When I turn on Xdebug, phpunit bootstrap setting didn't work

Question

I have a problem when using Xdebug and PHPUnit.
Because I want to use AspectMock, so I create bootstrap in phpunit.xml configuration and it goes well.
However, when I try to turn on Xdebug to generate coverage report, it didn't use my bootstrap setting. (I'm not sure it's because it didn't read or the bootstrap setting was been covered)
I don't know why or where to find bugs.

Here is the result example(I have dump my mock): (it's the same with -c phpunit.xml)

$vendor/bin/phpunit test.php

array: [
  "status" => "successed", 
  "data" => ["test" => "test"]
]

$vendor/bin/phpunit --coverage-html build/coverage test.php (Because data didn't mock)

array: [
  "status" => "failed", 
  "data" => []
]

php.ini

[Xdebug]
zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so
xdebug.remote_enable=On

$php -v
