log形式

首先我们来看一段log输出:

info: Starting App

info: [debug] Attempting to kill all 'uiautomator' processes

info: [debug] Getting all processes with 'uiautomator'

info: [debug] executing cmd: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell "ps 'uiautomator'"

info: [debug] No matching processes found

info: [debug] Running bootstrap

info: [debug] spawning: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell uiautomator runtest AppiumBootstrap.jar -c io.appium.android.bootstrap.Bootstrap -e pkg com.example.android.apis -e disableAndroidWatchers false

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: numtests=1

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: stream=

info: [debug] [UIAUTOMATOR STDOUT] io.appium.android.bootstrap.Bootstrap:

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: test=testRunServer

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: class="io".appium.android.bootstrap.Bootstrap

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: current=1

info: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS_CODE: 1

info: [debug] [BOOTSTRAP] [debug] Socket opened on port 4724

info: [debug] [BOOTSTRAP] [debug] Appium Socket Server Ready

我将上面的log分为4种(message为消息体) 
1. log等级:message 
2. log等级:[debug] message 
3. log等级:[debug] [BOOTSTRAP] [debug] message 
4. log等级:[debug] [UIAUTOMATOR STDOUT] message

1.log等级:message

这一类log就是简单的appium服务器的log,切log等级为非debug

2.log等级:[debug] message

这一类log和上面是一样的,都是appium服务器的log,区别在于该log等级为debug,在logger.js模块中我们可以看到如下代码,下面的代码将debug等级的log,更改为info等级,然后在后面跟上[debug]的标志。

if (levels[logger.transports.console.level] === levels.debug) {

logger.debug = function (msg) { logger.info('[debug] ' + msg); };

}

3.[debug] [BOOTSTRAP] [debug] message

这一类log为手机中的socket服务器包(放在android手机端的jar包称为bootstrap)返回的输出

4.log等级:[debug] [UIAUTOMATOR STDOUT] message

这一类log为执行case输出的log,我们可以理解为adb接受的log。我们一般执行uiautomator的case时候,控制台输出的就是这类带有uiautomator标识的log。

自定义log部分

log等级

第一步我们来修改log等级。比如我们想将info级别改为warn级别,只需要将logger.js的223行左右的如下代码

if (levels[logger.transports.console.level] === levels.debug) {

logger.debug = function (msg) { logger.info('[debug] ' + msg); };

}

修改为

这里就将debug等级的修改为了warn模式的,info模式还是info模式(我之前说过,你应该知道为什么改变的是debug而不是info等级吧?)。我们来看看输出:

info: Starting App

warn: [debug] Attempting to kill all 'uiautomator' processes

warn: [debug] Getting all processes with 'uiautomator'

warn: [debug] executing cmd: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell "ps 'uiautomator'"

warn: [debug] No matching processes found

warn: [debug] Running bootstrap

warn: [debug] spawning: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell uiautomator runtest AppiumBootstrap.jar -c io.appium.android.bootstrap.Bootstrap -e pkg com.example.android.apis -e disableAndroidWatchers false

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: numtests=1

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: stream=

warn: [debug] [UIAUTOMATOR STDOUT] io.appium.android.bootstrap.Bootstrap:

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: test=testRunServer

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: class="io".appium.android.bootstrap.Bootstrap

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: current=1

warn: [debug] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS_CODE: 1

warn: [debug] [BOOTSTRAP] [debug] Socket opened on port 4724

warn: [debug] [BOOTSTRAP] [debug] Appium Socket Server Ready

我们将info改变成了warn,但是还是存在info标志的,因为上面代码的改变是建立在你调用的logger.debug,因为我们之前说过了,appium会将debug等级改为info,然后在后面加一个[debug]标志,现在我们改为warn,那么之前debug会改为warn,然后加一个[debug]标志。所以凡是warn后面必然会跟一个[debug]。

debug标识

上面的debug,会在info/warn/error标识后面加一个[debug],是不是很丑,我是觉得很丑,我们将其改变一下改成[TesterHome],还是刚才的代码:

手机自动化测试:Appium代码之Logger

info: Starting App

warn: [TesterHome] Attempting to kill all 'uiautomator' processes

warn: [TesterHome] Getting all processes with 'uiautomator'

warn: [TesterHome] executing cmd: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell "ps 'uiautomator'"

warn: [TesterHome] No matching processes found

warn: [TesterHome] Running bootstrap

warn: [TesterHome] spawning: /Users/wuxian/Documents/tools/sdk/platform-tools/adb -s emulator-5554 shell uiautomator runtest AppiumBootstrap.jar -c io.appium.android.bootstrap.Bootstrap -e pkg com.example.android.apis -e disableAndroidWatchers false

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: numtests=1

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: stream=

warn: [TesterHome] [UIAUTOMATOR STDOUT] io.appium.android.bootstrap.Bootstrap:

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: test=testRunServer

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: class="io".appium.android.bootstrap.Bootstrap

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS: current=1

warn: [TesterHome] [UIAUTOMATOR STDOUT] INSTRUMENTATION_STATUS_CODE: 1

warn: [TesterHome] [BOOTSTRAP] [debug] Socket opened on port 4724

warn: [TesterHome] [BOOTSTRAP] [debug] Appium Socket Server Ready

ok了。

觉得UIAUTOMATOR STDOUT和BOOTSTRAP不理解?

没关系,写成中文,在devices/android/uiautomator.js文件中,找到190和203行左右的语句,将上面两个标识符修改为中文: 
修改前:

修改后:

输出为:
