fluent-assert SKILL.md skillA
fluent-assert from ahoo-wang/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Write and refactor Kotlin assertions with FluentAssert's AssertJ-backed `.assert()` extensions and `assertThrownBy`. Use when a project depends on `fluent-assert-core`, the user asks for FluentAssert, or the user asks to migrate direct AssertJ calls to FluentAssert; covers JUnit and Wow/SagaSpec tests, nullable values, supported JDK types, collections, time, futures, predicates, exceptions, recursive comparison, and custom `AssertProvider` types.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FluentAssert
Use FluentAssert for Kotlin assertions in this repository and in downstream Kotlin test examples. Prefer the Kotlin extension style over direct AssertJ calls.
## Core Rule
```kotlin
import me.ahoo.test.asserts.assert
actual.assert().isEqualTo(expected)
```
Avoid `assertThat(actual)` in ordinary test code. FluentAssert keeps nullable receivers natural:
```kotlin
val name: String? = null
name.assert().isNull()
```
## Common Patterns
| Need | Pattern |
|---|---|
| Primitive/string/object | `value.assert().isEqualTo(expected)` |
| Collection/list | `items.assert().hasSize(2).contains("a")` |
| Map | `map.assert().hasSize(2).containsEntry("a", 1)` |
| Nullable value | `value.assert().isNull()` or `value.assert().isNotNull()` |
| Exception lambda | `assertThrownBy<IllegalArgumentException> { call() }.hasMessage("bad")` |
| Existing exception | `throwable.assert().hasMessageContaining("bad")` |
| LocalDate/YearMonth month | `date.assert().hasMonth(Month.APRIL)` |
| CompletableFuture success/failure | `completableFuture.assert().isCompletedWithValue(value)` / `.isCompletedExceptionally()` |

How to install
mdr add ahoo-wang/skills/fluent-assert@sha256:d1ffe6c4fa7e9f77The line at the top of this page pins the label git:20261011.07cdeb3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
