golang before all tests

To run tests in Go, you can use the built-in testing package, testing. Here are the steps to perform before running all the tests in Go:

1. Import the testing package: In your Go source file, you need to import the testing package at the top of the file. This package provides the necessary functions and types for writing tests.

import "testing"

1. Define your test functions: Write individual test functions that begin with the word "Test" followed by a descriptive name. Each test function should take a single argument of type *testing.T, which is used for reporting test failures and logging test results.

func TestMyFunction(t *testing.T) {
    // Test logic goes here
}

1. Write your test logic: Inside each test function, you can write the logic to test your code. You can use various testing functions provided by the testing package, such as t.Errorf, t.Fatalf, t.Run, etc., to report failures, errors, or subtests.

func TestMyFunction(t *testing.T) {
    // Test logic goes here
    if result != expected {
        t.Errorf("Expected %v, but got %v", expected, result)
    }
}

1. Run the tests: To run all the tests in your Go package, you can use the go test command in your terminal. Navigate to the directory containing your Go source files and run the following command:

go test

This command will automatically discover and execute all the test functions in your package, providing output indicating the number of tests passed or failed.

That's it! By following these steps, you can run tests in Go using the testing package. It's important to note that the testing package follows certain conventions for test function names and test file organization, so make sure to familiarize yourself with these conventions to ensure your tests are executed correctly.
