# Best AI platforms for generating unit tests and improving code coverage automatically?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I’ve been helping a few dev teams evaluate AI platforms that can <strong>generate unit tests automatically and improve code coverage</strong> — saving time on repetitive test writing and catching more bugs before production. I went through G2 data and reviews, and here’s what stood out:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/chatgpt/reviews"><strong>ChatGPT</strong></a> <strong>(with Code Interpreter plugins):</strong> Teams are using ChatGPT to generate unit tests in multiple languages from existing code snippets, explain test logic, and suggest edge cases to improve coverage. Especially handy when paired with IDE plugins for quick test scaffolding.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/github-copilot/reviews"><strong>GitHub Copilot</strong></a>: One of the most widely adopted in-IDE AI assistants. It can auto-suggest unit tests as you write functions and help maintain consistent test structures across projects.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/google-gemini/reviews"><strong>Gemini</strong></a><strong>: </strong>Many devs are experimenting with Gemini for auto-generating test cases and identifying missing scenarios, especially in cloud-native environments.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/replit/reviews"><strong>Replit</strong></a><strong>: </strong> Works inside Replit’s collaborative environment. It generates starter tests for functions and highlights potential untested code paths — useful for smaller teams or rapid prototyping.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/salesforce-platform/reviews"><strong>Salesforce Platform</strong></a> is More niche, but in Salesforce environments, it can generate Apex tests and improve coverage automatically for faster deployments.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true"><strong>Other popular names</strong> include <strong>Codeium</strong>, <strong>Claude Code,</strong> <strong>Tabnine</strong>, and <strong>Amazon CodeWhisperer</strong>, all known for smart code completions plus test generation features.</p>

&lt;p&gt;For those using AI to generate unit tests, which platform has given you the best boost in coverage and reliability? Do you trust the generated tests as-is or still review and tweak them manually?&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;
