How can I test logging in a Go application?

You can use the testing package in Go to create unit tests for your login functionality. Would you like an example?

Yes, please provide an example of a test for a login function.

Sure! Here's a simple example:

func TestLogin(t *testing.T) {
    req, err := http.NewRequest("POST", "/login", nil)
    if err != nil {
        t.Fatal(err)
    }
    // Set up your test environment and expectations here
}

This sets up a basic test for a login endpoint.

What should I include in the test to check for valid and invalid logins?

You should check the response status code and the response body for both valid and invalid credentials. You can use table-driven tests for this.
