Maven：未执行任何测试

Question

I am abe to run my Junit runner for Cucumber using maven command line. My runner file is located in /src/java/test/Runners/ directory. Following is the command that I am using:

mvn surefire:test -Dtest=OneTest.java

Following is my Cucumber Test Runner

import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(
    plugin = {"summary","pretty","com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:", "json:target/cucumber-report/TestResult.json"},
    monochrome = false,
    features = "src/test/resources/features/SampleTestFeatures/SampleTest.feature",
    glue="Steps")
public class OneTest{
}

I am able to run the tests via command line but after the tests have passed, the build fails giving the following error:

1 Scenarios (1 passed)
6 Steps (6 passed)

I have tried different versions of surefire plugin but in vain. The test passes all the time even if I launch it directly from the Test Runner as well as via maven command but via maven the build is always marked as failed. If anyone could point me where this error is coming from, it'd be of great help.

UPDATE: I know the following is not a smart option but replacing the maven surefire plugin like the following fixed my issue without modifying any other dependecy in the pom

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <dependencies>
                    <dependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit47</artifactId>
                        <version>2.22.2</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <parallel>both</parallel>
                    <threadCount>4</threadCount>
                    <includes>
                        <include>**/*Test</include>
                    </includes>
                </configuration>
            </plugin>

It works for Junit Runner Classes but not for TestNG. My tests are now passed and the maven build succeeds as well. If anyone has more generic way of implementing the same for both TestNG and Junit Runner classes, would be absolutely brilliant.

Answer 1

I believe the reason you are seeing the error is due to the way you are passing the test argument.

As per the Maven Surefire's official documentation , you need to pass test class name. So change your command line argument to -Dtest=OneTest

Edit: Ignore the above answer.

After looking at your pom.xml, one thing is certain that some older version of cucumber-core dependencies were included and also testng dependencies were included. I excluded those dependencies and it's working fine now.

Also, one of the plugin (com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:) is not compatible with cucumber version > 4.2.0. See this blog . So I removed that plugin.

OneTest.java

package Runners;

import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import org.junit.runner.RunWith;


@RunWith(Cucumber.class)
@CucumberOptions(
        plugin = {"summary","pretty","json:target/cucumber-report/TestResult.json"},
        monochrome = false,
        features = "src/test/resources/features/test.feature",
        glue="Steps")
