Currently, I am in the process of conducting a unit test by referring to the official guide provided. To do so, I have cloned the demonstration repository named vue-test-utils-getting-started.
To replicate the issue, follow these steps:
- After cloning vue-test-utils-getting-started, execute npm install (only required once)
- Since the file is already set up, errors may show up when running
npm test
● Validation Error:
Preset @vue/cli-plugin-unit-jest/presets/no-babel/jest-preset.js not found.
Configuration Documentation:
https://facebook.github.io/jest/docs/configuration.html
If you view the file content using the command below
cat @vue/cli-plugin-unit-jest/presets/no-babel/jest-preset.js
It will display the contents, indicating that the file exists at that location
If you comment out the line, it should work without any issues. This suggests that there might be a bug in the mechanism for loading the preset file. Do you happen to know the correct way to load the preset?
// jest.config.js
module.exports = {
// Although this is installed by default, it doesn't seem to work as intended. Many users are experiencing "not found" despite the file's existence
// preset: '@vue/cli-plugin-unit-jest/presets/no-babel'
}
