Bitcoin functional errors tests: “Jsonrpcexceptte: the method was not found”
Bitcoin functional tests are necessary to guarantee the correctness of blockchain and wallet. However, sometimes these tests fail with a mysterious error message, “Jsonrpcexepte: The method is not found (-32601). In this article we will undergo three joint functional tests that have failed in the Test_runner.py file and solutions were provided to solve the problem.
Test 1: Test_Coins
The Test_Coins' test checks that the coins are created correctly. It expects a specific method of calling blockchain with normal input parameters.
Decision
Make sure that the "creatcoin" method is implemented in the "blockchain.py" file and pass the necessary arguments (Name Coinname, ‘Sum’, ‘Pubkey’) to the expected method of the method:
`Python
Blockchain.py
Defreatecoin (Coinname, Sum, Pubkey):
...
Check if this implementation meets test expectations.
Test 2: Test_Coinsgettranstion
Test_Coinsgettranstion 'checks that the coin transaction is obtained correctly. It expects a specific method of calling blockchain with normal input parameters.
Decision
Check if the "Gettranstion" method in the file "Blockchain.py" is the same with the expected signature of this function:
Python
Blockchain.py
Def Gettranstion (ID):
...
Check if this performance meets test expectations. If the solution does not solve the problem, make sure that the connection is correct and sends the necessary arguments.
Test 3: Test_bytes
The test_bytes test checks if bytes are correctly sent via JSON-RPC. It expects a specific method of calling blockchain with normal input parameters.
Decision
Check if the “Sendbytes” method in the “blockchain.py” file corresponds to the expected signature of the function:
`Python
Blockchain.py
Deftbytes (ID, data):
...
Make sure this performance meets test expectations. If the solution does not solve the problem, check that the connection is correct and sends the necessary arguments.
additional tips
- Make sure that all tests are performed before trying to eliminate the
Test_Runner.pyfile error.
- Use a debuger or printed operators to check the variables and functional calls when performing the test.
- Consider adding more errors and introducing tests to help diagnose problems.
According to these steps, you must be able to identify and solve the problem, causing “jsonrpcexception: a method not found” in your functional bitcoin tests.
