Espresso command line multiple packages not working

It works perfectly fine for 1 package: 

❯ 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)

However, it detects 0 test when I use multiple packages; therefore, skipping running all the tests! 

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


Time: 0

OK (0 tests)

What's happening?
