JetBrains AI Assistant test generation
By JetBrains. Category: IDE and repo test agents. Homepage
JetBrains' AI Assistant documentation describes a Generate Unit Tests action in JetBrains IDEs that writes unit tests for selected code, including methods in Ruby, PHP and C#. Generated tests are saved in an existing or newly created test module of the project. In PyCharm, the feature uses the project's default test runner. AI Assistant connects to cloud language models, and the documentation also covers local models through Ollama and LM Studio. It can act as an MCP client. Plans range from a free tier to paid tiers with AI credit quotas per 30 days.
