Spock有测试事件监听器吗？

Question

spock是否有像TestNg一样的Test事件监听器ITestListener.？

因此,当测试用例失败时,我可以访问.

Answer 1

Spock确实有听众.不幸的是,官方文档,在其他方面非常出色,在编写自定义扩展下有"TODO" :http://spockframework.github.io/spock/docs/1.0/extensions.html.

更新:官方文档已更新,包含有关自定义扩展的有用信息:http://spockframework.org/spock/docs/1.1/extensions.html.有关更多详细信息,请参阅

有两种方法:基于注释和全局.

注释为主

这里有三个部分:注释,扩展和听众.

注释:

import java.lang.annotation.*
import org.spockframework.runtime.extension.ExtensionAnnotation

@Retention(RetentionPolicy.RUNTIME)
@Target([ElementType.TYPE, ElementType.METHOD])
@ExtensionAnnotation(ErrorListenerExtension)
@interface ListenForErrors {}

扩展(更新):

import org.spockframework.runtime.extension.AbstractAnnotationDrivenExtension
import org.spockframework.runtime.model.SpecInfo

class ListenForErrorsExtension extends AbstractAnnotationDrivenExtension<ListenForErrors> {
    void visitSpec(SpecInfo spec) {
        spec.addListener(new ListenForErrorsListener())
    }

   @Override
   void visitSpecAnnotation(ListenForErrors annotation, SpecInfo spec){
    println "do whatever you need here if you do. This method will throw an error unless you override it"
}
}

听众:

import org.spockframework.runtime.AbstractRunListener
import org.spockframework.runtime.model.ErrorInfo

class ListenForErrorsListener extends AbstractRunListener {
    void error(ErrorInfo error) {
        println "Test failed: ${error.method.name}"
        // Do other handling here
    }
}

然后,您可以在Spec类或方法上使用新注释:

@ListenForErrors
class MySpec extends Specification {
    ...
}

全球

这也有三个部分:扩展,监听器和注册.

class ListenForErrorsExtension implements IGlobalExtension {
    void visitSpec(SpecInfo specInfo) {
        specInfo.addListener(new ListenForErrorsListener())
    }
}

您可以使用与ListenForErrorsListener上面相同的类.

要注册扩展,请创建目录中指定org.spockframework.runtime.extension.IGlobalExtension的META-INF/services文件.如果使用Gradle/Maven,这将是src/test/resources.此文件应仅包含全局扩展的完全限定类名,例如:

com.example.tests.ListenForErrorsExtension

例如,请参阅Spock内置扩展:https : //github.com/spockframework/spock/tree/groovy-1.8/spock-core/src/main/java/spock/lang https://github.com /spockframework/spock/tree/groovy-1.8/spock-core/src/main/java/org/spockframework/runtime/extension/builtin

Answer 2

Spock 通过 Mock 进行交互监听：

def "should send messages to all subscribers"() {
    given:
    def subscriber = Mock(Subscriber)

    when:
    publisher.send("hello")

    then:
    1 * subscriber.receive("hello")
}

请参阅文档中基于交互的测试
