CoTester vs Other Agentic AI Platforms for Testing

Here’s a fact: software testing has evolved over the years.

Gone are the days when you’d painstakingly write scripts for every scenario or settle for incomplete coverage due to resource constraints. Testing cycles are tighter today, apps are more complex, and demand for quality is greater than ever.

Naturally, AI tools have stepped up massively in the last few years. Gartner reports that 60% of companies automate software testing to improve product quality, while 41% do so to optimize departmental agility.

Moreover, 57% of IT and software engineering leaders believe Generative AI will be widely used in software testing, especially for predicting common issues or bugs, by 2026.

What if we told you there’s an Agentic AI that’s onboardable, trainable, and taskable? It can easily integrate into your team, adapt to your workflows, and test your software like an experienced human tester.

Meet CoTester by TestGrid.

It’s built to go beyond ChatGPT’s capabilities. It can write test cases for your web app or website, assist with real-time debugging, and execute them on various browsers.

How, you ask?

Based on the testing scenarios and user stories you provided. What’s more—there will be no extensive retraining or process overhauls.

But what are CoTester’s clear strengths, and where does it fit in the testing landscape? How does it measure up against other AI test automation platforms? While they bring advantages, let’s do a comparative analysis in this blog post.

CoTester by TestGrid

CoTester by TestGrid is the world’s first AI software tester pre-trained on advanced software testing fundamentals and Software Development Life Cycle (SDLC). It frees valuable time for your team and enables them to focus on more complex testing scenarios.

CoTester relies on predefined commands even when using natural language. This means it uses true AI to understand user intent without rigid syntax constraints, unlike other AI testers who are primarily syntax-driven.

You can interact with it using plain language without a predefined script, making it simple and intuitive. Just type “Hi” into CoTester’s chat interface to start a conversation.

Train CoTester on your testing approach in two ways: file uploads and URL pasting.

You can upload user stories in various formats, such as PDF, Word, and CSV for file uploads. These files build a knowledge base that CoTester uses to generate accurate test cases. The more detailed the user story, the better the results.

With URL pasting, simply enter a link (e.g., “https://public.testgrid.io/signup”), and CoTester will analyze the website in the background. This approach is great for testing specific web pages or forms, as it uses the site’s content to generate relevant test cases.

All data uploaded to CoTester remains secure and isolated within your organization’s instance. Your proprietary information is not shared or used to train the tool, ensuring complete confidentiality.

Features

• Maintain a centralized repository for all files and assets, simplifying organization and retrieval; add or remove files using the Document icon and the “+Add More” button without overwriting existing data

• Receive detailed test case descriptions and a step-by-step editor for automation workflows, showcasing the sequence of interactions with elements like web forms and using placeholder data for missing inputs

• Use the Debug button to execute AI-generated test cases, verify workflows, and adjust steps as needed; view execution logs, screenshots, and results to identify and resolve issues

• Manually edit generated test cases by adding or removing steps, saving time on refining workflows; use the chat interface for precise instructions to tweak test cases

Industry-specific applications

CoTester is a domain-specific expert system for testing websites and web apps in various industries, including BFSI, eCommerce, telco, healthcare, and travel.

Who can use CoTester?

Quality Assurance (QA) engineers, beginner automation testers, and agile teams will find CoTester helpful.

Upcoming Developments in CoTester

CoTester can only be used to test websites and web applications. Support for mobile testing is currently under development, so its reach will soon extend to mobile applications.

Integration with Jira workspaces to automatically fetch user stories, test cases, bugs, and other project details is planned as part of the future roadmap. Additional integrations with platforms like Slack, Trello, ClickUp, Miro, Asana, GitHub, and Microsoft Teams are also in the pipeline.

What to Consider When Choosing an Automation Tool for Software Testing

Before deciding, understand how a platform fits into your testing strategy. Here are four key areas to evaluate:

• Cost-efficiency: Consider the total cost of ownership. Look beyond the license fee—calculate how much time the tool saves, how it reduces manual effort, and the support you’ll need to get it running smoothly.

• Industry use cases: Check if the platform has proven applications in areas like healthcare, finance, or retail. If so, then it’s a sign that it can handle specific challenges like high-volume transactions or regulatory compliance.

• Tech stack compatibility: Just because you’re adding a new tool to your ecosystem doesn’t mean your existing systems need an overhaul. It should integrate easily with your framework, CI/CD pipelines, and reporting systems.

• Customization flexibility: Can the tool be personalized based on your testing strategy and business requirements? If yes, does it come with a steep learning curve? Find out if it supports designing and modifying tests to match your edge cases and priorities.

Conclusion

AI is redefining software testing, pushing the boundaries of what traditional tools can achieve.
