I am writing tests for my js piler and when I input a String, multiple lines are retrieved. What is retrieved is what I want to retrieve, but my test fails because I don't know how to write what is expected for jest.

This is how I call the test:

testRequireImport(
    'import { b, a } from \'@sugar/merge/*\';',
    '!EXPECTED',
    babelOptions
);

This is the reaction in the console:

    expect(received).toBe(expected)

Expected value to be (using ===):
  "import '../../top/merge/FileInTop.js';,import '../../mid/merge/FileInMid.js';,import '../../mid/merge/Second.js';,import './FileInBot.js';"
Received:
  "import '../../top/merge/FileInTop.js';
import '../../mid/merge/FileInMid.js';
import '../../mid/merge/Second.js';
import './FileInBot.js';"

Difference:

- Expected
+ Received


-import '../../top/merge/FileInTop.js';,import '../../mid/merge/FileInMid.js';,import '../../mid/merge/Second.js';,import './FileInBot.js';
+import '../../top/merge/FileInTop.js';
+import '../../mid/merge/FileInMid.js';
+import '../../mid/merge/Second.js';
+import './FileInBot.js';

Can anyone help me with writing what is expected?

• javascript
• jestjs

• You haven't said what you actually want to happen – Aron Commented Mar 17, 2017 at 15:30
• @Aron I want my test to succeed. What I receive is correct, but I want to know how to write the expected to be equal to the received. – Inbar Azulay Commented Mar 17, 2017 at 16:04

Your expected has mas where new lines should be, and your received has new lines instead of mas.

So make your expected match with line breaks

expect(received).toBe(expected.replace(',', '\n'));
