note - this is a hack/workaround 🔨 @marekdedic - was stuck with same issue, couldn't find a proper solution for this, but was able to find a workaround for it based on this - jestjs/jest#1211 (comment) the linked issue, creates a file at runtime and with all require statements, instead i added a dummy spec file const glob = require('glob');
const cwd = require('path').join(process.cwd(), 'app', 'modules');
const pattern = '*.svelte';
glob
.sync(pattern, { cwd, matchBase: true, nosort: true })
.forEach((file) => require(file)); |

Can you try to change your I think you have to set this as well: Can you provide a sample repo, where the bug surfaces? |

Hi,I have previously tried both of these, but not both of them at once, which works! Switching back to babel however makes the tests error out completely :/ You can see it in action on this branch of my repo: https://github.com/skaut/shared-drive-mover/tree/svelte-jester-coverage-test |

+1 I also get the same error: Here is my jest config - import type { Config } from '@jest/types';
const config: Config.InitialOptions = {

verbose: true,
testMatch: ['<rootDir>/src/**/*.test.(js|ts)'],

'svelte-jester',
{
preprocess: true
}
],

collectCoverageFrom: ['<rootDir>/src/**/*.(svelte|ts)', '!<rootDir>/src/**/*.stories.svelte'],
coveragePathIgnorePatterns: ['\\.svg$', '/node_modules/'],
};
export default config;Once I add the untested file to a test case, the error for it disappears => @rvisharma thanks for your workaround! |

This issue remains, replicated and documented here: https://github.com/raurir/svelte-code-linting#testing |

I am also experiencing the same issue that @tobiasbueschel and @raurir mentioned, though I am not using Babel in my setup. Here is my module.exports = {
moduleFileExtensions: ['js', 'ts', 'svelte'],
transform: {
'^.+\\.svelte$': [
'svelte-jester',
{
preprocess: true
}
],
'^.+\\.ts$': 'ts-jest'
},
coverageReporters: ['json', 'lcov', 'text', 'clover', 'html'],
collectCoverageFrom: ['src/**/*.{ts,svelte}', '!src/*.d.ts']
};I get the same error message: Edit: I added |

I've bumped the jest version from when trying to include --coverage argument. I get the above error message when using However when using |
Hi,
in my configuration, I am testing svelte files written in typescript. In my
jest.config.jsonI have:{ "collectCoverage": true, "collectCoverageFrom": [ "src/**/*.svelte", "src/**/*.js", "src/**/*.ts" ], "coverageDirectory": "coverage", "coverageProvider": "babel", "projects": [ { "displayName": "frontend", "preset": "ts-jest/presets/default", "testEnvironment": "jsdom", "moduleNameMapper": { "^.+\\.scss$": "identity-obj-proxy" }, "transform": { "^.+\\.svelte$": [ "svelte-jester", { "preprocess": "__tests__/frontend/svelte.config.js" } ], "^.+\\.js$": ["babel-jest", { "configFile": "./__tests__/frontend/babel.config.js" }] } } ] }With this, coverage is not collected from untested svelte files - I do get coverage of any svelte file that has a test, however, files without any tests are not listed in the coverage report.
I am using
svelte-jester@2.1.5andjest@27.4.4- I've found similar issues here, but they should've been fixed with these versions...The text was updated successfully, but these errors were encountered:
