6. 实现自动化测试

从零到壹构建基于fabric-sdk-node的项目开发实战之六

自动化测试

之前的方式，需要我们每次都要输入命令，这样操作的话比较麻烦，所以现在我们对其进行简化，没有必要每次都输入一长串的命令来执行，而是将命令写在指定的脚本文件中，以后直接执行该脚本文件即可，此方式大大简化了测试步骤，提高效率。

终端窗口 1

进入项目根目录：

$ cd $HOME/kevin-fabric-sdk-node

创建 runApp.sh 文件并编辑

$ vim runApp.sh

runApp.sh 脚本文件具体作用如下：

• 在本地计算机上启动通过配置指定的网络环境
• 安装 fabric-client 和 fabric-ca-client 节点模块
• 并在PORT 4000上启动应用程序

runApp.sh 文件完整内容如下：

#!/bin/bash

function dkcl(){
        CONTAINER_IDS=$(docker ps -aq)
	echo
        if [ -z "$CONTAINER_IDS" -o "$CONTAINER_IDS" = " " ]; then
                echo "========== No containers available for deletion =========="
        else
                docker rm -f $CONTAINER_IDS
        fi
	echo
}

function dkrm(){
        DOCKER_IMAGE_IDS=$(docker images | grep "dev\|none\|test-vp\|peer[0-9]-" | awk '{print $3}')
	echo
        if [ -z "$DOCKER_IMAGE_IDS" -o "$DOCKER_IMAGE_IDS" = " " ]; then
		echo "========== No images available for deletion ==========="
        else
                docker rmi -f $DOCKER_IMAGE_IDS
        fi
	echo
}

function restartNetwork() {
	echo

        #teardown the network and clean the containers and intermediate images
	cd artifacts
	docker-compose down
	dkcl
	dkrm

	#Cleanup the material
	rm -rf /tmp/hfc-test-kvs_peerOrg* $HOME/.hfc-key-store/ /tmp/fabric-client-kvs_peerOrg*

	#Start the network
	docker-compose up -d
	cd -
	echo
}

function installNodeModules() {
	echo
	if [ -d node_modules ]; then
		echo "============== node modules installed already ============="
	else
		echo "============== Installing node modules ============="
		npm install
	fi
	echo
}


restartNetwork

installNodeModules

PORT=4000 node app

添加可执行权限并执行 runApp.sh 脚本：

$ chmod 777 ./runApp.sh
$ ./runApp.sh

终端窗口 2

为了使 shell 脚本能够正确解析JSON，您必须安装 jq，详情请 参见此处

安装jq

$ sudo apt update
$ sudo apt install -y jq

进入项目根目录中：

$ cd $HOME/kevin-fabric-sdk-node

创建并编辑 testAPIs.sh 脚本文件

$ vim testAPIs.sh

testAPIs.sh 脚本文件的主要作用如下：

• 创建用户
• 创建通道
• 安装链码
• 实例化链码
• 调用链码
• 调用链码查询
• 执行其它查询

testAPIs.sh 文件完整内容如下：

#!/bin/bash
#
# Copyright IBM Corp. All Rights Reserved.
#
# SPDX-License-Identifier: Apache-2.0
#

jq --version > /dev/null 2>&1
if [ $? -ne 0 ]; then
	echo "Please Install 'jq' https://stedolan.github.io/jq/ to execute this script"
	echo
	exit 1
fi

starttime=$(date +%s)

# Print the usage message
function printHelp () {
  echo "Usage: "
  echo "  ./testAPIs.sh -l golang|node"
  echo "    -l  - chaincode language (defaults to \"golang\")"
}
# Language defaults to "golang"
LANGUAGE="golang"

# Parse commandline args
while getopts "h?l:" opt; do
  case "$opt" in
    h|\?)
      printHelp
      exit 0
    ;;
    l)  LANGUAGE=$OPTARG
    ;;
  esac
done

##set chaincode path
function setChaincodePath(){
	LANGUAGE=`echo "$LANGUAGE" | tr '[:upper:]' '[:lower:]'`
	case "$LANGUAGE" in
		"golang")
		CC_SRC_PATH="github.com/example_cc"
		;;
		"node")
		CC_SRC_PATH="$PWD/artifacts/src/github.com/example_cc/node"
		;;
		*) printf "\n ------ Language $LANGUAGE is not supported yet ------\n"$
		exit 1
	esac
}

echo "Total execution time : $(($(date +%s)-starttime)) secs ..."

应用程序在终端1中启动之后，接下来，我们通过执行 testAPIs.sh 脚本来测试API ：

添加可执行权限并执行 testAPIs.sh 脚本：

$ chmod 777 ./testAPIs.sh
$ ./testAPIs.sh

关闭并清理网络

创建清理网络的脚本文件：

$ cd $HOME/kevin-fabric-sdk-node
$ vim stopAPP.sh

文件中添加如下内容：

echo "shutdown fabric-network"
echo
docker-compose -f artifacts/docker-compose.yaml down
echo

echo "docker rm -f $(docker ps -aq)"
echo
docker rm -f $(docker ps -aq)
echo

echo "docker rmi -f $(docker images | grep dev | awk '{print $3}')"
echo
docker rmi -f $(docker images | grep dev | awk '{print $3}')
echo

echo "Delete current dir org-kv"
echo
rm -rf fabric-client-kv-org[1-2]
echo

echo "Delete tmp dir org-kv"
echo
rm -rf /tmp/fabric-client-kv-org[1-2]
echo

echo "shutdown and clear OK"

添加可执行权限并执行：

$ chmod 777 ./stopAPP.sh
$ ./stopAPP.sh
