Why is the script writer for C# is the best tool for automatic browser testing?

In the world of fast-paced modern web development, automatic testing is more than just luxury-that is a must. Companies and developing startups require reliable, measured, and maintained automation frameworks to ensure the quality of their applications.

One of the most powerful tools available today is Scriptwriter for c#A strong browser automation framework by Microsoft that is tailored to the .NET ecosystem.

Are you just starting Browser automation at .net Or want to measure your automatic testing infrastructure, this guide will guide you through everything you need to know about using Scriptwriter with c# for testing the end to the high quality end.

Why use Playwright for C#?

PlayWright for C# offers a series of interesting features that make it a strong competitor for any C# browser testing frame:

• Cross-browser automation With Chromium, Firefox, and Webkit

• Wait automatically so that the elements are ready before interaction

• Isolation of parallel tests Using the independent browser context

• Support for modern web applications Like Spa, Iframes, and Shadow Dom

• Strong C# API to build a discharged automation script

Preparing Playwright in Project C#

Prerequisite

To start, make sure you have the following tools installed:

• .Net SDK (6.0 or newer)

• Visual Studio, vs Code, or Jetbrains Rider

Project initialization

Create a new console project and install the required playwright package:

party

Copyedit

Dotnet New Console -n Playwrightdemo
Playwrightdemo CD
Dotnet Add Microsoft.playwright Package

Now install the browser of the script writer:

For Windows:

party

Copyedit

Dotnet build
PWSH BIN/DEBUG/NET6.0/PLAYWright.PS1 Instal

For linux/macos:

party

Copyedit

Dotnet build
Bash bin/debug/net6.0/playwright.sh install

Your first drama script on C#

CSHARP

Copyedit

using Microsoft.playwright;

class program
{
Main Public Static ASYNC Duties ()
{
Using Var Drama Wright = Waiting for Drama Wright.Createasync ();
waiting for using a var browser = waiting for the drama wright.chromium.laununchasync (new () {headless = false});
var page = waiting for browser.newpageasync ();
waiting for the page.gotoasync (“https://playwright.dev”);
Await page.screenshotasync (new () {path = “scrayhot.png”});
}
}

This simple script launches a browser, navigating to the website, and captures screenshots.

The core concept of the script writer at .net

Understanding the building block of the script writer for C# is very important to design a reliable test suite.

• Browser: The actual browser engine (Chromium, Firefox, Webkit)

• BrowserContext: Isolated sessions like disguise mode

• Page: One tab or window in the context

Each context can have several pages and support the insulation of sessions Execution of parallel tests.

Element Interaction with Automatic Waiting

Playwright automatically waits for the DOM element ready before acting:

CSHARP

Copyedit

waiting for page.gotoasync (“https://example.com”);
waiting for the page.clickasync (“#send button”);
waiting for the page.fillasync (“#search”, “Playwright C#”);
waiting for the page.

This makes the test more stable and reduce errors related to time.

Use a locator for better control

Locators in Playwright gives developers a strong way to interact with page elements:

CSHARP

Copyedit

var button = page.locator (“#send button”);
waiting for button.clickasync ();

var activeitem = page.locator (“. Register”). Locator (“. Item.active”);

The locator supports the chain, filtering, and text-based queue for dynamic web applications.

Writing test using nunit with butt writers for C#

You can integrate the script writer with a test framework such as Nunit, Xunitor MSTEST.

Example: basic nunit test

CSHARP

Copyedit

[TestFixture]
Public class playwrighttests
{
Private iplaywright _playwright;
Private Ibrowser _browser;
personal ipage _page;

[SetUp]
Public ASYNC Task Arrangement ()
{
_PlayWright = Waiting for the drama Wright.Createasync ();
_browser = waiting for _playwright.chromium.laununhasync ();
_Page = waiting for _browser.newpageasync ();
}

[TearDown]
Public Async Task Teardown ()
{
waiting for _browser.disposeasync ();
_Playwright.dispose ();
}

[Test]
ASYNC Task for Public HomePagehascorrecttitle ()
{
waiting for _page.gotoasync (“https://playwright.dev”);
Assert.areequal (“Scriptwriter”, waiting for _page.titleasync ());
}
}

This setting allows you to start building that can be discussed, Automatic Testing Suite in C#.

The sophisticated features of the script writer for .net

Network demand mocks

CSHARP

Copyedit

Await page.routeasync (“**/API/Users/**”, ASYNC Route =>
{
Await route.fulfillasync (new ()
{
Status = 200,
Body = “[{\”id\”: 1, \”name\”: \”Test User\”}]”,
Contenttype = “Application/JSON”
});
});

Session -based authentication

CSHARP

Copyedit

waiting for the context.storagesteasync (new () {path = “author.json”});

Var Authcontext = Waiting for Browser.NewContextasync (New ()
{
Storagestatekat = “Auth.Json”
});

Real World Login Test with Script Writers for C#

CSHARP

Copyedit

[Test]
ASYNC Public UserCanlogin ()
{
waiting for _page.gotoasync (“https://example.com/login”);
waiting for _page.fillasync (“#email”, “[email protected]”);
waiting for _page.fillasync (“#password”, “Password123”);
waiting for _page.clickasync (“#login-bombol”);

waiting for _page.waitforsellectorasync (“. Dashboard”);
var welcome = waiting for _page.textcontentasync (“. Welcome-Message”);

Assert.that (Welcome, Dod.contain (“Welcome, Test User”));
}

The best practice for the measured C# test automation

Use the page object model (pom)

CSHARP

Copyedit

Loginpage Public Class
{
Private readully ipage _page;

Public loginpage (ipage page) => _Page = page;

ASYNC Public Task Loginasync (String, String Pass)
{
waiting for _page.gotoasync (“https://example.com/login”);
waiting for _page.fillasync (“#usename”, user);
waiting for _page.fillasync (“#password”, pass);
waiting for _page.clickasync (“#login-bombol”);
}
}

Voter strategy

• Button: has text (“send”)

• Data Test = Submitton

Timeout configuration

CSHARP

Copyedit

Var Context = waiting for the browser.newcontextasync (new () {navigationtimeout = 30000});
Await Page.Clickasync (“#Slow-Button”, New () {timeout = 60000});

CI/CD pipe integration

Examples of Azure Devops:

Yaml

Copyedit

Trigger:
– main

pool:
VMIMAGE: ‘Ubuntu-Latest’

ladder:
– Task: Usedotnet@2
Input:
Packagetype: ‘SDK’
Version: ‘6.0.x’

– Script: |
Dotnet build
Dotnet test
DisplayName: ‘Bangun and Test with the Writer of the Script for C#’

Conclusion

Scriptwriter for c# is a strong and reliable solution for a team that wants to automate the browser test at .Net Ecosystem.

From Cross-browser automation For real world testing scenarios, drama writers simplify the writing of the test while offering in -depth control and flexibility.

For company development teams and startups who want to increase quality assurance pipes, adopt Script writer in your C# project Can cause faster release, less bugs, and more measurable test infrastructure.
