– Spring Tool Suite – Version 3.8.1.RELEASE
– Spring Boot: 1.5.6RELEASE

II. Skip Test with Maven & SpringBoot

1. Preparation

Firstly, using SpringToolSuite to create a SpringBoot project as below:

Then modify SpringMavenSkipTestApplicationTests class as below:

package com.javasampleapproach.maven.skiptest;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringMavenSkipTestApplicationTests {

	@Test
	public void contextLoads() {
		System.out.println("###############################################################");
		System.out.println("============================Testing============================");
		System.out.println("###############################################################");
	}

}

2. Skip Test

2.1 skipTests & maven.test.skip

We can control the testing when running Maven build through skipTests or maven.test.skip properties.

How to use? -> We use them via commandlines: mvn clean install -DskipTests or mvn clean install -Dmaven.test.skip=true

What is the difference between them?

– maven.test.skip property will skip compiling and skip running the tests. It is honored by Surefire, Failsafe and the Compiler Plugin.

– skipTests is the feature of Surefire. It will complile BUT NOT run the tests.

2.2 skipping by default

We set properties {skipTests, maven.test.skip} in the pom.xml file.

with maven.test.skip

  [...]
	
		...
		true
		...
	
  [...]

To enable test, we use commandline: mvn clean install -Dmaven.test.skip=false.

with skipTests

  [...]
  
    ...
    true
	...
  
  [...]
  
    
      
        org.apache.maven.plugins
        maven-surefire-plugin
        
          ${skipTests}
        
      
    
  
  [...]

To enable test, we use commandline: mvn clean install -DskipTests=false.

results

-> With commandline mvn clean install:

-> Enable tests by commandline mvn clean install -Dmaven.test.skip=false or mvn clean install -DskipTests=false:
