Chapter 13. Testing the native executable

Test the application running in the native mode to test the functionality of the native executable. Use @NativeImageTest annotation to build the native executable and run test against the http endpoints.

Procedure

  1. Open the pom.xml file and verify that the native profile contains the following elements:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>${surefire-plugin.version}</version>
        <executions>
            <execution>
                <goals>
                    <goal>integration-test</goal>
                    <goal>verify</goal>
                </goals>
                <configuration>
                    <systemPropertyVariables>
                        <native.image.path>${project.build.directory}/${project.build.finalName}-runner</native.image.path>
                        <java.util.logging.manager>org.jboss.logmanager.LogManager</java.util.logging.manager>
                        <maven.home>${maven.home}</maven.home>
                    </systemPropertyVariables>
                </configuration>
            </execution>
        </executions>
    </plugin>

    The failsafe-maven-plugin runs integration test and indicates the location of the produced native executable.

  2. Open the src/test/java/org/acme/quickstart/NativeGreetingResourceIT.java file and verify that it includes the following content:

    package org.acme.quickstart;
    
    
    import io.quarkus.test.junit.NativeImageTest;
    
    @NativeImageTest 1
    public class NativeGreetingResourceIT extends GreetingResourceTest { 2
    
        // Run the same tests
    
    }
    1
    Use another test runner that starts the application from the native file before the tests. The executable is retrieved using the native.image.path system property configured in the Failsafe Maven Plugin.
    2
    This example extends the GreetingResourceTest, but you can also create a new test.
  3. Run the test:

    ./mvnw verify -Pnative

    The following example shows the output of this command:

    ./mvnw verify -Pnative

    Note

    Quarkus waits for 60 seconds for the native image to start before automatically failing the native tests. You can change this duration using the quarkus.test.native-image-wait-time system property.

    You can extend the wait time using the following command where <duration> is the wait time in seconds:

    ./mvnw verify -Pnative -Dquarkus.test.native-image-wait-time=<duration>
