- Eliminated `testerPath` for `TesterClass`
- Eliminated the need for the `pluginname.test.js` file if only defaults were used
    - Instead, you can now replace it with the `docpad-plugintester` executable
- Eliminated the need for the earlier premade custom tester classes (server tester, and render tester)
    - `testGenerate` now runs render tests if `outExpectedPath` exists`
    - Server tester has been removed, [following its deprecation](https://github.com/docpad/docpad/issues/1081)
