Eclemma说，4个分支中有1个没有被覆盖，但是哪个分支呢？ [英] Eclemma says 1 of 4 branches not covered, but which branch is it?

问题描述

有没有一个简单的方法来告诉我哪个分支机构缺少？即我有一些这样的代码：

  if（x || y）{
 // do stuff 
）
  

在覆盖范围突出显示中，Eclipse中有一个黄点，说：

4个分支中有1个错过了

但是我想知道哪个分支丢失。

解决方案

An 开放问题在Eclemma的父母的github回购中， jacoco 不过，即使没有Eclemma功能，如果目标只是为了弄清楚分支机构错过的分支机构，那么这个功能实际上有点难以包含在内。

一个具体的例子，你可以调整你的代码来跟踪。最简单的例子是老式的打印语句：

  if（x || y）{
 System.out.println （BRANCH：+ x +，+ y）; 
 //做东西
} 
  

然后看看输出，看看分支您实际打了（例如 java ... | grepBRANCH：| sort | uniq ）。 （不是很满意，我知道。）

Is there a simple way to tell which branch I am missing? I.e. I have some code like this:

if (x || y) {
    // do stuff
}

In the coverage highlighting there is a yellow dot in Eclipse that says:

1 of 4 branches missed

but I would like to know which branch is missing.

解决方案

An open issue on the github repo for Eclemma's parent, jacoco, suggests that such a feature would actually be a bit difficult to include.

However, even without an Eclemma feature, if the goal is just to figure out the branches missed in a specific case, you could instrument your code to keep track. The simplest example is old fashioned print statements:

if (x || y) {
    System.out.println("BRANCH: " + x + ", " + y);
    // Do stuff
}

Then look at the output and see what branches you actually hit (e.g. java ... | grep "BRANCH:" | sort | uniq). (not terribly satisfying, I know.)
