Hi everyone,
I am getting an error when trying to execute my unit tests using @vue/vue2-jest@^27.0.0-alpha.4 and jest@^27.1.0. As far as I know this should be solved with this PR, but upgrading from older version of jest to a new one using vue upgrade --next breaks it.
This is the error:
/path/to/file.ts: don't know how to turn this value into a node

Here's my jest.config.js:
module.exports = {
globals: {
'ts-jest': {
isolatedModules: true,
},
},
preset: '@vue/cli-plugin-unit-jest/presets/typescript-and-babel',
testEnvironment: 'jest-environment-jsdom',
testMatch: [
'<rootDir>/(src/**/*.spec.(ts|tsx|js))',
'**/tests/unit/**/*.spec.[jt]s?(x)',
'**/__tests__/*.[jt]s?(x)',
],
transformIgnorePatterns: ['<rootDir>/node_modules/(?!(lit-element)/)'],
collectCoverage: true,
coverageDirectory: 'tests/coverage',
reporters: [
'default',
[
'./node_modules/jest-html-reporter',
{
outputPath: 'tests/report/test_report.html',
},
],
],
setupFilesAfterEnv: ['./tests/unit/jest.init.ts'],
moduleFileExtensions: ['js', 'ts', 'json', 'vue'],
transform: {
'^.+\\.ts$': 'ts-jest',
'^.+\\.js$': 'babel-jest',
'^.+\\.vue$': '@vue/vue2-jest',
},
};
Am I missing something or is the bug still not solved?
Thanks a lot
