Will nonce increase even when the transaction fail?

Question

Will nonce increase even when the transaction fail?

For example,

nonce=0 -> tx succeed
nonce=1 -> tx succeed
nonce=2 -> tx fail

Then I want to send a new raw transaction, should I assign nonce as 2 or nonce as 3?

Thank you

Each transaction from an account must have an incremental nonce, regardless of whether or not the transaction succeeds. The MyCrypto knowledge base provides a good explanation of why Ethereum uses nonces.
