JUnit jupiter extension for Mockito construction and static mocking.

```xml

    io.github.boolivar

    mockito-inline-extension

    1.0.0

    test

```

```gradle

testImplementation "io.github.boolivar:mockito-inline-extension:1.0.0"

```

Construction mock

---

Mockito:

```java

class FooTest {

    @Test

    void testFoo() {

        try (MockedConstruction mocked = mockConstruction(Foo.class)) {

            Foo foo = new Foo();

            when(foo.method()).thenReturn("bar");

            assertEquals("bar", foo.method());

            verify(foo).method();

        }

    }

}

```

MockitoInlineExtension:

```java

@ExtendWith(MockitoInlineExtension.class)

class FooTest {

    @ConstructionMock(Foo.class)

    @Test

    void testFoo() {

        Foo foo = new Foo();

        when(foo.method()).thenReturn("bar");

        assertEquals("bar", foo.method());

        verify(foo).method();

    }

}

```

`@ConstructionMock` supports list of classes to mock for single test. Test method can accept arguments of type `MockedConstruction` parameterized by mocked type:

```java

@ConstructionMock({Foo.class, Bar.class})

@Test

void testFooBar(MockedConstruction mockedFoo, MockedConstruction mockedBar) {

}

```

Optional mock initialization method can be provided with the same name as test, accepting actual mock and `MockedConstruction.Context` arguments:

```java

void testFooBar(Foo mock, MockedConstruction.Context context) {

}

void testFooBar(Bar mock, MockedConstruction.Context context) {

} 

```

Static mock

---

Mockito:

```java

class FooTest {

    @Test

    void testFoo() {

        try (MockedStatic mocked = mockStatic(Foo.class)) {

            mocked.when(Foo::method).thenReturn("bar");

            assertEquals("bar", Foo.method());

            mocked.verify(Foo::method);

        }

    }

}

```

MockitoInlineExtension:

```java

@ExtendWith(MockitoInlineExtension.class)

class FooTest {

    @StaticMock(Foo.class)

    @Test

    void testFoo(MockedStatic mocked) {

        mocked.when(Foo::method).thenReturn("bar");

        assertEquals("bar", Foo.method());

        mocked.verify(Foo::method);

    }

}

```
