Run Tests SpringBootTest from executable jar in command line

Question

I need to run a jar with all tests in it. I could build all test classes inside jar but I don't know how to boot a main class to run junit tests in springboot. Is it possible I run a command line to run jar and start all test and ignore mainclass.

Test Class

@ExtendWith(SpringExtension.class) @AutoConfigureMockMvc @SpringBootTest @TestPropertySource(locations = "classpath:${test.config.env:application-local.properties}") @TestMethodOrder(OrderAnnotation.class) public class RunIntegrationTest { // All tests }

Pom.xml

 <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.2.RELEASE</version> <relativePath /> </parent> <groupId>...</groupId> <artifactId>...</artifactId> <version>...</version> <name>...</name> <properties> <java.version>1.8</java.version> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <!-- get all compiled class tests into source class --> <testOutputDirectory>target/classes</testOutputDirectory> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

What do I need to exec for running all tests from built jar on command line?

 java -jar build-with-class-test-and-junit-in-it.jar # are there more parameters?

I've got a solution to run springboot test in jar using junit4 and SpringRunner.

Creating Test Class

import org.junit.FixMethodOrder; import org.junit.Test; // don't use org.junit.jupiter.api.test for this case import org.junit.runner.RunWith; import org.junit.runners.MethodSorters; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.TestPropertySource; import org.springframework.test.context.junit4.SpringRunner; import org.springframework.test.web.servlet.MockMvc; @RunWith(SpringRunner.class) // using SpringRunner instead of @ExtendWith(SpringExtension.class) @AutoConfigureMockMvc @SpringBootTest @TestPropertySource(locations = "classpath:application-${spring.profiles.active:local}.properties") @FixMethodOrder(MethodSorters.NAME_ASCENDING) public class RunIntegrationTest { @Autowired private MockMvc mockMvc; @Test // ... all integration test @Test // ... all integration test }

creating file pom-test-jar.xml

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.2.RELEASE</version> <relativePath /> </parent> <groupId>...</groupId> <artifactId>...</artifactId> <version>...</version> <name>...</name> <properties> <java.version>1.8</java.version> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <!-- all test class will be compiled with all source --> <!-- <scope>test</scope> --> </dependency> </dependencies> <build> <!-- all test class will be compiled with all source --> <testOutputDirectory>target/classes</testOutputDirectory> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <!-- changing launcher to exec junit instead of spring main class --> <mainClass>org.junit.runner.JUnitCore</mainClass> <includeSystemScope>true</includeSystemScope> </configuration> </plugin> </plugins> </build> </project>

That's all :)

Let's creating jar with test in it and run all test

# BUILD TEST JAR: mvn -f "pom-test-jar.xml" clean package -DskipTests # RUN TEST INTEGRATION export SPRING_PROFILES_ACTIVE=hom java -jar target/myjar.jar br.com.package.test.RunIntegrationTest unset SPRING_PROFILES_ACTIVE
