获取JUnit的执行结果

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<MethodInfo> list;
    Boolean result;

    public String getScript_name() {
        return script_name;
    }

    public void setScript_name(String script_name) {
        this.script_name = script_name;
    }

    public List<MethodInfo> getList() {
        return list;
    }

    public void setList(List<MethodInfo> 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<MethodInfo> 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
MyResultRecorder [script_name=test.JunitDemo2, list=[MethodInfo [method_name=test2, result=true, error_msg=null]], result=true]

 

这样就通过重写junit的监听，将junit的执行结果，存储到一个对象当中
