Raf*_*UBI 6 testing groovy maven spock maven-surefire-plugin
我正在使用Spock框架进行测试(1.0-groovy-2.4发布).Junit提供此选项以使用命令行(使用Maven)运行特定测试:
mvn -Dtest=TestCircle#mytest test
问题:我怎么能用Spock做到这一点？
这个版本依赖于Junit 4.12,在Junit文档中声明这个功能仅支持Junit 4.x,基本上Spock应该提出类似的东西.
经过进一步调查后,答案很可能是:不,你不能使用Surefire插件功能调用Spock的特定测试方法.下面的原因.
鉴于以下Spock测试用例:
import spock.lang.Specification
class HelloSpec extends Specification {
def hello = new Main();
def sayHello() {
given: "A person's name is given as a method parameter."
def greeting = hello.sayHello("Petri");
expect: "Should say hello to the person whose name is given as a method parameter"
greeting == "Hello Petri";
println "hello from HelloSpec"
}
}
并给出以下插件配置:
<plugin>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<goals>
<goal>addTestSources</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
<configuration>
<sources>
<fileset>
<directory>${pom.basedir}/src/test/java</directory>
<includes>
<include>**/*.groovy</include>
</includes>
</fileset>
</sources>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<includes>
<include>**/*Test.java</include>
<include>**/*Spec.java</include>
</includes>
</configuration>
</plugin>
它作为Maven test阶段执行的一部分运行良好mvn clean test:

Running com.sample.HelloSpec
hello from HelloSpec
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.314 sec - in com.sample.HelloSpec
即使执行mvn clean test -Dtest=HelloSpec你也能得到与上面完全相同的结果,成功执行.
那么,为什么我们不能运行单一方法呢？
如果我们javap在上面的HelloSpec示例测试中执行命令,我们得到以下输出:
Compiled from "HelloSpec.groovy"
public class com.sample.HelloSpec extends spock.lang.Specification implements groovy.lang.GroovyObject {
public static transient boolean __$stMC;
public com.sample.HelloSpec();
public void $spock_feature_0_0();
protected groovy.lang.MetaClass $getStaticMetaClass();
public groovy.lang.MetaClass getMetaClass();
public void setMetaClass(groovy.lang.MetaClass);
public java.lang.Object invokeMethod(java.lang.String, java.lang.Object);
public java.lang.Object getProperty(java.lang.String);
public void setProperty(java.lang.String, java.lang.Object);
public java.lang.Object getHello();
public void setHello(java.lang.Object);
}
因此在生成的字节码中没有sayHello方法,因为Spock更改方法名称以便在其中允许空格.因此,您编写的方法名称实际上并不是作为编译类的一部分的真实方法名称.
在这种情况下,方法名称很可能$spock_feature_0_0,而不是非常友好的东西.
这个答案以及Spock的作者Peter Niederwieser的评论也证实了这一点,所以这不仅仅是可靠的来源.
您可以尝试运行以下内容:
mvn clean test -Dtest=HelloSpec#*spock*
它应该确实匹配真正的方法名称,但你会收到一个错误

这很可能是因为使用直接调用名称,我们绕过了JUnit和Spock之间的粘合剂,因此执行失败.

我用:
Windows: mvn -Dtest="TestCircle#my test" test
*Nix: mvn "-Dtest=TestCircle#my test" test
它与surefire 2.19.1和junit 4.8.1完美配合.以下是代码示例和执行输出:
import spock.lang.Specification
class HelloSpec extends Specification {
def sayHello() {
given: "A person's name is given as a method parameter."
def greeting = "Hello Petri";
expect: "Should say hello to the person whose name is given as a method parameter"
greeting == "Hello Petri";
println "hello from HelloSpec"
}
def sayHi() {
expect:
1==1
println "sayHi from HelloSpec"
}
def "say hi to spock" () {
expect:
true
println "say hi to spock from HelloSpec"
}
}
#mvn test"-Dtest = HelloSpec#say hi to spock"
