From 2475936d1b6941edf2701ba55e419c1efad0fb7e Mon Sep 17 00:00:00 2001 From: Bogdan Szabo Date: Mon, 1 Dec 2025 09:31:19 +0100 Subject: [PATCH 01/99] Refactor assertion operations to utilize result objects for improved clarity and consistency - Updated `contain`, `endWith`, `equal`, `greaterOrEqualTo`, `greaterThan`, `lessOrEqualTo`, `lessThan`, `startWith`, and `throwable` operations to replace message handling with result object usage. - Enhanced result reporting by adding expected, actual, and negated values directly to the result object. - Removed unnecessary exception handling in result creation, simplifying the code structure. - Adjusted unit tests to reflect changes in expected output formatting for assertions. --- source/fluentasserts/core/array.d | 2 +- source/fluentasserts/core/asserts.d | 162 ++++++++++++++++ source/fluentasserts/core/base.d | 31 ++- source/fluentasserts/core/basetype.d | 8 +- source/fluentasserts/core/evaluation.d | 17 +- source/fluentasserts/core/evaluator.d | 183 +++++++++++++----- source/fluentasserts/core/expect.d | 45 +++-- source/fluentasserts/core/lifecycle.d | 25 ++- source/fluentasserts/core/message.d | 6 + .../core/operations/approximately.d | 58 ++++-- .../core/operations/arrayEqual.d | 14 +- source/fluentasserts/core/operations/beNull.d | 13 +- .../fluentasserts/core/operations/between.d | 48 ++--- .../fluentasserts/core/operations/contain.d | 153 +++++++-------- .../fluentasserts/core/operations/endWith.d | 37 ++-- source/fluentasserts/core/operations/equal.d | 40 ++-- .../core/operations/greaterOrEqualTo.d | 29 +-- .../core/operations/greaterThan.d | 29 +-- .../core/operations/lessOrEqualTo.d | 25 +-- .../fluentasserts/core/operations/lessThan.d | 31 +-- .../fluentasserts/core/operations/registry.d | 6 +- .../fluentasserts/core/operations/startWith.d | 37 ++-- .../fluentasserts/core/operations/throwable.d | 104 +++++----- source/fluentasserts/core/results.d | 171 ++++++++++++++-- source/fluentasserts/core/string.d | 14 +- 25 files changed, 864 insertions(+), 424 deletions(-) create mode 100644 source/fluentasserts/core/asserts.d diff --git a/source/fluentasserts/core/array.d b/source/fluentasserts/core/array.d index e4928661..c6a24f34 100644 --- a/source/fluentasserts/core/array.d +++ b/source/fluentasserts/core/array.d @@ -823,7 +823,7 @@ unittest { }).should.throwException!TestException.msg;

Operations are functions that receive an `Evaluation` and modify it to indicate success or failure. The operation sets the `expected` and `actual` fields on `evaluation.result` when there is a failure. You can check any of the built in operations for a reference implementation. ```d -IResult[] customOperation(ref Evaluation evaluation) @safe nothrow { - ... +void customOperation(ref Evaluation evaluation) @safe nothrow { + // Perform your check + bool success = /* your logic */; + + if (!success) { + evaluation.result.expected = "expected value description"; + evaluation.result.actual = "actual value description"; + } } ``` @@ -148,14 +154,13 @@ Once the operation is ready to use, it has to be registered with the global regi ```d static this() { - /// bind the type to different matchers + // bind the type to different matchers Registry.instance.register!(SysTime, SysTime)("between", &customOperation); Registry.instance.register!(SysTime, SysTime)("within", &customOperation); - /// or use * to match any type + // or use * to match any type Registry.instance.register("*", "*", "customOperation", &customOperation); } - ``` ## Registering new serializers diff --git a/api/equal.md b/api/equal.md index d877be35..32538840 100644 --- a/api/equal.md +++ b/api/equal.md @@ -5,7 +5,6 @@ Asserts that the target is strictly == equal to the given val.

00:00:00 2001 From: Bogdan Szabo Date: Sun, 7 Dec 2025 23:37:17 +0100 Subject: [PATCH 19/99] feat: Add introduction and philosophy documentation for fluent-asserts - Created introduction.mdx to provide an overview and quick start guide for fluent-asserts. - Added philosophy.mdx outlining the 4 Rules of Simple Design and the rationale behind fluent-asserts. - Updated index.mdx to highlight the benefits of using fluent-asserts with examples. - Introduced custom CSS styles for documentation to enhance readability and aesthetics. - Added TypeScript configuration for improved type checking in documentation. - Updated dub.json to reflect the new copyright year. - Enhanced the Assert struct with new methods for exception handling, memory allocation checks, and string assertions. - Added unit tests for new Assert methods to ensure functionality. --- .github/workflows/docs.yml | 67 + .gitignore | 6 + docs/astro.config.mjs | 64 + docs/package-lock.json | 7428 +++++++++++++++++

Passes All Tests + +> The code must work correctly + +Good tests are the foundation of reliable software. When a test fails, you need to understand why immediately. fluent-asserts provides clear, detailed failure messages that show exactly what was expected versus what was received, making debugging fast and straightforward. + +```d +// When this fails, you see: +// Expected: "hello" +// Actual: "world" +expect("world").to.equal("hello"); +``` + +### 2.

New team members can understand what's being tested without additional comments. Your tests become living documentation of your system's expected behavior. + +### 3. No Duplication (DRY) + +> Don't Repeat Yourself + +fluent-asserts gives you reusable assertion operations that work consistently across all types. Instead of writing custom comparison logic for each situation, you use the same expressive API everywhere.

Postblit increments the reference count + +This happens automatically - **you don't need to call any special methods** when returning HeapString or structs containing HeapString from functions. + +### Nested Structs + +When a struct contains members with postblit constructors, D automatically calls postblit on each member: + +```d +struct ValueEvaluation { + HeapString strValue; // Has postblit + HeapString niceValue; // Has postblit + + // D automatically calls strValue.this(this) and niceValue.this(this) + // when ValueEvaluation is blitted + this(this) @trusted nothrow @nogc { + // Nested postblits handle ref counting automatically + } +} +``` + +## Legacy: prepareForBlit() + +For backwards compatibility and edge cases, `prepareForBlit()` and `incrementRefCount()` methods are still available: + +```d +/// Manually increment ref count (for edge cases) +void incrementRefCount() @trusted @nogc nothrow { + if (_refCount) { + (*_refCount)++; + } +} +``` + +In most cases, you should **not need to call these methods** - the postblit constructor handles everything automatically. + +## Memory Initialization + +HeapData zero-initializes allocated memory using `memset`. This prevents garbage values in uninitialized struct fields from causing issues with reference counting: + +```d +static HeapData create(size_t initialCapacity) @trusted @nogc nothrow { + HeapData h; + h._data = cast(T*) malloc(cap * T.sizeof); + + // Zero-initialize to prevent garbage ref counts + if (h._data) { + memset(h._data, 0, cap * T.sizeof); + } + + h._refCount = cast(size_t*) malloc(size_t.sizeof); + if (h._refCount) *h._refCount = 1; + + return h; +} +``` + +## Assignment Operators + +HeapData provides both lvalue and rvalue assignment operators: + +### Lvalue Assignment (from another variable) + +```d +void opAssign(ref HeapData rhs) @trusted @nogc nothrow { + if (_data is rhs._data) return; // Self-assignment check + + // Decrement old ref count + if (_refCount && --(*_refCount) == 0) { + free(_data); + free(_refCount); + } + + // Copy and increment new ref count + _data = rhs._data; + _refCount = rhs._refCount;

We have completely rewritten the internal engine to be faster, lighter, and more flexible. While the public API remains largely familiar, the internal architecture has shifted significantly to support `@nogc` and manual memory management. + +This guide covers everything you need to know to upgrade your projects. + +## The Big Architectural Shifts + +Before diving into the code, it helps to understand why things changed. + +### 1. Memory Management Overhaul + +The most significant change in v2 is the move from D's Garbage Collector (GC) to manual memory management. While version 1 relied on the GC for dynamic allocations and assertion strings, version 2 utilizes `HeapString` and `HeapData` with Reference Counting. + +This shift brings several key benefits: + +- **@nogc contexts**: Use fluent-asserts throughout `@nogc` code +- **Performance**: Small Buffer Optimization (SBO) avoids allocations entirely for short strings +- **Lazy parsing**: Source code parsing only happens if an assertion fails, keeping your passing tests fast + +:::note +For most users, this is invisible. If you are extending the library, check out the [Memory Management](/guide/memory-management/) guide. +::: + +### 2. The New Evaluation Pipeline + +We moved from a class-based evaluation system to a lightweight struct-based system. `Evaluation` is now a struct, and results use `AssertResult` instead of the old interface-based system. + +## Breaking Changes + +If you are upgrading an existing codebase, watch out for these structural changes. + +### Module Restructuring + +We cleaned up the module hierarchy to be more logical. + +| Old Location (v1) | New Location (v2) | +|-------------------|-------------------| +| `fluentasserts.core.operations.equal` | `fluentasserts.operations.equality.equal` | +| `fluentasserts.core.operations.contain` | `fluentasserts.operations.string.contain` | +| `fluentasserts.core.operations.greaterThan` | `fluentasserts.operations.comparison.greaterThan` | +| `fluentasserts.core.operations.throwable` | `fluentasserts.operations.exception.throwable` | +| `fluentasserts.core.operations.registry` | `fluentasserts.operations.registry` | + +:::tip +If you import `fluent.asserts` or `fluentasserts.core.base`, you likely don't need to change anything! +::: + +### Serializers + +v2 uses `HeapSerializerRegistry` for `@nogc` compatible serialization. + +## New Features + +### 1. Centralized Configuration + +You now have a unified `FluentAssertsConfig` for both compile-time and runtime settings. + +```d +import fluentasserts.core.config; + +// Compile-time check +static if (fluentAssertsEnabled) { /* ... */ } + +// Runtime configuration +config.output.setFormat(OutputFormat.compact); +``` + +### 2. Output Formats + +Three output formats let you tailor assertion messages for your audience: + +- **Verbose** (default) - Human-friendly format with full context and source snippets +- **TAP** - Universal machine-readable format for CI/CD pipelines and test harnesses +- **Compact** - Token-optimized format for AI coding assistants like Claude Code + +```bash +# Use compact format for AI-assisted development +CLAUDECODE=1 dub test +``` + +See [Configuration](/guide/configuration/) for all the ways to set output formats. + +### 3. Context Data & Formatted Messages + +When debugging loops, you can now add context directly to the assertion chain. + +```d +// Formatted "Because" +foreach (i; 0 .. 100) { + result.should.equal(expected).because("iteration %s", i); +} + +// Key-Value Context +result.should.equal(expected) + .withContext("userId", userId) + .withContext("email", user.email); +``` + +See [Context Data](/guide/context-data/) for more examples. + +### 4. Memory Assertions + +You can strictly test your memory allocation behavior to ensure code uses the GC or remains `@nogc` compliant. + +```d +// Ensure code uses GC +expect({ auto arr = new int[100]; }).to.allocateGCMemory(); + +// Ensure code is @nogc compliant +expect({ int x = 42; }).not.to.allocateGCMemory(); +``` + +See [Memory Assertions](/api/callable/gcMemory/) for platform notes. + +## Migration Guide + +Follow these steps to upgrade your application to v2.0. + +### Step 1: Update Imports + +Most users will not need to take any action. Advanced users who import internal modules will need to update them to the new paths found in the breaking changes section. + +### Step 2: Update Custom Serializers + +If you registered custom serializers in v1, use `HeapSerializerRegistry`: + +```d +HeapSerializerRegistry.instance.register!MyType(&mySerializer); +``` + +### Step 3: Update Custom Operations + +If you wrote custom operations, note that the signature has changed. Operations now modify the `Evaluation` struct directly instead of returning `IResult[]`. + +See [Extending fluent-asserts](/guide/extending/) for the new patterns and examples. + +### Step 4: Verify @nogc + +If you use fluent-asserts in `@nogc` code, it should now work out of the box! Just ensure your custom extensions are also `@nogc` safe. + +## More New Features + +### Assertion Statistics + +Track how many assertions pass and fail across your test suite: + +```d +auto stats = Lifecycle.instance.statistics; +writeln("Passed: ", stats.passedAssertions); +writeln("Failed: ", stats.failedAssertions); +``` + +See [Assertion Statistics](/guide/statistics/) for detailed usage. + +### Recording Evaluations + +Capture assertion results programmatically without throwing: + +```d +auto evaluation = ({ + expect(5).to.equal(10); +}).recordEvaluation; + +// Inspect without failing +assert(evaluation.result.expected[] == "10"); +``` + +See [Recording Evaluations](/guide/introduction/#recording-evaluations) for more details. + +### Release Build Behavior + +Like D's built-in `assert`, fluent-asserts becomes a no-op in release builds for zero runtime overhead. You can override this with version flags. + +See [Release Build Configuration](/guide/configuration/#release-build-configuration) for details. + +## Getting Help + +If you get stuck: + +- Check the [API Reference](/api/) for current method signatures +- Examine the source code in `source/fluentasserts/operations/` for examples +- Open a ticket at [fluent-asserts/issues](https://github.com/gedaiu/fluent-asserts/issues) + +## Learn More + +Explore the documentation to get the most out of fluent-asserts v2: + +- [Installation](/guide/installation/) - Get started with fluent-asserts +- [Assertion Styles](/guide/assertion-styles/) - Learn the fluent API +- [Configuration](/guide/configuration/) - Output formats and build settings +- [Context Data](/guide/context-data/) - Debug assertions in loops +- [Assertion Statistics](/guide/statistics/) - Track pass/fail metrics +- [Memory Management](/guide/memory-management/) - Understand the `@nogc` internals +- [Core Concepts](/guide/core-concepts/) - How the evaluation pipeline works +- [Extending](/guide/extending/) - Create custom operations and serializers +- [API Reference](/api/) - Complete operation reference diff --git a/source/fluentasserts/core/evaluator.d b/source/fluentasserts/core/evaluator.d index bd24e5c5..00c2a25e 100644 --- a/source/fluentasserts/core/evaluator.d +++ b/source/fluentasserts/core/evaluator.d @@ -6,7 +6,6 @@ import fluentasserts.core.evaluation.eval : Evaluation, evaluate;
