Here are some best practices for testing and debugging Go code:
Write unit tests: Unit testing is an important part of Go development. Write test functions for each package, and make sure that they are testing the expected behavior.
Use the standard testing package: Go has a built-in testing package that provides a simple and efficient way to write tests. Use the testing package to write your unit tests.
Test for edge cases: Make sure to test for edge cases and boundary conditions. This will help to catch any unexpected behavior that may occur in the future.
Use a code coverage tool: Use a code coverage tool to check how much of your code is being exercised by your tests. This will help you to identify any areas of your code that may need more testing.
Use a debugger: Go comes with a built-in debugger, which can be very helpful in debugging your code. Use the debugger to step through your code and identify any issues.
Use logging: Add logging statements to your code to help you identify issues. Make sure to log relevant information, such as the function name and any relevant input values.
Use profiling: Use profiling tools to identify performance bottlenecks in your code. This will help you to optimize your code and make it more efficient.
Use error handling: Make sure to handle errors in your code. Use the built-in error type and handle errors in a way that makes sense for your application.
Use tools for static analysis: Use tools for static analysis, such as GoLint and Go Vet, to identify potential issues in your code.
Follow best practices: Follow best practices for Go development, such as using short variable names, avoiding global variables, and using the defer statement to handle resource cleanup. This will help you to write cleaner, more maintainable code.
