# assertj
|
|
|
|
Companion code for the ankurm.com post *AssertJ Complete Guide: Soft Assertions, Recursive Comparison and Custom Assertions*.
|
|
|
|
| Component | Version |
|
|
|---|---|
|
|
| AssertJ Core | 3.27.7 (GA, 2026-01-24; `4.0.0-M1` also exists on Maven Central but is a milestone) |
|
|
| JUnit | 6.1.3 |
|
|
| assertj-assertions-generator-maven-plugin | 2.2.0 (last release, 2019) |
|
|
| JDK | 25 (Temurin 25.0.5+8) |
|
|
|
|
```bash
|
|
./scripts/run-all.sh # runs every test and regenerates output/*.txt
|
|
```
|
|
|
|
Each test writes a transcript to `output/` and asserts the same facts, so every message quoted in the post fails the build if it stops being true. Two things in the output are not stable between runs: `Customer@<hash>` identity hashes in `14-isEqualTo-without-equals.txt`.
|
|
|
|
| Test | Output files | Topic |
|
|
|---|---|---|
|
|
| `BasicAssertionsTest` | 01-04 | failure messages, forgotten terminal call, BigDecimal and double |
|
|
| `CollectionAssertionsTest` | 05-08 | contains family, extracting, tuples, allSatisfy, maps |
|
|
| `ExceptionAssertionsTest` | 09 | assertThatThrownBy, cause chain, wrong-message output |
|
|
| `SoftAssertionsTest` | 10-13 | hard vs soft, forgotten `assertAll()`, NPE after a soft failure, JUnit extension |
|
|
| `RecursiveComparisonTest` | 14-17 | no-equals problem, DTO vs entity, difference report, ignoring and comparators |
|
|
| `CustomAssertionsTest` | 18-19 | hand-written `InvoiceAssert`, `Condition` |
|
|
| `GeneratedAssertionsTest` | 20-24 | generated `OrderAssert`, generated soft entry point, javax.annotation failure |
|
|
| `scripts/capture-generator.sh` | 22-25 | generator file list, javax.annotation compile error, the same tests on `4.0.0-M1` |
|
|
|
|
The `pom.xml` runs `assertj-assertions-generator-maven-plugin` on `lab.assertj.domain` before tests compile. It still emits `@javax.annotation.Generated`, so `javax.annotation-api` is a test dependency; `scripts/capture-generator.sh` removes it in a scratch copy to record the compiler error.
