-# integration-testing
+# integration-testing
+
+This repository is just an example how to do integration testing in Golang with a real Database. For this repostiory case, I use MySQL and Redis.
+An explanation about this repository could be found in my Medium post [@imantumorang](https://medium.com/@imantumorang)
+
+
+## How To Run The Test
+
+Prerequisite:
+- Docker (docker-compose)
+- go 1.11+
+- Unix environment 
+
+Locally:
+
+```shell
+
+$ make integration-test
+# Will run the integration testing of this projects. Wait until finished.
+
+$ make clear
+# After finished, clear all the testing dependencies
+```
