How do I write integration tests with Echo in Go?

To write integration tests for your Echo application in Go, you can make use of the built-in testing library along with the Echo framework's HTTP test capabilities. The following example demonstrates how to set up your integration tests effectively.


    package main

    import (
        "net/http"
        "net/http/httptest"
        "testing"

        "github.com/labstack/echo/v4"
    )

    func TestHelloHandler(t *testing.T) {
        e := echo.New()

        // Define a test route
        e.GET("/hello", func(c echo.Context) return c.String(http.StatusOK, "Hello, World!")
        })

        // Create a test request
        req := httptest.NewRequest(http.MethodGet, "/hello", nil)
        rec := httptest.NewRecorder()
        c := e.NewContext(req, rec)

        // Call the handler
        if err := e.Handler(c); err != nil {
            t.Fatal(err)
        }

        // Check the response
        if rec.Code != http.StatusOK {
            t.Errorf("Expected status code %d, got %d", http.StatusOK, rec.Code)
        }
        if rec.Body.String() != "Hello, World!" {
            t.Errorf("Expected body %q, got %q", "Hello, World!", rec.Body.String())
        }
    }
