Assertj assertions generator gradle plugin

A gradle plugin with task to generate assertions using AssertJ Assertions Generator.

The task generateAssertions will by default run after classes and before compileTestJava

Requirements

Gradle version >= 7.1

Configuration

plugins {
  id "com.github.fhermansson.assertj-generator" version "1.1.3"
}

assertjGenerator {
    classOrPackageNames = ['com.example.model']
}

The assertjGenerator extension configures the generateAssertions task, and provides default values for additional tasks of type com.github.fhermansson.gradle.assertj.plugin.GenerateAssertions.

Properties

Property	Type	Default	Description
classOrPackageNames	String[]	[]	Class or package names you want to generate assertions for
entryPointPackage	String	null	Destination package for entry point classes. The generator will choose if null
outputDir	Object	src/[testSourceSet.name]/generated-java	Where to put the generated classes. Will be resolved with project.file(outputDir)
sourceSet	SourceSet	sourceSets.main	The sourceSet containing classes that assertions should be generated for. This task will depend on the classes task for this sourceSet.
testSourceSet	SourceSet	sourceSets.test	The target sourceSet for assertions. outputDir will be added to the srcDirs of this sourceSet, and the compileJava, compileKotlin and compileGroove tasks for the sourceSet will depend on this task.
entryPointTypes	AssertionsEntryPointType[]	['STANDARD']	Types of entry point classes to generate. Possible values: 'STANDARD', 'SOFT', 'BDD', 'JUNIT_SOFT', 'BDD_SOFT', 'JUNIT_BDD_SOFT', 'AUTO_CLOSEABLE_SOFT', 'AUTO_CLOSEABLE_BDD_SOFT'
entryPointInherits	boolean	true	Entry point classes inherit from core Assertj classes
cleanOutputDir	boolean	true	Remove all files in outputDir before generating assertions.
excludes	String[]	[]	Regexes for classes to be excluded
useJakartaAnnotations	boolean	false	Use @jakarta.annotation.Generated instead of @javax.annotation.Generated

How to create additional tasks

In this example a task generateOtherAssertions is added to the project, generating assertions for an other sourceSet. Both generateOtherAssertions and generateAssertions will generate STANDARD and SOFT entry points because generateOtherAssertions will default to values from the assertjGenerator extension.

assertjGenerator {
    classOrPackageNames = ['com.example.model']
    entryPointTypes = ['STANDARD', 'SOFT']
}

import com.github.fhermansson.gradle.assertj.plugin.GenerateAssertions

task generateOtherAssertions(type: GenerateAssertions) {
     classOrPackageNames = ['com.other.model']
     sourceSet = sourceSets.other
     testSourceSet = sourceSets.otherTest
 }
