Maven plugin to generate AssertJ assertions

Overview

This plugin can generate AssertJ assertions for your own classes via maven (it is based on assertj-assertions-generator).

Let's say that you have a Player class with name and team attributes, the plugin is able to create a PlayerAssert assertions class with hasName and hasTeam assertions, to write code like :

assertThat(mvp).hasName("Lebron James").hasTeam("Miami Heat");

The plugin can be launched with command mvn generate-test-sources (or simply mvn test) or with any IDE that supports maven. By default, it generates the assertions source files in target/generated-test-sources/assertions as per maven convention (but this can be changed - see below).

Example of plugin execution:
