用Mockito模擬靜態方法我寫了一家工廠來生產java.sql.Connection物體：public class MySQLDatabaseConnectionFactory implements DatabaseConnectionFactory {
@Override public Connection getConnection() {
try {
return DriverManager.getConnection(...);
} catch (SQLException e) {
throw new RuntimeException(e);
}
}}我想驗證傳遞給DriverManager.getConnection，但我不知道如何模擬靜態方法。我使用JUnit 4和Mockito作為測試用例。有一個好的方法來模擬/驗證這個特定的用例嗎？

@Test
public void shouldVerifyParameters() throws Exception {
//given
PowerMockito.mockStatic(DriverManager.class);
BDDMockito.given(DriverManager.getConnection(...)).willReturn(...);
//when
sut.execute(); // System Under Test (sut)
//then
PowerMockito.verifyStatic();
DriverManager.getConnection(...);
}
