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) |
./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.
