配置jest.config.js后，自动化测试依然无法使用android自定义基座进行测试

解决办法一：
直接不修改jest.config.js了，转而修改env.js的is-custom-runtime字段和app-plus.android.executablePath字段，
is-custom-runtime字段值为true，app-plus.android.executablePath字段值为自定义基座路径

module.exports = {  
    "is-custom-runtime": true,  
    "compile": true,  
    "h5": {  
        "options": {  
            "headless": true  
        },  
        "executablePath": ""  
    },  
    "mp-weixin": {  
        "port": 9420,  
        "account": "",  
        "args": "",  
        "cwd": "",  
        "launch": true,  
        "teardown": "disconnect",  
        "remote": false,  
        "executablePath": ""  
    },  
    "app-plus": {  
        "android": {  
            "id": "192.168.10.5",  
            "executablePath": "E:\\book\\unpackage\\debug\\android_debug.apk"  
        },  
        "version": "E:\\HBuilderX\\HBuilderX\\plugins\\launcher\\base\\version.txt",  
        "ios": {  
            "id": "",  
            "executablePath": ""  
        }  
    }  
}
