A12 Upgrade and jest

Migration
1

Hi,
after upgrading our frontend to the newest a12 version (2025.06ext1) our jest tests have a parsing problem. What could we do to correct this?

We found a solution:

we added following snippet to out jest.config.js file:

const esModules = [
    // modules that should be transformed
].join("|");

module.exports = {
    // ...other configs
    transformIgnorePatterns: [`/node_modules/(?!${esModules}).+\\.js$`],
    transform: {
        "^.+\\.[tj]sx?$": "ts-jest"
    }
}
