Always ensure proper cleanup of resources in tests to prevent memory leaks. When using EmbeddedChannel, call readOutbound() to process all expected buffers and finish() at the end of your test to verify no resources remain and release any remaining buffers. This is particularly important for tests involving data buffers, channels, and I/O operations.
Always ensure proper cleanup of resources in tests to prevent memory leaks. When using EmbeddedChannel, call readOutbound() to process all expected buffers and finish() at the end of your test to verify no resources remain and release any remaining buffers. This is particularly important for tests involving data buffers, channels, and I/O operations.
Example:
@Test
public void testBufferHandling() {
EmbeddedChannel channel = new EmbeddedChannel(new YourHandler());
// Write test data
channel.writeInbound(Unpooled.wrappedBuffer(testData));
// Read and verify all expected results
ByteBuf result1 = channel.readInbound();
assertEquals(expectedData1, result1);
result1.release();
ByteBuf result2 = channel.readInbound();
assertEquals(expectedData2, result2);
result2.release();
// Ensure channel is properly closed and no resources are leaked
assertFalse(channel.finish());
}
This pattern prevents resource leaks that can accumulate during test runs and ensures that your tests properly validate the complete processing of data.
