【Cucumber系列】使用Google Guice 框架

目录

Gradle依赖

新建Feature文件

新建Step文件

新建Interface

实现Interface

新建Module binding

新建目录

新建cucumber.properties文件

直接执行Fearute文件输出如下：

Gradle依赖

    testImplementation 'io.cucumber:cucumber-java8:7.2.3'
    testImplementation 'io.cucumber:cucumber-junit:7.2.3'
    implementation 'io.cucumber:cucumber-guice:7.2.3'
    implementation 'com.google.inject:guice:5.1.0'

新建Feature文件

@test
Feature: Two number addition

  Scenario: Verify two number addition
    Given two number addition and verify

新建Step文件

import com.appautomation.learn.learnguice.TwoNumAddition;
import com.google.inject.Inject;
import io.cucumber.java8.En;
import org.junit.Assert;

public class TwoNumAddSteps implements En{
    @Inject
    public TwoNumAddSteps(TwoNumAddition twoNumAddition) {
        Given("^two number addition and verify$", () -> {
            int a = 10;
            int b = 20;
            int expectedResult = a + b;
            int actualResult = twoNumAddition.twoNumAdd(a, b);
            Assert.assertEquals(expectedResult, actualResult);
        });
    }
}

新建Interface

public interface TwoNumAddition {
    int twoNumAdd(int a, int b);
}

实现Interface

public class TwoNumAdditionImpl implements TwoNumAddition{
    @Override
    public int twoNumAdd(int a, int b) {
        return a + b;
    }
}

新建Module binding

import com.google.inject.AbstractModule;

public class TestModule extends AbstractModule {
    @Override
    protected void configure() {
        //将Interface绑定到具体的实现类
        bind(TwoNumAddition.class).to(TwoNumAdditionImpl.class);
    }
}

 实现CustomObjectFactory 类

import com.appautomation.learn.learnguice.TestModule;
import com.google.inject.Guice;
import com.google.inject.Injector;
import com.google.inject.Stage;
import io.cucumber.core.backend.ObjectFactory;
import io.cucumber.guice.CucumberModules;
import io.cucumber.guice.ScenarioScope;

public final class CustomObjectFactory implements ObjectFactory {

    private final Injector injector;

    public CustomObjectFactory() {
        // Create an injector with our service module
        this.injector =
                Guice.createInjector(
                        Stage.PRODUCTION,
                        CucumberModules.createScenarioModule(),
                        new TestModule());
    }

    @Override
    public boolean addClass( Class< ? > clazz ) {
        return true;
    }

    @Override
    public void start() {
        this.injector.getInstance( ScenarioScope.class ).enterScope();
    }

    @Override
    public void stop() {
        this.injector.getInstance( ScenarioScope.class ).exitScope();
    }

    @Override
    public < T > T getInstance( Class< T > clazz ) {
        return this.injector.getInstance( clazz );
    }
}

新建ObjectFactory

新建src/test/resources/META-INF/services，该目录下新增文件io.cucumber.core.backend.ObjectFactory，文件内容为：

com.app.automation.conf.CustomObjectFactory

新建cucumber.properties文件

cucumber.object-factory=com.app.automation.conf.CustomObjectFactory

直接执行Fearute文件输出如下：
