java.lang.NullPointerException：无法调用“javax.script.ScriptEngine.createBindings()”，因为“com.intuit.karate.ScriptBindings.NASHORN”为空

Question

空手道专家您好，

我在尝试从 IntelliJ 执行空手道测试时看到以下错误。

*<ServiceName>*.ParallelRunner > testParallel FAILED
    java.lang.ExceptionInInitializerError
        at com.intuit.karate.Runner$Builder.tagSelector(Runner.java:80)

        Caused by:

我使用的空手道版本是 testImplementation 'com.intuit.karate:karate-junit4:0.9.6' 和 java 版本是 17。有人可以建议解决此错误的最佳方法吗？

以下命令通过了必要的凭据，用于执行测试

./gradlew clean acceptanceTest -Dkarate.clientId='<>' \                                                                                                                           ─╯
-Dkarate.clientSecret='<>' \
-Dkarate.abTestMgmt='<>' \
-Dkarate.env='<>' -Dkarate.options="--tags @CRUD_ConfigurationId" --info

下面是paralleRunner文件

package *<serviceName>*;

import com.intuit.karate.KarateOptions;
import com.intuit.karate.Results;
import com.intuit.karate.Runner;
import lombok.extern.slf4j.Slf4j;
import net.masterthought.cucumber.Configuration;
import net.masterthought.cucumber.ReportBuilder;
import org.apache.commons.io.FileUtils;
import org.junit.Test;

import java.io.File;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import static junit.framework.TestCase.assertTrue;

@Slf4j
@KarateOptions(tags = {"~@newFeature", "~@ignore", "~@50Test"})
public class ParallelRunner {

    @Test
    public void testParallel() {
        Results results = Runner.parallel(getClass(), 10);
        generateReport(results.getReportDir());
        assertTrue(results.getErrorMessages(), results.getFailCount() == 0);
    }

    public static void generateReport(String karateOutputPath) {
        Collection<File> jsonFiles = FileUtils.listFiles(new File(karateOutputPath), new String[]{"json"}, true);
        List<String> jsonPaths = new ArrayList<>(jsonFiles.size());
        jsonFiles.forEach(file -> jsonPaths.add(file.getAbsolutePath()));
        Configuration config = new Configuration(new File("target"), "*ServiceName*_AcceptanceTest");
        ReportBuilder reportBuilder = new ReportBuilder(jsonPaths, config);
        reportBuilder.generateReports();
    }

}

空手道版本的升级可能会有所帮助，但该项目使用 junit4 进行集成和单元测试。继续前进最好的事情是什么？

我尝试将空手道版本升级到最新版本，但由于使用了 junit 依赖项，在集成和单元测试中看到了很多错误。谢谢！！

删除 karate-apache 依赖项。所以你只剩下
karate-junit5 依赖于最新版本。这对我有用。
