+### autoRevealOutput
 ```ts
 autoRevealOutput = "on-run" | "on-exec-error" | "off"
 ```
 - `on-run`: reveal test run output when test run started.
 - `on-exec-error`: reveal test run output only when execution error (note, not test error) occurred.
 - `off`: no auto reveal test output. Note this could mask critical error, check status bar status for detail.

+parserPluginOptions = { decorators?: 
+  | 'legacy' 
+  | {
+      decoratorsBeforeExport?: boolean;
+      allowCallParenthesized?: boolean;
+    }
+  }
+```
+This extension uses babel to parse the test files. For decorators [plugin options](https://babeljs.io/docs/en/babel-parser#plugins-options), it uses  `'decorators', {decoratorsBeforeExport: true}` by default, which can be customized with this setting. Examples:
+```json
+"jest.parserPluginOptions": {"decorators": "legacy"}
+
+"jest.parserPluginOptions": {"decorators": {"decoratorsBeforeExport": false}}
+```
