Python Buffer.read Examples

Example #1

def test_LIFO_read():
    buf = Buffer(yield_next="newest")
    buf.write(["1", "2", "3"])
    assert len(buf.data) == 3

    assert buf.read() == ["3"]
    assert buf.read() == ["2"]
    assert buf.read() == ["1"]
    assert len(buf.data) == 0

Example #2

def test_FIFO_read():
    buf = Buffer()
    buf.write(["1", "2", "3"])
    assert len(buf.data) == 3

    assert buf.read() == ["1"]
    assert buf.read() == ["2"]
    assert buf.read() == ["3"]
    assert len(buf.data) == 0

Example #3

def test_read_empty():
    buf = Buffer()
    assert buf.read() == []
    assert len(buf.data) == 0
