PowerMockito を使用してこのメ​​ソッドの呼び出しを確認するにはどうすればよいjava.util.concurrent.Executors.newSingleThreadExecutor()ですか? 以下のクラスとそのテストを参照してください。なんらかの理由で、PowerMockito は、このモックとのやり取りがまったくなかったと言っています。

package demo;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class MyClass {
    public void init() {
        ExecutorService executor = Executors.newSingleThreadExecutor();
    }
}

.

package demo;
import java.util.concurrent.Executors;
import org.junit.Ignore;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(Executors.class)
public class MyTest {

    @Test
    public void testName() throws Exception {
        PowerMockito.mockStatic(Executors.class);

        new MyClass().init();

        PowerMockito.verifyStatic();
        Executors.newSingleThreadExecutor();
    }
}

次のエラー メッセージが表示されます。

Wanted but not invoked java.util.concurrent.Executors.newSingleThreadExecutor();
Actually, there were zero interactions with this mock.

気にしないでください、私は自分の問題を見つけました。次のようになります。 @PrepareForTest(MyClass.class)

powermock FAQとexamplesによると。

verifyStaic() メソッドを使用して、特定のクラスに対して呼び出された静的メソッドの数をカウントできます。PowerMockito の代わりに Mockito の verify メソッドを使用できます。
