. [tests/draft2020-12/optional/bignum.json](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/tests/draft2020-12/optional/bignum.json), [tests/draft2020-12/optional/float-overflow.json](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/tests/draft2020-12/optional/float-overflow.json)) where relevant.
+- **Interaction with `minimum` / `maximum`:** Test cases where both `minimum` and `exclusiveMinimum`, or both `maximum` and `exclusiveMaximum`, appear in the same schema, to assert that implementations apply the exclusive bound correctly when used together.
+
+### Implementation notes
+
+- Follow the [CONTRIBUTING](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/CONTRIBUTING.md) guidelines: use **minimal** schemas (only keywords under test) and prefer simpler instances where possible.
+- Include both **valid** and **invalid** instances for each new test case where the schema allows either outcome; see the [README](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/README.md) test structure.
+- Add new test cases to **all applicable draft versions** (draft-07, draft-2019-09, draft-2020-12, v1), with any draft-specific adjustments (e.g. `$id` vs `id`, `$schema` usage) as needed.
+- Before adding tests, review the spec sections for [exclusiveMinimum](https://json-schema.org/draft/2020-12/draft-bhutton-json-schema-validation-01#name-exclusiveminimum) and [exclusiveMaximum](https://json-schema.org/draft/2020-12/draft-bhutton-json-schema-validation-01#name-exclusivemaximum) to ensure the new cases match specified behavior.

+**Title:** Add tests for empty and null value edge cases
+
+The suite does not yet systematically cover empty arrays, empty objects, empty strings, and `null` instances across the relevant keywords. These are common real‑world edge cases, and adding targeted tests would help validators behave consistently. Many core keywords may be affected (e.g. `type`, `minItems` / `maxItems`, `minLength` / `maxLength`, `required`), but the scope can stay descriptive; the gaps are straightforward to identify, the tests are simple to write and follow existing patterns, and they are a good way to learn the test structure and contributing guidelines.
+
+### Proposed scope
+
+- **Review existing tests** for key structural and validation keywords and identify where empty/null cases are missing (empty `[]`, `{}`, `""`, and `null` as instance values).
+- **Add minimal schemas plus instances** that include those values, with both valid and invalid outcomes where the schema allows either.
+- **Follow existing test patterns and directory structure**; keep new tests small and focused, and add them to all applicable draft versions per [CONTRIBUTING](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/CONTRIBUTING.md).

+# Add boundary value tests for numeric keywords
+
+The current numeric keyword tests (`minimum`, `maximum`, `multipleOf`, `exclusiveMinimum`, `exclusiveMaximum`) have limited boundary-value coverage for very large/small numbers and precision limits. Expanding these tests would help ensure validators handle numeric edge cases correctly across different implementations and platforms.

+- Large integers near JavaScript's `Number.MAX_SAFE_INTEGER` (2^53 − 1) and `Number.MIN_SAFE_INTEGER` (−2^53 + 1) for `minimum`/`maximum`/`exclusiveMinimum`/`exclusiveMaximum`
+- Very small floating-point numbers near zero (e.g., 1e-308, -1e-308) for boundary validation
+- Precision limit edge cases for `multipleOf` (e.g., very small divisors, floating-point precision boundaries)
+- Large floating-point numbers approaching implementation limits
+
+## Implementation notes
+
+- Use minimal schemas focusing on the numeric keyword being tested
+- Add tests to all applicable drafts (draft-03 through draft-2020-12, and v1 where the keyword exists)
+- Tests for implementation-specific numeric precision limits (e.g., beyond IEEE 754 double precision) should be placed in `optional/` directories, following the pattern of [`optional/bignum.json`](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/tests/draft2020-12/optional/bignum.json) and [`optional/float-overflow.json`](https://github.com/json-schema-org/JSON-Schema-Test-Suite/blob/main/tests/draft2020-12/optional/float-overflow.json)
