Introduction

Provides the following features, implemented using JUnit Jupiter’s Extension Model:

• BenchmarkExtension: publishes test elapsed time to the console, by default, but also available via the EngineExecutionListener for customised reporting

• ExpectedExceptionExtension: allows you to run a test method with an expected exception and (optionally) exception message, delegating responsibility for making the assertion to the extension

• RandomBeansExtension: allows you to inject random instances of classes into your tests, useful when you need a class instance to test with but you don’t care about its contents

• SystemPropertyExtension: allows you to set system properties before test execution and reverts these changes on test completion

• TemporaryFolderExtension: allows you to create temporary files and directories in your tests, any such files or directories created in your tests are removed for you when the tests complete

• TestNameExtension: makes the current test name available inside test methods

• WatcherExtension: logs test execution flow including entry, exit and elapsed time in milliseconds
