junit执行之后会有一个结果展示，下面就来看一下怎么获取这些结果并将其存储为一个对象

junit代码如下：

package test;import org.junit.After;import org.junit.Assert;import org.junit.Before;import org.junit.Test;public class JunitDemo {    @Before    public void bofore() {        System.out.println("bofore");    }    @After    public void after() {        System.out.println("after");    }    @Test    public void test1() {        System.out.println("test1");        Assert.assertEquals(1, 2);    }    @Test    public void test2() {        System.out.println("test2");        Assert.assertEquals(1, 1);    }    @Test    public void test3() {        System.out.println("test3");        Integer.valueOf("aede21");    }}

首先先写两个类，分别是结果对象和结果中的方法执行结果对象

结果记录类：

package test;import java.util.List;public class MyResultRecorder {    String script_name;    List
     
       list;    Boolean result;    public String getScript_name() {        return script_name;    }    public void setScript_name(String script_name) {        this.script_name = script_name;    }    public List
      
        getList() {        return list;    }    public void setList(List
       
         list) {        this.list = list;    }    public Boolean getResult() {        return result;    }    public void setResult(Boolean result) {        this.result = result;    }    @Override    public String toString() {        return "MyResultRecorder [script_name=" + script_name + ", list=" + list + ", result=" + result + "]";    }}

记录中的方法：

package test;public class MethodInfo {    String method_name;    Boolean result;    String error_msg;    public String getMethod_name() {        return method_name;    }    public void setMethod_name(String method_name) {        this.method_name = method_name;    }    public Boolean getResult() {        return result;    }    public void setResult(Boolean result) {        this.result = result;    }    public String getError_msg() {        return error_msg;    }    public void setError_msg(String error_msg) {        this.error_msg = error_msg;    }    @Override    public String toString() {        return "MethodInfo [method_name=" + method_name + ", result=" + result + ", error_msg=" + error_msg + "]";    }}

然后，需要写一个监听器ExecutionListener，继承junit的RunListener，并在监听时给对象赋值

package test;import java.util.ArrayList;import java.util.List;import org.junit.runner.Description;import org.junit.runner.Result;import org.junit.runner.notification.Failure;import org.junit.runner.notification.RunListener;public class ExecutionListener extends RunListener {    MyResultRecorder recorder;    MethodInfo methodInfo;    List
     
       list;    public ExecutionListener() {        this.list = new ArrayList<>();    }    public void testRunStarted(Description description) throws Exception {        System.out.println("--------- START ----------");        recorder = new MyResultRecorder();    }    public void testRunFinished(Result result) throws Exception {        recorder.setResult(result.wasSuccessful());        recorder.setList(list);        System.out.println("--------- END ----------");        System.out.println("执行结果 : " + result.wasSuccessful());        System.out.println("执行时间 : " + result.getRunTime());        System.out.println("执行数量 : " + result.getRunCount());        System.out.println("失败数量 : " + result.getFailureCount());        System.out.println("忽略数量 : " + result.getIgnoreCount());    }    public void testStarted(Description description) throws Exception {        recorder.setScript_name(description.getClassName());        System.out.println(description.getMethodName() + " begin");        methodInfo = new MethodInfo();        methodInfo.setMethod_name(description.getMethodName());    }    public void testFinished(Description description) throws Exception {        System.out.println(description.getMethodName() + " end");        if (methodInfo.getError_msg() == null)            methodInfo.setResult(true);        list.add(methodInfo);    }    public void testFailure(Failure failure) throws Exception {        System.out.println("Execution of test case failed : " + failure.getMessage());        methodInfo.setResult(false);        methodInfo.setError_msg(failure.getMessage());    }    public void testIgnored(Description description) throws Exception {    }}

写一个junit的类，做多个执行的处理

package test;import org.junit.After;import org.junit.Assert;import org.junit.Before;import org.junit.Test;public class JunitDemo2 {    @Before    public void bofore() {        System.out.println("bofore");    }    @After    public void after() {        System.out.println("after");    }    @Test    public void test2() {        System.out.println("test2");        Assert.assertEquals(1, 1);    }}

最后，写一个执行类，看一下执行的效果

package test;import org.junit.runner.JUnitCore;public class Execute {    public static void main(String[] args) {        run(JunitDemo.class, JunitDemo2.class);    }    private static void run(Class
     ... classes) {        for (Class
      clazz : classes) {            JUnitCore runner = new JUnitCore();            ExecutionListener listener = new ExecutionListener();            runner.addListener(listener);            runner.run(clazz);            MyResultRecorder recorder = listener.recorder;            System.out.println(recorder);        }    }}

执行的结果如下：

--------- START ----------

test1 begin

bofore

test1

after

Execution of test case failed : expected:<1> but was:<2>

test1 end

test2 begin

bofore

test2

after

test2 end

test3 begin

bofore

test3

after

Execution of test case failed : For input string: "aede21"

test3 end

--------- END ----------

执行结果 : false

执行时间 : 11

执行数量 : 3

失败数量 : 2

忽略数量 : 0

MyResultRecorder [script_name=test.JunitDemo, list=[MethodInfo [method_name=test1, result=false, error_msg=expected:<1> but was:<2>], MethodInfo [method_name=test2, result=true, error_msg=null], MethodInfo [method_name=test3, result=false, error_msg=For input string: "aede21"]], result=false]

--------- START ----------

test2 begin

bofore

test2

after

test2 end

--------- END ----------

执行结果 : true

执行时间 : 1

执行数量 : 1

失败数量 : 0

忽略数量 : 0
