Spock框架：间谍问题

问题描述

我在Spock中使用Spy存在一个问题，它要么不能正常工作，要么我的理解错误，所以我试图澄清这一点。
考虑这个代码（Java）：

pre code public class CallingClass {

public String functionOne （）{
//做东西
返回one;


public String functionTwo（）{
String one = functionOne（）;
返回一些字符串+一个;






$ b现在我想测试中设置断点， code>它会被调用：（$ / b>

我缺少什么？不应该使用存根 functionOne 提供并返回字符串mocked function return？

解决方案

$ $ p $ code $ @Grab（'org.spockframework：spock-core：0.7-groovy-2.0'）
@Grab（'cglib：cglib-nodep：3.1'）

import spock.lang。*

class CallingClassTest extends Specification {

def检查functionTwo调用functionOne（）{
def c = Spy（CallingClass）

当：
def s = c.functionTwo（）

then：
1 * c.functionOne（）>>mocked functi返回
s ==一些字符串模拟函数返回
}
}

public class CallingClass {

public String functionOne ）{
one
}

public String functionTwo（）{
String one = functionOne（）
some string $ one


$ / code>

当你们间谍/模拟并验证这是如何返回值应该被指定。

I have an issue with using Spy in Spock, it either doesn't work as it should or my understanding is wrong so I'm trying to clarify this.Consider this code (Java):

public class CallingClass {

    public String functionOne() {
        //does stuff
        return "one";
    }

    public String functionTwo() {
        String one = functionOne();
        return "some string " + one;
    }
}

Now I want to test the fact that functionTwo calls functionOne as well as define the returned value from functionOne (imagine for instance if functionOne is really complicated and I don't want to execute it in my test just want to stub it and set it to return a certain value). For this i write the following test in Groovy (using Spock):

class CallingClassTest extends Specification {

    def "check that functionTwo calls functionOne"() {
        def c = Spy(CallingClass)
        c.functionOne() >> "mocked function return"

        when:
        def s = c.functionTwo()

        then:
        1 * c.functionOne()
        s == "some string mocked function return"
    }
}

In order to do things like this, Spock is asking me to have the cglib library, so my build file (in Gradle) looks something like this:

apply plugin: 'groovy'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.codehaus.groovy:groovy:latest.release'

    testCompile 'org.spockframework:spock-core:latest.release'
    testCompile 'junit:junit:latest.release'
    testCompile 'cglib:cglib-nodep:latest.release'

}

Now when I run the test, I expect the functionOne not to be called at all, and instead my stubbed out version to be used. Instead, I get this:

Condition not satisfied:

s == "some string mocked function return"
| |
| false
| 19 differences (44% similarity)
| some string (-)o(-------)n(-------)e(----)
| some string (m)o(cked fu)n(ction r)e(turn)
some string one

Condition not satisfied:

s == "some string mocked function return"
| |
| false
| 19 differences (44% similarity)
| some string (-)o(-------)n(-------)e(----)
| some string (m)o(cked fu)n(ction r)e(turn)
some string one

    at CallingClassTest.check that functionTwo calls functionOne(CallingClassTest.groovy:17)

Even more so, if I debug this and set a breakpoint in functionOne it gets called :(

What am I missing? Shouldn't my test use the stubbed functionOne provided and just return the string "mocked function return"?

解决方案

It should be:

@Grab('org.spockframework:spock-core:0.7-groovy-2.0')
@Grab('cglib:cglib-nodep:3.1')

import spock.lang.*

class CallingClassTest extends Specification {

    def "check that functionTwo calls functionOne"() {
        def c = Spy(CallingClass)

        when:
        def s = c.functionTwo()

        then:
        1 * c.functionOne() >> "mocked function return"
        s == "some string mocked function return"
    }
}

public class CallingClass {

    public String functionOne() {
        "one"
    }

    public String functionTwo() {
        String one = functionOne()        
        "some string $one"
    }
}

When you both spy/mock and verify this is how return value should be specified.
