Espresso命令行多个包不工作

对于一个包装来说,它非常适用:

❯ adb shell 'am instrument -w -e package com.myapp.package1 com.myapp.test/com.myapp.MyTestRunner'

com.myapp.package1.ClassXTest:.......

Time: 22.288

OK (7 tests)

❯ adb shell 'am instrument -w -e package com.myapp.package2 com.myapp.test/com.myapp.MyTestRunner'

com.myapp.package2.ClassYTest:.....

Time: 6.959

OK (5 tests)

但是,当我使用多个包时,它检测到0个测试;因此,跳过运行所有测试!

❯ adb shell 'am instrument -w -e package com.myapp.package1,com.myapp.package2 com.myapp.test/com.myapp.MyTestRunner'


Time: 0

OK (0 tests)

怎么了?
