Functional Test Correction in Bitcoin: “JSONRPCEXception: The method is not found”
Bitcoin’s functional tests are essential to ensure the correctness of blockchains and wallets. Sometimes, however, these tests fail with a mysterious error message, JSONRPCEXPICECTICE: The method is not found (-32601). This article goes through three general functional tests that failed in the ‘test_runner.py’ file and we provide solutions to solve the problem.
Test 1: Test_Coins
The Test_Coins test checks if the coins are properly created. It is waiting for a specific method of method in the block chain with the right inlet parameters.
solution
Make sure the Createcoin method is implemented in the” blockchain.py “file and transmit the requested arguments (coinme, quantity) to the expected method invitation:
`Python
blockchain.py
Def Createcoin (Coinme, Quantity, Pubkey):
...
Make sure this implementation meets the test expectations.
Test 2: TEST_COINSGETTRANAsance
The Test_Coinsget Transaction test checks if the coin event is retrieved correctly. It is waiting for a specific method of method in the block chain with the right inlet parameters.
solution
Check that Blockchain.pyGettransaction "method corresponds to the expected signature of the action:
Python
blockchain.py
Def Gettransaction (ID):
...
Make sure this implementation meets the test expectations. If the solution does not solve the problem, make sure the method call is correct and transmits the required arguments.
Test 3: Test_Bytes
Test_bytes test checks IFTEs are sent correctly from JSON -RPC. It is waiting for a specific method of method in the block chain with the right inlet parameters.
solution
Make sure that the transmission method of the blockchain.pyfile corresponds to the expected signature of the action:
Python
blockchain.py
Def Sendbytes (ID, data):
...
Make sure this implementation meets the test expectations. If the solution does not solve the problem, check that the method invitation is correct and transmits the required arguments.
Additional tips
- Make sure all the tests are running before you try to repair the `test_runner.py file.
- Use error correction or print clauses to check the variables and operational call tests.
- Consider adding tasks and logging in to help your tests to help diagnosis.
By following the thesis, you should be able to identify and fix a problem that causes “JSONRPCEXPTICectice: The method is not found” in your functional Bitcoin tests.
