Impact of Technical Debt on Software Testing

Sapna Soni — Wed, 09 Apr 2025 05:08:55 +0000

Technical debt is a critical concept that refers to the long-term costs associated with taking shortcuts or making quick fixes. While it can enable faster delivery of products, it often leads to significant challenges in maintaining quality, especially in testing.

Let’s dive in to explore how technical debt affects test processes, the risks involved, and practical approaches to manage it effectively.

Understanding Technical Debt in Testing
Technical debt arises when teams prioritize immediate results over long-term quality, often due to tight deadlines or resource constraints. In testing, this manifests as:

Poorly documented Test Strategy document: A poorly documented Test Strategy can result from insufficient attention during the test planning phase, leading to confusion and ambiguity in the testing process later in the execution cycle.
Skipping Test Refactoring: Neglecting to update tests can lead to disorganized test suites that are hard to maintain and prone to introducing new bugs.
Postponing Automation: Delaying the implementation of automated tests results in incomplete coverage and unreliable test outcomes, increasing future workload.
Inadequate Documentation: Poor documentation complicates onboarding for new team members and hinders existing members from efficiently referencing past work.

These shortcuts may seem beneficial initially, allowing teams to meet deadlines and respond quickly to changing requirements. However, the accumulation of technical debt can lead to severe long-term consequences.

Long-Term Costs of Ignoring Technical Debt

Increased Maintenance Costs: What begins as a minor oversight can escalate into a major issue. For example, failing to refactor a test suite can transform a simple cleanup task into an extensive project that consumes significant resources.
Higher Risk of Bugs and Regressions: Insufficient test coverage and flaky tests increase the likelihood of bugs slipping through. These issues not only degrade software quality but also erode trust among users and stakeholders.
Increased Manual Work: Failing to implement automation can lead to tests being executed manually, prolonging the overall test cycle. Repeated manual testing may cause frustration and dissatisfaction among testers, ultimately reducing the team’s productivity.

Strategies for Managing Technical Debt in Testing

Prioritize Refactoring: Incorporate regular refactoring sessions into your workflow to keep test suites organized and maintainable. This will help avoid larger issues down the line.
Automate Early: Invest time in automation as soon as feasible. This not only improves coverage but also reduces manual testing effort over time.
Enhance Documentation: Maintain up-to-date documentation for tests and processes to facilitate knowledge transfer within the team.
Communicate with Stakeholders: Clearly articulate the implications of technical debt to product managers and stakeholders. Frame discussions around how addressing technical debt can enhance product stability and user satisfaction.

Conclusion
I have had these technical debts some way or the other in my work.

Create Playwright Tests with Codegen

Sapna Soni — Tue, 08 Apr 2025 10:50:10 +0000

Playwright, an open-source automation library developed by Microsoft, has seen a rapid rise in popularity which is attributed to its modern features and capabilities that address the limitations of traditional testing frameworks like Selenium.

We will utilize Visual Studio 2022 along with C# and NUnit to develop a straightforward example that showcases the fundamental features of Playwright.

Step 1: Prerequisites

Install Visual Studio:
Ensure you have Visual Studio 2022 (or later) installed.
Install Node.js:
Download and install Node.js
Verify the installation by running:

node -v

Install Playwright Browsers: By default, Playwright installs the following three browsers: Chromium, Firefox, and Webkit.

Open a CMD or PowerShell window from a working directory.
Execute the following command to install Playwright browsers and their dependencies.

npx playwright install

Step 2: Create a New NUnit Project

Open Visual Studio and create a new project:
Select the NUnit Test Project template.
Name the project, e.g., PlaywrightSample
Confirm that the project contains a default test file, e.g., UnitTest1.cs

Step 3: Install Playwright NuGet Packages

Right-click on your project in Solution Explorer and select Manage NuGet Packages.
Search for and install the following packages:
Microsoft.Playwright
Microsoft.Playwright.NUnit
Microsoft.Playwright.TestAdapter
Step 4: Record Tests using Codegen

Playwright offers a GUI called Codegen to record user actions from start to finish. It also includes various types of assertions such as assert visibility, assert text, and assert value. Codegen is a great tool as it allows users to interact with a web page while Playwright records these actions in real-time. After recording, Codegen generates code snippets in various programming languages such as TypeScript, JavaScript, Python, and C#. This allows users to select the language they are most comfortable with.

To record tests in Playwright, we execute the following command in PowerShell window.

npx playwright codegen https://www.automationexercise.com

This command starts the recorder and opens 2 windows, (1) a Playwright Inspector window as in Figure 1, and (2) a browser window showing the home page of the site, as shown in Figure 2.

Make sure to select the option NUnit from the Target dropdown as we are writing NUnit test with C#.

Figure 1- Playwright Inspector window

Figure 2- Site Home Page

Now perform the below actions on browser:

Adding an assertion to make sure that the home page loads successfully
Navigating to Products link
Scrolling down to first product and click on view product
Click on Add to cart on the product details page
Adding assertion to make sure the product is added to cart
Click on Cart to view the cart details
Adding assertion to see if the added product is listed in the cart

Here is the code generated for the test case above:

using Microsoft.Playwright.NUnit;
using Microsoft.Playwright;

[Parallelizable(ParallelScope.Self)]
[TestFixture]
public class Tests : PageTest
{
    [Test]
    public async Task MyTest()
    {
        await Page.GotoAsync("https://www.automationexercise.com/");
        await Expect(Page.Locator("#header")).ToContainTextAsync("Home");
        await Page.GetByRole(AriaRole.Link, new() { Name = " Products" }).ClickAsync();
        await Page.Locator(".choose > .nav > li > a").First.ClickAsync();
        await Page.GetByRole(AriaRole.Button, new() { Name = " Add to cart" }).ClickAsync();
        await Expect(Page.Locator("#cartModal")).ToContainTextAsync("Added!");
        await Page.GetByRole(AriaRole.Button, new() { Name = "Continue Shopping" }).ClickAsync();
        await Page.GetByRole(AriaRole.Link, new() { Name = " Cart" }).ClickAsync();
        await Expect(Page.Locator("#product-1")).ToContainTextAsync("Blue Top");
    }
}

Step 5: Execute the test

Once the code is generated, simply copy and paste it into your project’s test class, and run the test. By default, the test runs in headless mode using the Chromium browser. In order to see the browser and use Firefox instead, we created a file called application.runsettings.

Right-click on the Visual Studio project name
Select Add -> New Item
Select XMLFile.xml and rename it to application.runsettings)

<?xml version="1.0" encoding="utf-8"?>
<!-- Playwright Settings-->
<RunSettings>
 <Playwright>
  <BrowserName>firefox</BrowserName>
  <LaunchOptions>
   <Headless>false</Headless>
  </LaunchOptions>
 </Playwright>
</RunSettings>

From the Test menu in Visual Studio, select: Test -> Configure Run Setting -> Select Solution Wide runsettings File, then select the XML file we just created application.runsettings.

Voilaa!! You are all set.

Build the solution and run your test.
