Go Lang API testing in Playwright

Testing APIs written in Go using Playwright involves a few steps since Playwright is primarily a Node.js library. However, there is a Go library for Playwright maintained by the community that you can use. Here’s a general approach to testing your Go APIs with Playwright:

1. Install Playwright for Go: You can install the Playwright Go library using the following command:

   go get -u github.com/playwright-community/playwright-go
   

2. Write Test Cases: You’ll write test cases using the Playwright API to send requests to your Go server and verify the responses. Below is a sample code snippet that demonstrates how you might write a test case to check the response of an API endpoint:

   package main
   
   import (
       "fmt"
       "github.com/playwright-community/playwright-go"
   )
   
   func main() {
       pw, _ := playwright.Run()
       browser, _ := pw.Chromium.Launch()
       page, _ := browser.NewPage()
   
       // Replace with your API endpoint
       response, _ := page.Goto("http://localhost:8080/your-api-endpoint")
   
       // Check if the response status is 200 (OK)
       if response.Status() == 200 {
           fmt.Println("API endpoint is working as expected.")
       } else {
           fmt.Println("API endpoint is not working as expected.")
       }
   
       _ = browser.Close()
       _ = pw.Stop()
   }
   

3. Run Your Tests: Execute your tests using the Go command line tool. If you have set up your tests in a file named api_test.go, you can run them with:

   go test api_test.go
   

For more detailed information and examples, you can refer to the Playwright for Go GitHub repository and the Playwright API testing guide. These resources should give you a good starting point for writing and running your API tests using Playwright in Go.

Remember, since Playwright is a Node.js library, the community-driven Go version may not have all the features of the official Playwright library, and you might need to handle some of the inter-language interoperability yourself. Keep this in mind as you develop your tests.

Thank you Naimish for your response with the detailed explanation.

When I run the program (File name – api_test.go) , I get this message, do you have any idea ?

Note :- API end point is running in my local, i am able to access the same endpoint in postman
