Use project's package manager directly for virtual environment management (uv by default).\n1. Specify testing dependency environments in pyproject.toml\n2. Define environments by:\n    * python versions\n    * dependency versions\n    * extras\n    * groups\n    * markers\n    * environment variables\n    * version solving strategy (e.g. lowest vs highest)\n    * tags\n2. Integrate seamlessly with github actions.\n    - Allow environments to be read into the GHA strategy matrix.\n3. Produce test matrix visualizations.\n4. Remote test matrix definitions (drive matrix from a URL holding a toml config)\n5. Dynamic Test Strategies (Experimental)\n    - Driven off endoflife.date\n    - Dynamic dependency ranges\n\n**PTM is not a test runner it is an environment definer, visualizer and bootstrapper.**\n\n*visualization idea: 2D: version x package matrix, heatmapped with shading based on number of runs version appears in, and when a version is hovered over the versions of other packages that are tested in combo are highlighted*\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbckohan%2Fptm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbckohan%2Fptm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbckohan%2Fptm/lists"}
