Editing JUnit (section)

==Previous versions of JUnit==
According to Martin Fowler, one of the early adopters of JUnit:<ref>{{Cite web |title=bliki: Xunit |url=https://martinfowler.com/bliki/Xunit.html |access-date=2022-03-07 |website=martinfowler.com}}</ref>

|text=JUnit was born on a flight from Zurich to the 1997 [[OOPSLA]] in Atlanta. Kent was flying with Erich Gamma, and what else were two geeks to do on a long flight but program? The first version of JUnit was built there, pair programmed, and done test first (a pleasing form of meta-circular geekery).}}

As a side effect of its wide use, previous versions of JUnit remain popular, with JUnit 4 having over 100,000 usages by other software components on the [[Apache Maven|Maven]] Central repository.<ref name="Maven Central">{{cite web | url=https://mvnrepository.com/artifact/junit/junit/usages | title=JUnit | website=mvnrepository.com | access-date=29 October 2021}}</ref>

In JUnit 4, the annotations for test execution callbacks were {{code|@BeforeClass}}, {{code|@Before}}, {{code|@After}}, and {{code|@AfterClass}}, as opposed to JUnit 5's {{code|@BeforeAll}}, {{code|@BeforeEach}}, {{code|@AfterEach}}, and {{code|@AfterAll}}.<ref name="JUnit 5 User Guide: Writing Tests"/>{{sfn|Gulati|Sharma|2017|loc=Chapter  §2 Understanding CoreJunit 5|p=37-40}}

In JUnit 3, test fixtures had to inherit from {{code|junit.framework.TestCase}}.<ref name="JUnitCookbook">{{cite web
