 ## Usage

-Use TypeScript for best in class intellisense
+`@push.rocks/smartexpect` is a TypeScript library designed to manage expectations in your code effectively, improving testing readability and maintainability. Below are various scenarios showcasing how to use this library effectively across both synchronous and asynchronous code paths.

-## Contribution
+### Getting Started

-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+First, import `@push.rocks/smartexpect` into your TypeScript file:

-For further information read the linked docs at the top of this readme.
+```typescript
+import { expect, expectAsync } from '@push.rocks/smartexpect';
+```

+### Synchronous Expectations

-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+You can employ `expect` to create synchronous assertions:
+
+```typescript
+import { expect } from '@push.rocks/smartexpect';
+
+// Type assertions
+expect('hello').toBeTypeofString();
+expect(42).toBeTypeofNumber();
+expect(true).toBeTypeofBoolean();
+expect(() => {}).toBeTypeOf('function');
+expect({}).toBeTypeOf('object');
+
+// Negated assertions
+expect(1).not.toBeTypeofString();
+expect('string').not.toBeTypeofNumber();
+
+// Equality assertion
+expect('hithere').toEqual('hithere');
+
+// Deep equality assertion
+expect({ key: 'value' }).toEqual({ key: 'value' });
+
+// Regular expression matching
+expect('hithere').toMatch(/hi/);
+```
+
+### Asynchronous Expectations
+
+For asynchronous code, use the same `expect` function with the `.resolves` or `.rejects` modifier:
+
+```typescript
+import { expect } from '@push.rocks/smartexpect';
+
+const asyncStringFetcher = async (): Promise<string> => {
+  return 'async string';
+};
+
+const asyncTest = async () => {
+  // Add a timeout to prevent hanging tests
+  await expect(asyncStringFetcher()).resolves.withTimeout(5000).type.toBeTypeofString();
+  await expect(asyncStringFetcher()).resolves.toEqual('async string');
+};
+
+asyncTest();
+```
+
+### Navigating Complex Objects
+
+You can navigate complex objects using the `property()` and `arrayItem()` methods:
+
+```typescript
+const complexObject = {
+  users: [
+    { id: 1, name: 'Alice', permissions: { admin: true } },
+    { id: 2, name: 'Bob', permissions: { admin: false } }
+  ]
+};
+
+// Navigate to a nested property
+expect(complexObject)
+  .property('users')
+  .arrayItem(0)
+  .property('name')
+  .toEqual('Alice');
+
+// Check nested permission
+expect(complexObject)
+  .property('users')
+  .arrayItem(0)
+  .property('permissions')
+  .property('admin')
+  .toBeTrue();
+```
+
+### Advanced Assertions
+
+#### Properties and Deep Properties
+
+Assert the existence of properties and their values:
+
+```typescript
+const testObject = { level1: { level2: 'value' } };
+
+// Property existence
+expect(testObject).toHaveProperty('level1');
+
+// Property with specific value
+expect(testObject).toHaveProperty('level1.level2', 'value');
+
+// Deep Property existence
+expect(testObject).toHaveDeepProperty(['level1', 'level2']);
+```
+
+#### Conditions and Comparisons
+
+Perform more intricate assertions:
+
+```typescript
+// Numeric comparisons
+expect(5).toBeGreaterThan(3);
+expect(3).toBeLessThan(5);
+expect(5).toBeGreaterThanOrEqual(5);
+expect(5).toBeLessThanOrEqual(5);
+expect(0.1 + 0.2).toBeCloseTo(0.3, 10); // Floating point comparison with precision
+
+// Truthiness checks
+expect(true).toBeTrue();
+expect(false).toBeFalse();
+expect('non-empty').toBeTruthy();
+expect(0).toBeFalsy();
+
+// Null/Undefined checks
+expect(null).toBeNull();
+expect(undefined).toBeUndefined();
+expect(null).toBeNullOrUndefined();
+
+// Custom conditions
+expect(7).customAssertion(value => value % 2 === 1, 'Value is not odd');
+```
+
+#### Arrays and Collections
+
+Work seamlessly with arrays and collections:
+
+```typescript
+const testArray = [1, 2, 3];
+
+// Array checks
+expect(testArray).toBeArray();
+expect(testArray).toHaveLength(3);
+expect(testArray).toContain(2);
+expect(testArray).toContainAll([1, 3]);
+expect(testArray).toExclude(4);
+expect([]).toBeEmptyArray();
+expect(testArray).toHaveLengthGreaterThan(2);
+expect(testArray).toHaveLengthLessThan(4);
+
+// Deep equality in arrays
+expect([{ id: 1 }, { id: 2 }]).toContainEqual({ id: 1 });
+```
+
+#### Strings
+
+String-specific checks:
+
+```typescript
+expect('hello world').toStartWith('hello');
+expect('hello world').toEndWith('world');
+expect('hello world').toInclude('lo wo');
+expect('options').toBeOneOf(['choices', 'options', 'alternatives']);
+```
+
+#### Functions and Exceptions
+
+Test function behavior and exceptions:
+
+```typescript
+const throwingFn = () => { throw new Error('test error'); };
+expect(throwingFn).toThrow();
+expect(throwingFn).toThrow(Error);
+
+const safeFn = () => 'result';
+expect(safeFn).not.toThrow();
+```
+
+#### Date Assertions
+
+Work with dates:
+
+```typescript
+const now = new Date();
+const past = new Date(Date.now() - 10000);
+const future = new Date(Date.now() + 10000);
+
+expect(now).toBeDate();
+expect(now).toBeAfterDate(past);
+expect(now).toBeBeforeDate(future);
+```
+
+### Debugging Assertions
+
+The `log()` method is useful for debugging complex assertions:
+
+```typescript
+expect(complexObject)
+  .property('users')
+  .log() // Logs the current value in the assertion chain
+  .arrayItem(0)
+  .log() // Logs the first user
+  .property('permissions')
+  .log() // Logs the permissions object
+  .property('admin')
+  .toBeTrue();
+```
+
+### Customizing Error Messages
+
+You can provide custom error messages for more meaningful test failures:
+
+```typescript
+expect(user.age)
+  .setFailMessage('User age must be at least 18 for adult content')
+  .toBeGreaterThanOrEqual(18);
+```
+
+### Custom Matchers
+
+You can define your own matchers via `expect.extend()`:
+
+```typescript
+expect.extend({
+  toBeOdd(received: number) {
+    const pass = received % 2 === 1;
+    return {
+      pass,
+      message: () =>
+        `Expected ${received} ${pass ? 'not ' : ''}to be odd`,
+    };
+  },
+});
+
+// Then use your custom matcher in tests:
+expect(3).toBeOdd();
+expect(4).not.toBeOdd();
+```
+
+- Matcher functions receive the value under test (`received`) plus any arguments.
+- Must return an object with `pass` (boolean) and `message` (string or function) for failure messages.
+
+## Best Practices
+
+- **Human-readable assertions**: The fluent API is designed to create tests that read like natural language sentences.
+
+- **Precise error messages**: When tests fail, the error messages provide detailed information about what went wrong, including expected vs. actual values.
+
+- **Property path navigation**: Use the property path methods to navigate complex objects without creating temporary variables.
+
+- **Comprehensive testing**: Take advantage of the wide range of assertion methods to test various aspects of your code.
+
+- **Debugging with log()**: Use the `log()` method to see intermediate values in the assertion chain during test development.

+# Plan for Improving @push.rocks/smartexpect API
+
+This document captures the roadmap for evolving the `expect` / `expectAsync` API.
+
+## Phase 1: Unify Sync + Async
+- [x] Consolidate `expect` and `expectAsync` into a single `expect()` entry point.
+- [x] Introduce `.resolves` and `.rejects` chainable helpers for Promises.
+- [x] Deprecate `expectAsync`, provide migration guidance.
+
+## Phase 2: Timeout Helper
+- [x] Rename or wrap the existing `.timeout(ms)` to a more intuitive `.withTimeout(ms)`.
+
+## Phase 3: Custom Matchers
+- [x] Implement `expect.extend()` API for user-defined matchers.
+
+## Phase 4: TypeScript Typings
+- [ ] Enhance generic matcher types to infer narrow types after `.property()` / `.arrayItem()`.
+- [ ] Provide matcher overloads for primitive categories (string, number, array, etc.).
+
+## Phase 5: Namespaced Matchers
+- [ ] Group matchers under `.string`, `.array`, `.number`, etc. for discoverability.
+
+## Phase 6: Jest-Style Convenience
+- [x] Add `expect.any()` and `expect.anything()` matchers for use in `.toMatchObject()` patterns
+  (Snapshot matchers still TBD)
+
+The next items to tackle:
+
+3. Improve negation (`.not`) messaging
+   - Today `.not` simply flips pass/fail, but the failure message isn’t very descriptive. We should capture positive/negative message templates so e.g.
+     > expect(5).not.toBeGreaterThan(3)
+     emits:
+     "Expected 5 not to be greater than 3"
+
+4. Richer error output for objects/arrays
+   - Integrate a diff library (or extend `fast-deep-equal`) to show unified diffs between expected and actual values
+
+5. More built-in matchers
+   - toBeNaN(), toBeFinite()
+   - toBeWithinRange(min, max)
+   - toHaveKeys(...), toHaveOwnKeys(...)
+   - toThrowErrorMatching(/regex/), toThrowErrorWithMessage('…')
+   - string/array: toBeEmpty() alias
+   - object: toHaveOwnProperty() shorthand
+
+6. TypeScript-friendliness
+   - Enhance `.d.ts` so editors autocomplete namespace methods (e.g. `expect(x).string.`)
+   - Statically type matcher arguments to catch wrong types at compile time
+
+7. Async assertions and timeouts improvements
+   - Support `.not.resolves`, `.rejects.toThrow()`
+   - Provide clearer timeout errors (e.g. "Expected promise to resolve within …")
+
+8. Plugin/extension API
+   - Formalize `Assertion.extend()` plugin API for shipping matcher bundles
