+# example: before-all-visit
+
+Code coverage example where the `cy.visit` happens in `before` hook
+
+Code was instrumented with
+
+```shell
+npx nyc instrument --compact false main.js > main-instrumented.js
+```
+
+and then removed absolute folder paths, leaving just relative path `main.js` in the produced file.
+
+The code uses custom coverage report command in [package.json](package.json) to call `nyc`
