# MRE for `@graphql-codegen/client-preset-swc-plugin` code transformation with Jest

## To reproduce the issue

```sh

# Install dependencies

yarn

# Run the test

yarn jest issue.test.ts

```

## Actual output

Jest will produce the following output:

```

 FAIL  tests/issue.test.ts

  ● Test suite failed to run

## Expected output

Jest is expected to run and pass the test, because `1 + 1 = 2`.

While the test is a TypeScript file, there is no TypeScript-specific syntax in it, so it can be interpreted as JS too.

The imported `Foo.ts` does contain TypeScript type annotations, but otherwise uses standard ECMAScript features (classes).
