title: How to set the expect calling counts for void method when using EasyMock + PowerMock?
body: <pre><code>File mockFile = createMockAndExpectNew(File.class, fileParentPath+fileName);
  RandomAccessFile mockRandomAccessFile = createMockAndExpectNew(RandomAccessFile.class, mockFile, "rw");
  mockRandomAccessFile.seek(0L);
  </code></pre>
  
  <p>I want to set invocation counts for this expected void method, but I don't know what to do.</p>
