goc

goc is a comprehensive coverage testing system for The Go Programming Language, especially for some complex scenarios，like system testing code coverage collection and accurate testing.

Note:

This readme and related documentation are Work in Progress.

Installation

To install goc tool, you need to install Go first (version 1.11+ is required), then:

go get -u github.com/qiniu/goc

Examples

You can use goc tool in many scenarios.

Code Coverage Collection for your Golang System Tests

Goc can collect code coverages at runtime for your long-run golang applications. To do that, normally just need three steps:

1. use goc server to start a service registry center:

   ➜  simple-go-server git:(master) ✗ goc server
   

2. use goc build to build the target service, and run the generated binary. Here let's take the simple-go-server project as example:

   ➜  simple-go-server git:(master) ✗ goc build .
   ... // omit logs
   ➜  simple-go-server git:(master) ✗ ./simple-go-server  
   

3. use goc profile to get the code coverage profile of the started simple server above:

   ➜  simple-go-server git:(master) ✗ goc profile
   mode: atomic
   enricofoltran/simple-go-server/main.go:30.13,48.33 13 1
   enricofoltran/simple-go-server/main.go:48.33,50.3 1 0
   enricofoltran/simple-go-server/main.go:52.2,65.12 5 1
   enricofoltran/simple-go-server/main.go:65.12,74.46 7 1
   enricofoltran/simple-go-server/main.go:74.46,76.4 1 0
   ...   
   

   Enjoy, Have Fun!

RoadMap

• Support code coverage collection for system testing.
• Support code coverage counters clear for the services under test at runtime.
• Support develop mode towards accurate testing.
• Support code coverage diff based on Pull Request.
• Optimize the performance costed by code coverage counters.
