Blockchain contains the list of records in a chain of blocks that are made secure using cryptography. Each block comes with a unique cryptographic hash for previous blocks also validates and allows seeing transactions details between two or more participants. The blockchain is managed through the P2P (peer-to-peer) network for addressing a protocol and creating new blocks of information.
The testing of the application takes place based on the functionality of Blockchain, which the test engineer does, such as:
Some codes are executed to check the cases. Please, click on the link Ethereum Tester, it provides a tool for testing the Ethereum blockchain based applications.
Input/output Data Format:
The Ethereum library utilizes this format:
The parameter will undertake the given value.
Installation code:- pip install eth-tester
Development code:- pip install -e . -r requirement-dev.txt
Execute the code for testing:-py.test tests
Otherwise, install tox to execute the test suite.
1) eth_tester.EthereumTester (backend=None, validator=None,
normalizer=None, auto_mine_transactions=True, forks_blocks=none)
2) backend: The backend chain that’s being used.
3) validator: The validator used.
4) normalizer: the normalizer used.
-allow auto mine transactions
-disallow auto mine transactions
6) fork_blocks:- Several Block number will be activated consisting of block network.
1) from:- the address of the account being used to sending the transaction details (hexadecimal string).
2) to:- the address of the account being used to receive the transaction.
An empty string will be used to switch towards contract creation (hexadecimal string).
3) gas:- to set the gas limit for transaction detail executed (integer).
4) gas_price:- fix the price per unit of gas in wei that’ll be paid for the transaction details executed (integer).
5) value:- the number of ether in wei sent to others which give the transaction details (integer).
6) data:- gives balance details of the transaction (hexadecimal string).
