# ts-jest-coverage-incorrect-line-numbers

Having an issue when running `yarn test` with `jest.config.js` `collectCoverage: true`. The line number and stack reported are incorrect.

Actual Output:

```sh

$ jest

 FAIL  src/foo.test.ts

  ✕ will it blow up? (4ms)

  ● will it blow up?

    Uh oh!

      at Object.ifCalledWillBlowUp (src/foo.ts:100:9)

      at Object. (src/foo.test.ts:4:3)

Test Suites: 1 failed, 1 total

Tests:       1 failed, 1 total

Snapshots:   0 total

Time:        1.591s

Ran all test suites.

```

Expected Output:

```sh

$ jest

 FAIL  src/foo.test.ts

  ✕ will it blow up? (4ms)

  ● will it blow up?

    Uh oh!

      1 | export function ifCalledWillBlowUp() {

    > 2 |   throw new Error('Uh oh!');

        |         ^

      3 | }
