I'm implementing IDEA algorithm in java and I need test vectors for the algorithm that include plaintext,ciphertext and keys in each step to verify my code.

There is one set of test vectors at the end of the paper describing the standard; it includes round keys and the transformation of the plaintext to ciphertext for each round, but it doesn't zoom in on the values within the rounds.

The values given in the IDEA paper (mentioned above) are kinda useless, they're decimal numbers representing internal states rather than { key, plaintext, ciphertext } triplets. Here are some triplets from the original ETH reference implementation of IDEA:
