JUnit 4 & 5 Annotations Every Developer Should Know

A summary of JUnit 4 & 5 annotations with examples

Source: https://www.wallpapersrc.com

Before writing this article, I only knew a few commonly used JUnit 4 annotations such as

@RunWith 
@Test
@Before
@After
@BeforeClass
@AfterClass

How many times did you have to comment out a test? To my surprise, there are annotations to do just that.

@Ignore("Reason for ignoring")
@Disabled("Reason for disabling")

Well, it turns out that there are a handful of other annotations, especially in JUnit 5 that could help write better and more efficient tests.

What to expect?

In this article, I will cover the following annotations with usage examples. The purpose of this article is to introduce you to the annotation, it will not go into greater details of each annotation.
