From b06aa643cac4ea815b9ae6aec6c09bf584c33bd6 Mon Sep 17 00:00:00 2001 From: Pablo de Lara Date: Fri, 4 May 2018 11:22:14 +0100 Subject: [PATCH] test/compress: add initial unit tests This commit introduces the initial tests for compressdev, performing basic compression and decompression operations of sample test buffers, using the Zlib library in one direction and compressdev in another direction, to make sure that the library is compatible with Zlib. Due to the use of Zlib API, the test is disabled by default, to avoid adding a new dependency on DPDK.

She\n" + "took down a jar from one of the shelves as she passed; it was\n" + "labelled `ORANGE MARMALADE', but to her great disappointment it\n" + "was empty: she did not like to drop the jar for fear of killing\n" + "somebody, so managed to put it into one of the cupboards as she\n" + "fell past it.\n\n" + " `Well!' thought Alice to herself, `after such a fall as this, I\n" + "shall think nothing of tumbling down stairs!

(Alice had no idea what Latitude was,\n" + "or Longitude either, but thought they were nice grand words to\n" + "say.)\n\n" + " Presently she began again. `I wonder if I shall fall right\n" + "THROUGH the earth!

No, it'll\n" + "never do to ask: perhaps I shall see it written up somewhere.'\n" + " Down, down, down. There was nothing else to do, so Alice soon\n" + "began talking again. `Dinah'll miss me very much to-night, I\n" + "should think!'

Do cats eat bats?' and sometimes, `Do\n" + "bats eat cats?' for, you see, as she couldn't answer either\n" + "question, it didn't much matter which way she put it. She felt\n" + "that she was dozing off, and had just begun to dream that she\n" + "was walking hand in hand with Dinah, and saying to her very\n" + "earnestly, `Now, Dinah, tell me the truth: did you ever eat a\n" + "bat?' when suddenly, thump! thump! down she came upon a heap of\n" + "sticks and dry leaves, and the fall was over.\n\n"; + +/* Snippet of Shakespeare play */ +static const char test_buf_shakespeare[] = + "CHARLES wrestler to Frederick.\n" + "\n" + "\n" + "OLIVER |\n" + " |\n" + "JAQUES (JAQUES DE BOYS:) | sons of Sir Rowland de Boys.\n" + " |\n" + "ORLANDO |\n" + "\n" + "\n" + "ADAM |\n" + " | servants to Oliver.\n" + "DENNIS |\n" + "\n" + "\n" + "TOUCHSTONE a clown.\n" + "\n" + "SIR OLIVER MARTEXT a vicar.\n" + "\n" + "\n" + "CORIN |\n" + " | shepherds.\n" + "SILVIUS |\n" + "\n" + "\n" + "WILLIAM a country fellow in love with Audrey.\n" + "\n" + " A person representing HYMEN.
