# AndroidTestByPython
2-
Android使用Python进行自动化测试
2+
Android APP使用Python进行性能测试
3+
4+
### APP启动时间
5+
6+
#### 冷启动
7+
8+
- 启动APP命令
9+
10+
```shell
11+
adb shell am start -W -n package/activity
12+
```
13+
14+
- 停止App命令
15+
16+
```shell
17+
adb shell am force-stop package
18+
```
19+
20+
- 获取某个APP的packageName和ActivityName的命令
21+
22+
```shell
23+
adb logcat | grep START
24+
```
25+
26+
然后打开你想获取packageName和ActivityName的应用即可。
27+
28+
#### 热启动
29+
30+
- 启动APP命令和冷启动一样
31+
32+
- 停止App命令
33+
34+
```shell
35+
// 模拟点击back键
36+
adb shell input keyevent 3
37+
```
38+
39+
40+
41+
#### 自动化脚本的实现
42+
43+
两种方案：
44+
45+
- 获取命令执行时间，作为启动时间参考值
46+
47+
```python
48+
class App(object):
49+
def __init__(self):
50+
self.content = ""
51+
self.startTime = 0
52+
53+
# 启动APP
54+
def launch_app(self):
55+
cmd = 'adb shell am start -W -n org.chromium.webview_shell/.WebViewBrowserActivity' # type: str
56+
self.content = os.popen(cmd)
57+
58+
# 停止app
59+
@staticmethod
60+
def stop_app():
61+
# 冷启动停止的命令
62+
# cmd = 'adb shell am force-stop org.chromium.webview_shell'
63+
# 热启动停止的命令
64+
cmd = 'adb shell input keyevent 3'
65+
os.popen(cmd)
66+
67+
# 获取启动时间
68+
def get_launched_time(self):
69+
for line in self.content.readlines():
70+
if "ThisTime" in line:
71+
self.startTime = line.split(":")[1]
72+
break
73+
return self.startTime
74+
75+
# 单次测试过程
76+
def test_process(self):
77+
self.app.launch_app()
78+
time.sleep(5)
79+
elapsed_time = self.app.get_launched_time()
80+
self.app.stop_app()
81+
time.sleep(3)
82+
current_time = self.get_current_time()
83+
self.all_data.append((current_time, elapsed_time))
84+
85+
# 多次执行测试过程
86+
def run(self):
87+
while self.counter > 0:
88+
self.test_process()
89+
self.counter = self.counter - 1
90+
```
91+
92+
93+
94+
- 在命令前后加上时间戳，以差值作为参考值
95+
96+
```python
97+
# 单次测试过程
98+
def test_process(self):
99+
time_before_launch = int(time.time())
100+
self.app.launch_app()
101+
time_after_launch = int(time.time())
102+
time.sleep(5)
103+
# elapsed_time = self.app.get_launched_time()
104+
elapsed_time = time_after_launch - time_before_launch
105+
self.app.stop_app()
106+
time.sleep(3)
107+
current_time = self.get_current_time()
108+
self.all_data.append((current_time, str(elapsed_time)))
109+
110+
# 多次执行测试过程
111+
def run(self):
112+
while self.counter > 0:
113+
self.test_process()
114+
self.counter = self.counter - 1
115+
```
116+
117+
> 可以多次计算启动时间值，并保存到本地csv文件，进行统计分析，求平均值等，第一次获得的值最好弃用。
118+
119+
### APP的CPU占用情况
120+
121+
#### 获取数据
122+
123+
##### 命令
124+
125+
```shell
126+
# windows系统的cmd中，用findstr来过滤字符，不能用grep。
127+
adb shell dumpsys cpuinfo | grep packagename
128+
```
129+
130+
##### 脚本的代码实现
131+
132+
```python
133+
# 单次测试过程
134+
def test_process(self):
135+
# window 下用findstr，Mac下用grep
136+
cmd = "adb shell dumpsys cpuinfo | findstr org.chromium.webview_shell"
137+
self.result = os.popen(cmd)
138+
cpu_value = 0
139+
for line in self.result.readlines():
140+
cpu_value = line.split("%")[0]
141+
142+
current_time = self.get_current_time()
143+
self.all_data.append((current_time, cpu_value))
144+
```
145+
146+
147+
148+
