AutoFixture ThrowingRecursionBehavior fix
To fix error in tests add followings lines of code. Example in xUnit:
Using the OpenAI API in a C# console application
Repo: https://github.com/kaajoj/OpenAIApp To run it, you need to provide your own API key. Sample code with request to generate new image: https://github.com/kaajoj/OpenAIApp/blob/cc1881a985365683c90484e9cb2dca7c1361b810/OpenAIApp/OpenAI.cs#L52 Sample results of image generation: Big dogs flying a plane to Mars Dogs like top gun
New console template – use user secret
dotnet user-secrets init set a secret: dotnet user-secrets set “API_KEY” “test123” use UserSecretsId (from .csproj file) in AddUserSecrets()
Truffle test – ReferenceError: accounts is not defined
When you run command ‘truffle test’ and get error:“ReferenceError: accounts is not defined” To fix this, use below code line:contract(“Contract”, async (accounts) => {} and put test code between brackets e.g.:
Error: Number can only safely store up to 53 bits
I got this error: ‘Error: Number can only safely store up to 53 bits’ when using toNumber function: Quick fix using BigInt:
Truffle test – network error
truffle(ganache)> truffle testError: You must specify a network_id in your ‘ganache’ configuration in order to use this network. Go to config file: truffle-config.js -> uncomment ‘development’ section in ‘networks’. Change port if you have a different one in Ganache, e.g. modfiy from 8545 to 7545. Save file -> back to console -> run command: ‘truffleContinue reading “Truffle test – network error”
Create new ERC20 token – smart contract
Sample smart contract to create your own token: The same code, but with a hard-coded name, symbol and initial supply: Sources:https://docs.openzeppelin.com/contracts/4.x/erc20https://solidity-by-example.org/app/erc20/https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v4.0.0/contracts/token/ERC20/ERC20.sol
Mock IConfigurate in xUnit
If you want mock IConfiguration use following code: or copy secrets.json configuration file to output directory: projectName\bin\Debug\netcoreapp3.1 and then use following code in ContextFixture: Config json file e.g. secrets.json:
Secret storage in .NET
Enable secret storage:Type “dotnet user-secrets init” into Package Manager Console <UserSecretsId> can be found in .csproj file. Set a secret (Package Manager Console):dotnet user-secrets set “ApiKey” “test123” or to remove it:dotnet user-secrets remove “ApiKey” To check if exists:dotnet user-secrets listorManage secret through GUI -> right click on project -> Manage User Secrets -> it opensContinue reading “Secret storage in .NET”
