## Overview
To test deployment by docker-compose(Both standalone and cluster)

    2. Insert data
    3. Build index 
    4. Search
    5. Stop Milvus

    1. Deploy Milvus (Previous Release)
    2. Insert data

## Usage
Make sure you have installed `docker`,`docker-compose` and `pymilvus`!
For different version, you should modify the value of `latest_tag`, `latest_rc_tag` and `Release`. Password of root is needed for deleting volumes dir.

```bash
$ bash test.sh -m ${Mode} -t ${Task} -p ${Password}
# Mode, the mode of milvus deploy. standalone or cluster"
# Task, the task type of test. reinstall or upgrade
# Password, the password of root"
```

run all tasks
```bash
$ bash run.sh -p ${Password}
# Password, the password of root"
```

## Integrate deploy test into CI
Provides a way to periodically run docker-compose deployment tests through GitHub action：[deploy-test](https://github.com/milvus-io/milvus/blob/master/.github/workflows/deploy-test.yaml)

- [x] Parallel testing for four deployment scenarios
- [x] Upload logs to artifacts for further debug
- [x] Email notification for test failure
- [x] Support helm deployment tests
- [x] Cover more detail information in email notification
