Useful code templates

I’m using Eclipse in my everyday work and it has really useful feature of code template (it is available in Window -> Preferences -> Java -> Editor -> Templates). Below you can see templates which I’m using most often while writing test cases. I’m using JUnit4 and Mockito.

  • RunWith annotation with MockitoJUnitRunner 
    ${imp:import(org.mockito.runners.MockitoJUnitRunner)}
@${testType:newType(org.junit.runner.RunWith)}(MockitoJUnitRunner.class)

    Output:

    import org.junit.runner.RunWith;
import org.mockito.runners.MockitoJUnitRunner;

@RunWith(MockitoJUnitRunner.class)
  • Logger 
    ${:import(org.slf4j.Logger,org.slf4j.LoggerFactory)}
private static final Logger log = LoggerFactory.getLogger(${enclosing_type}.class);

    Output:

    private static final Logger log = LoggerFactory.getLogger(type.class);
  • Test case with useful imports and with given/when/then sections 
    ${staticImport:importStatic('org.junit.Assert.*','org.mockito.Mockito.*','org.hamcrest.Matchers.*','org.mockito.BDDMockito.*')}
@${testType:newType(org.junit.Test)}
public void should${testName}()
{
	// given
	${cursor}

	// when

	// then

}

    Output:

    import static org.hamcrest.Matchers.*;
import static org.junit.Assert.*;
import static org.mockito.BDDMockito.*;
import static org.mockito.Mockito.*;

@Test
public void shouldtestName()
{
	// given

	// when

	// then

}
  • Mock for specific type of object 
    ${type} ${name} = ${:importStatic(org.mockito.Mockito.mock)}mock(${type}.class);

    Output:

    type name = mock(type.class);
