有没有提供增量覆盖率的功能呀？ about goc

[CarlJi]

@gujing032 是否可以再具体描述下你这里的"增量"？

我理解的增量场景大概率是 - 作为研发，我提了一个PR/MR, 我只关心我这个PR的里面的代码覆盖率变化情况。而这个场景其实有些考量:

1. 代码放在哪里？github or gitlab？
2. 基准覆盖率结果如何获得？

所以这是个强环境相关的场景。目前goc落地了在Github里基于Prow的增量覆盖率场景，如果大家也使用Prow，可以尝试下: https://github.com/qiniu/goc/blob/master/cmd/diff.go#L51

No further questions, closing it now.

in my view, the increment/change/delta is not for previous coverage but code, which means we only aim at how many new codes we have covered in a new branch.
(I think the manager tends to regard more about the former, but as a QA, I the later)

by my mean, I use git diff to get code changes, then joint profile to filter what has been covered in our test, so that QA can add more cases for the uncovered codes in new branch.

Sure, the kind of scenario you're talking about seems make sense. and i think combining use git diff and goc profile is enough here. no need to use goc diff. @uveege

By the way，i am reopening this issue in order to let more users seeing these discussion easily.

能不能提供一个实际的例子来介绍如何使用goc做增量代码的覆盖？
