What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

describe('Indentation Bug', () => {

  test.each`
    a    | b
    ${1} | ${1}
  `('$a == $b', ({ a, b }) => {
    expect(a).toBe(b); // error  Expected indentation of 2 spaces but found 4  indent
  }); // error  Expected indentation of 0 spaces but found 2  indent
});

eslint .

What did you expect to happen? I would expect the code indentation to be valid.

What actually happened? Please include the actual, raw output from ESLint. Following eslint errors are displayed:

8:1  error  Expected indentation of 2 spaces but found 4  indent
9:1  error  Expected indentation of 0 spaces but found 2  indent

I’ve created a small repo where you can easily reproduce the issue. https://github.com/msvab/eslint-tagged-literal-indent-bug

Are you willing to submit a pull request to fix this bug? I can try, but I have zero knowledge on eslint internals.

It might take some time to get familiar with inner workings Eslint but I am interested in taking this up.

It’s still closed though 😉 I’d really like to get this fixed too, as I have to disable the indent rule on test-files otherwise…
