如何从 java TestRunner Class 运行 黄瓜测试

Question

与cucumber-groovy-example

合作

结果：

BUILD SUCCESSFUL

Total time: 19.643 secs

This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.7/userguide/gradle_daemon.html

如何从 Java 文件中 运行 进行相同的测试：例如

src/main/java/calc/TestRunner.java

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
import org.junit.runner.notification.Failure;

@RunWith(Cucumber.class)
@CucumberOptions(format = {"pretty"}, monochrome=true)

public class TestRunner {

                public static void main(String[] args) {
                                     System.out.println("dummy main java");
// I want to run the tests from within the jar file

                                          }
}

所以当我做 java -jar build/distributions/cucumber-jvm-groovy-example.jar

我应该得到与我通过命令行 gradle 到 运行 测试相同的结果

我使用了以下 Java Class:

import org.junit.*;
import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
import java.util.ArrayList;
import java.util.List;
import org.junit.runner.notification.Failure;

@RunWith(Cucumber.class)
@CucumberOptions(format = {"pretty"}, monochrome=true)

public class TestRunner {

        public static void main(String[] args) {
             System.out.println("dummy main java");
        JUnitCore.main("cucumberTest.TestRunner");
    }
}

但遇到异常：

  initializationError(org.junit.runner.JUnitCommandLineParseResult)
java.lang.IllegalArgumentException: Could not find class [cucumberTest.TestRunner]
        at org.junit.runner.JUnitCommandLineParseResult.parseParameters(JUnitCommandLineParseResult.java:102)
        at org.junit.runner.JUnitCommandLineParseResult.parseArgs(JUnitCommandLineParseResult.java:50)
        at org.junit.runner.JUnitCommandLineParseResult.parse(JUnitCommandLineParseResult.java:44)
        at org.junit.runner.JUnitCore.runMain(JUnitCore.java:72)
        at org.junit.runner.JUnitCore.main(JUnitCore.java:36)
        at TestRunner.main(TestRunner.java:19)
Caused by: java.lang.ClassNotFoundException: cucumberTest.TestRunner

这让我认为 JUnitCore.main() 需要一个 class 名称作为参数

Answer 1

一种方法是使用 command line runner. Java class Runtime 允许您从 Java 中执行命令行。关键是cucumber.api.cli.Main.

类似于this:

task cucumber() {
dependsOn assemble, compileTestJava
doLast {
    javaexec {
        main = "cucumber.api.cli.Main"
        classpath = configurations.cucumberRuntime + sourceSets.main.output + sourceSets.test.output
        args = ['--plugin', 'pretty', '--glue', 'gradle.cucumber', 'src/test/resources']
        }
    }
}

Answer 2

其他方法可以是创建任务并包含 运行ner class 用于测试

build.gradle-
task RunCukesTest(type: Test) << {
include "RunCukesTest.class"
}

your class - 
@RunWith(Cucumber.class)
@CucumberOptions(dryRun = false, strict = true, features = "src/test/resources", glue 
= "com.gradle.featuretests",monochrome = true)
public class RunCukesTest {
}

然后只需 运行 以下命令：-

gradle RunCukesTest
