在角度2的单元测试中询问“覆盖范围摘要"吗? [英] Asking about the Coverage summary in Unit test of angular 2?

问题描述

当我在角度2中运行测试时，在覆盖率摘要"部分的控制台命令上看到一些关键字输出为Statements，Branches，Functions....

When I run test in angular 2 and I see a few keywords output on console command in Coverage Summary section as Statements, Branches, Functions....

我不知道到底是什么吗?

And I don't know exactly what is it?

任何帮助帮我解释一下，谢谢.

Any help explain this for me, thank you.

推荐答案

• 声明:我认为这篇文章做了很好的工作，解释了它的陈述.覆盖范围测试您的所有语句都被击中.

  • Statement: I think this article does a pretty goo d job explaining what a statement it. The coverage tests that all your statements are getting hit.

    分支:使用条件词时会创建分支

    Branch: When you use conditionals it create branches

    if (condition) {
      doThis();       // this is a branch
    } else {
      doThat();       // this is a branch
    }
    

    您的测试是否遍及所有分支机构?

    Is your testing hitting all the branches?

    功能:您声明的功能.

    class SomeClas {
      methodOne() {}
      methodTwo() {}
    }
    
    it('..', () => {
      new SomeClass().methodOne();
    })
    

    SomeClass有两种方法，但是只有一种正在接受测试. 50％.如果您在测试中明确呼叫methodTwo或 methodOne呼叫methodTwo，则覆盖率达到100％

    SomeClass has two methods, but only one is getting tested. 50%. If you either explicitly call methodTwo in your test or methodOne calls methodTwo, your coverage goes to 100%

    行::代码行，检查是否所有代码行都被命中.

    Lines:: The lines of code, checks to see if all the lines of code are being hit.
