counting times private method is called with PowerMockito - unit-testing

Question

I'm trying to get the number of times a private method has been called.
I can do this with mockito for public methods:
Mockito.verify(mockedObject, times(numberOfTimes)).methodToBeChecked();
Is there an equivalent for PowerMockito?
I dont want tu use spy.
Thanks in advance.

Yes, it is.
Here my dependencies:
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>2.28.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito2</artifactId>
<version>2.0.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>2.0.2</version>
<scope>test</scope>
</dependency>
The class under test:
public class A {
private void _test(){
}
public void test(){
for (int i = 0; i < 10; i++) {
_test();
}
}
}
My Junit:
#RunWith(PowerMockRunner.class)
#PrepareForTest({A.class})
public class ATest {
private A a;
public ATest() {
}
#Before
public void setUp() {
a = PowerMockito.spy(new A());
}
/**
* Test of test method, of class A.
*/
#Test
public void testTest() throws Exception {
a.test();
PowerMockito.verifyPrivate(a, Mockito.times(10)).invoke("_test");
}
}
But using powermockito has drawbacks:
you cannot monitor coverage with tool as Jacoco and on the fly instrumentation
probably you are developing an hard to test design: you should use it only if you are working to a legacy and impossible to change code
