A method for test data compression includes generating a plurality of test cubes, each test cube comprising test cube data. Each test cube is compared with at least one other test cube, as test cube pairs, to generate a compatibility rating for each compared test cube pair. The compared test cube pair with the highest compatibility rating is determined. The compared test cube pair with the highest compatibility rating is grouped into a test cube set. The remaining test cubes are grouped into test cube sets, as test cube pairs, based on the compatibility ratings of the compared test cube pairs. For at least one test cube set, a new codeword set is generated. Test cube data is grouped into blocks based on the new codeword set. Compression for the grouped test cube data is computed. A determination is made whether compression is improved as compared to a previous codeword set. If compression is not improved, the test cube set is encoded with the new codeword set to generate an encoded test cube set. If compression is improved, the previous codeword set is set as the new codeword set, and the steps are repeated beginning with generating a new codeword set. The encoded test cube sets are concatenated to form a decompressed encoded test stream. The decompressed encoded test stream is compressed to form a compressed test stream.
