Versions

• What is this plugin's version? If this is NOT the latest released version can you try the latest version, please? 3.9.11
• If the plugin worked before in version X, but stopped after upgrading to version Y, please try the released versions between X and Y to see where the breaking change was.
• What is Cypress version?

Cypress package version: 8.7.0
Cypress binary version: 8.7.0
Electron version: 14.1.0
Bundled Node version: 14.17.0

• What is your operating system? MacOS Big Sur
• What is the shell? Bash
• What is the Node version? 16.13.0
• What is the NPM version? 8.1.0
• How do you instrument your application? Cypress does not instrument web application code, so you need to do it yourself. Yes! But I can't seem to instrument the bundled Cypress test code.
• When running tests, if you open the web application in regular browser, and open DevTools, do you see window.__coverage__ object? Can you paste a screenshot?
• Is there .nyc_output folder? Is there .nyc_output/out.json file. Is it empty? Can you paste at least part of it so we can see the keys and file paths?
• Do you have any custom NYC settings in package.json (nyc object) or in other NYC config files

// nyc.config.js
/**
 * Code coverage configuration for use with Cypress and Typescript.
 * @see {@link https://docs.cypress.io/guides/tooling/code-coverage.html}
 * @see {@link https://github.com/istanbuljs/nyc#selecting-files-for-coverage}
 */

};

• Do you run Cypress tests in a Docker container? No.

Describe the bug A clear and concise description of what the bug is.

I've been trying to follow your guide on achieving 100% code coverage by combining unit tests with E2E integration tests. But, all my application code is written in TypeScript and when I use the @cypress/code-coverage/use-babelrc package, I get the following error:

Error running @cypress/browserify-preprocessor:

You are attempting to preprocess a TypeScript file, but do not have TypeScript configured. Pass the 'typescript' option to enable TypeScript support.

Link to the repo Bugs with a reproducible example, like an open source repo showing the bug, are the most likely to be resolved.

thavmaclub/thavma illustrates this issue; the test coverage reports that lib/api/handle.ts wasn't covered entirely, but I have unit tests just for that. However, those unit tests aren't included in the test coverage because they're not instrumented because of this bug.

Example See #217 that is an excellent bug report example

@bahmutov perhaps I can compete for the issue example link? 🙃

I’m sorry but I have no time to look into this issue
