JUnit @Disabled Example

By Arvind Rai, May 03, 2021
On this page we will learn using JUnit @Disabled annotation.
1. JUnit @Disabled annotation is introduced in JUnit 5. The @Disabled annotation is JUnit Jupiter API.
2. The @Disabled annotation is used to disable test methods. A disabled test method will not execute in unit test run.
3. The @Disabled annotation can be used at method level as well as class level.
4. When @Disabled is used at class level, all the test methods are disabled and they are not executed.
5. When @Disabled annotation is used at method level, then that method will not execute in test run. For @Disabled methods, their lifecycle callbacks such as @BeforeEach method and @AfterEach method will also not execute.
6. In a test class, if some test methods are annotated with @Disabled annotation then these test methods will not execute but other test methods will execute normally.
7. The @Disabled annotation optionally accepts a string data i.e. the description for disabling the test to execute.
@Disabled("Disabled until bug #123 is fixed.")
@Test
void additionTest() {
  ------
} 
8. The @Disabled annotation helps in documenting and reporting for disabled tests.


@Disabled at Method Level

Here we will disable a test method using @Disabled annotation. We just have to annotate the test method with @Disabled. We can optionally pass the reason for disabling this method to this annotation.
MyAppTest1.java
public class MyAppTest1 {
  @BeforeEach
  void init(TestInfo testInfo) {
	System.out.println("Start..." + testInfo.getDisplayName());
  }
  @Disabled("Disabled until bug #123 is fixed.")
  @Test
  void additionTest() {
	int sum = 50 + 60;
	assertEquals(110, sum);
  }
  @Test
  void multiplyTest() {
	int multi = 15 * 5;
	assertEquals(75, multi);
  }  
  @AfterEach
  void tearDown(TestInfo testInfo) {
	System.out.println("Finished..." + testInfo.getDisplayName());
  }
} 
Find the console output.
Start...multiplyTest()
Finished...multiplyTest()
In above unit test class, additionTest() will not execute. The @BeforeEach and @AfterEach methods for additionTest() will also not execute.
The multiplyTest method will execute normally with @BeforeEach and @AfterEach methods.

@Disabled at Class Level

Here we will use @Disabled annotation at class level. Once a class is annotated with @Disabled annotation, all the test methods of that class are disabled.
MyAppTest2.java
@Disabled("Disabled until change in User functionality is completed.")
public class MyAppTest2 {
  @BeforeEach
  void init(TestInfo testInfo) {
	System.out.println("Start..." + testInfo.getDisplayName());
  }
  @Test
  void additionTest() {
	int sum = 60 + 40;
	assertEquals(100, sum);
  }
  @Test
  void multiplyTest() {
	int multi = 20 * 5;
	assertEquals(100, multi);
  }  
  @AfterEach
  void tearDown(TestInfo testInfo) {
	System.out.println("Finished..." + testInfo.getDisplayName());
  }
} 

Find the print screen of the output.
