OpenClover 正在解析 XML 输出。 Java

Question

所以我最近安装了 OpenClover 并想解析输出的 XML 文件。我的目标是获取覆盖信息并将该信息放在 Java class.

中

上面的想象正是我想做的。那就是在我的 class 计算器中我有一个方法 "sum" 我想知道 class 测试中存在的测试 testSum 覆盖了方法 "sum".

问题是查看 OpenClover 的 XML 输出时，我不确定如何建立此连接。

这里是 XML 输出：

      </package>
   </testproject>
</coverage>

那么根据 XML 数据，我如何判断哪个测试覆盖了哪个方法？

编辑：添加了 Test.java 和 Calculator.java

Calculator.java

public class Calculator {
    public int sum(int a, int b){
        if(a > b) {
            return a + a + b;
        }
        return a+b;
    }
    public int mulitpliy(int a , int b){
        return a*b;
    }
    public int division(int a, int b){
        int c = a+b;
        int d = a-b;
        int f = a*d;
        return a / b;
    }
}

Test.java

import static org.junit.Assert.assertEquals;
public class Test {
    Calculator calc = new Calculator();
    @org.junit.Test
    public void testSum(){

        assertEquals(10,calc.sum(5,5));
        assertEquals(25,calc.sum(10,5));
    }
    @org.junit.Test
    public void testMulti(){
        assertEquals(10,calc.mulitpliy(5,2));
    }
}

基于@Hades 回答的示例输出：

Method name    :: signature="sum(int,int) : int"
Covered line   :: 6 covered by: signature="testSum() : void"
UncoveredLines :: 0

不幸的是，OpenClover 不会在 XML 报告中打印每个测试的覆盖率信息。从 HTML 报告中提取此信息也不容易。

我建议看一下 SnapshotPrinter 实用程序，它打印文件信息和类:

https://openclover.org/doc/manual/latest/hacking--measuring-per-test-coverage-for-manual-tests.html

由于 OpenClover 是开源的，您可以扩展 SnapshotPrinter 以获取有关各个方法的信息，请参阅：

https://github.com/openclover/clover/blob/c3729a8251787ea550b45260270d5cb48cb8f0f9/clover-core/src/main/java/com/atlassian/clover/optimization/SnapshotPrinter.java

或者，您可以直接从 clover.db 数据库中读取此信息。请在这里查看我对类似问题的回答：
