Runnable companion code for the testing posts on [ankurm.com](https://ankurm.com).

| Module | Post | Stack |
|---|---|---|
| [`mockito/`](mockito) | Mockito 5 Deep Dive: Static, Final and Constructor Mocking, ArgumentCaptor and Strict Stubs | Mockito 5.24.0, JUnit 6.1.3, JDK 25 |
| [`junit-6-migration/`](junit-6-migration) | JUnit 5 to 6 Migration: What Was Removed, What Changed and How to Upgrade | JUnit 5.14.4 and 6.1.3, JDK 25 |
| [`assertj/`](assertj) | AssertJ Complete Guide: Soft Assertions, Recursive Comparison and Custom Assertions | AssertJ 3.27.7, JUnit 6.1.3, JDK 25 |
| [`instancio/`](instancio) | Instancio: Generate Realistic Test Data Automatically in Java | Instancio 6.1.0, JUnit 6.1.3, JDK 25 |
| [`gatling-spring-boot/`](gatling-spring-boot) | Load Testing Spring Boot with Gatling's Java DSL (and How It Compares to k6) | Gatling 3.16.0, Spring Boot 4.1.2, k6 v2.3.0, JDK 25 |

Every module keeps the real output of its tests in `output/`. Each test writes the transcript and asserts the same facts, so the numbers in the posts fail the build if they stop being true.
