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. Platforms leveraging agentic AI for software testing are transforming the way teams generate, execute, and maintain tests here’s a deep dive into agentic AI testing for those looking to understand the landscape. 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 AI agent for software testing that’s onboardable, trainable, and taskable? It brings unmatched speed, flexibility, reliability, and built-in test orchestration, and is always ready to test whenever you are.

Meet CoTester 2.0 by TestGrid.

Think of it as ChatGPT, but it’s purpose-built for software testing. It learns from your product context, adapts to your QA workflows, and then writes the test code for you. What’s more, there’s no need for extensive retraining or process overhauls.

CoTester is your always-available teammate.

But what are its 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 2.0 by TestGrid

CoTester is the first enterprise-grade AI agent for software testing, with a deep understanding of testing workflows and enterprise QA practices.

You can task it using plain language without a predefined script, making it intuitive and easy to use. Typing as simple as a “Hi” in the chat interface can help you kickstart the conversation with it. This makes onboarding simple for both QA engineers and non-technical team members.

There are two ways through which CoTester 2.0 learns your product context.

First, share user stories, requirement docs, or test plans in formats like PDF, Word, or CSV. CoTester uses this information to generate test cases. It’s essential to keep them rich in detail for the best possible and most accurate outcome.

Or, paste a link to a staging or production page, and CoTester scans it to generate relevant, executable test cases on prompting. This feature is beneficial for testing web forms, flows, or page-specific validation.

All uploaded files and generated assets are stored in a searchable repository, simplifying information organization and retrieval. You can add, update, or modify your knowledge base without overwriting existing data, keeping it current and reliable.

Features

• Prompt CoTester to deliver a thorough test case description and launch a step-by-step editor that demonstrates the automation workflow; add, remove, or adjust steps directly in the chat interface to customize tests
• Generate and execute tests on real browsers and devices through seamless CI/CD integration; with its AgentRx self-heal engine, CoTester 2.0 detects major UI changes, including structural shifts and full redesigns, and updates test scripts on the fly
• Produce detailed logs, screenshots, and step-by-step results after every execution; leverage CoTester’s debugging tools to pinpoint breakpoints, adapt scripts, and resolve issues faster
• Safeguard all training data within your organization’s dedicated instance; CoTester isolates deployments and protects proprietary information from being shared

Industry-specific applications

CoTester is a domain-specific expert system designed for testing websites and web applications across various industries, including BFSI, e-commerce, telecom, healthcare, and travel.

Who can use CoTester?

Business analysts, product managers, manual testers, automation test engineers, and SDETs will find CoTester helpful.

Upcoming Developments in CoTester

Mobile app testing support is in active development and will expand CoTester’s reach to cover native and hybrid mobile apps. Other planned integrations include connectivity with tools like Slack, Trello, ClickUp, Miro, Asana, GitHub, and Microsoft Teams.

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.
