JUnit 5 Test Templates for Eclipse

Eclipse has excellent tooling support for JUnit test cases. Having code templates for JUnit test cases configured in Eclipse is a perfect addition to faster test development.

Learn to create and import JUnit 5 test templates in Eclipse.

1. JUnit 5 Test Templates

Given below template file configure three JUnit 5 template methods i.e.

  1. setUp() annotated with @BeforeEach
  2. tearDown() annotated with @AfterEach
  3. testXXX() annotated with @Test

When we use test() template, it automatically adds this import statement:

import static org.junit.jupiter.api.Assertions.*;

It enables the use of all static assertXXX() methods directly into the test.

<?xml version="1.0" encoding="UTF-8" standalone="no"?><templates><template autoinsert="true" context="java" deleted="false" description="JUnit5 BeforeEach" enabled="true" name="setup (JUnit5)">${:import(org.junit.jupiter.api.BeforeEach)}
@BeforeEach
public void setUp() {
  ${cursor}
}</template><template autoinsert="true" context="java" deleted="false" description="JUnit5 AfterEach" enabled="true" name="teardown (JUnit5)">${:import(org.junit.jupiter.api.AfterEach)}
@AfterEach
public void tearDown() {
  ${cursor}
}</template><template autoinsert="false" context="java-members" deleted="false" description="JUnit5 test method" enabled="true" id="org.eclipse.jdt.ui.templates.test" name="test (JUnit5)">${:import(org.junit.jupiter.api.Test)}
@Test
public void test${name}() {
    ${staticImport:importStatic('org.junit.jupiter.api.Assertions.*')}
    ${cursor} 
}</template></templates>

Save this XML into a file in the preferred location. We will import this file in the next step.

2. Import Code Templates into Eclipse

  1. Eclipse: Window->Preferences
  2. Java->Editor->Templates
  3. Import…
  4. Choose file
  5. Verify for template names “setup (JUnit5)”, “teardown (JUnit5)” and “test (JUnit5)” specific to JUnit 5
