jest-junit

A Jest reporter that creates compatible junit xml files

Installation

yarn add --dev jest-junit

Usage

In your jest config add the following entry:

{
  "testResultsProcessor": "./node_modules/jest-junit"
}

Then simply run:

jest

Configuration

jest-junit offers five configurations based on environment variables or a jest-junit key defined in package.json. All configuration values should be strings.

Variable Name	Description	Default
JEST_SUITE_NAME	name attribute of <testsuites>	"jest tests"
JEST_JUNIT_OUTPUT	File path to save the output.	"./junit.xml"
JEST_JUNIT_CLASSNAME	Template string for the classname attribute of <testcase>.	"{classname} {title}"
JEST_JUNIT_TITLE	Template string for the name attribute of <testcase>.	"{classname} {title}"
JEST_JUNIT_ANCESTOR_SEPARATOR	Character(s) used to join the describe blocks.	" "
JEST_USE_PATH_FOR_SUITE_NAME	Use file path as the name attribute of <testsuite>	"false"

Example:

JEST_SUITE_NAME="Jest JUnit Unit Tests" JEST_JUNIT_OUTPUT="./artifacts/junit.xml" jest

You can also define a jest-junit key in your package.json. All are string values.

{
  ...
  "jest-junit": {
    "suiteName": "jest tests",
    "output": "./junit.xml",
    "classNameTemplate": "{classname}-{title}",
    "titleTemplate": "{classname}-{title}",
    "ancestorSeparator": " › ",
    "usePathForSuiteName": "true"
  }
}

For the following test:

describe('addition', () => {
  describe('positive numbers', () => {
    it('should add up', () => {
      expect(1 + 2).toBe(3);
    });
  });
});

The default output:

<testsuites name="jest tests">
  <testsuite name="addition" tests="1" errors="0" failures="0" skipped="0" timestamp="2017-07-13T09:42:28" time="0.161">
    <testcase classname="addition positive numbers should add up" name="addition positive numbers should add up" time="0.004">
    </testcase>
  </testsuite>
</testsuites>

Changing the classNameTemplate and titleTemplate:

JEST_JUNIT_CLASSNAME="{classname}" JEST_JUNIT_TITLE="{title}" jest

<testsuites name="jest tests">
  <testsuite name="addition" tests="1" errors="0" failures="0" skipped="0" timestamp="2017-07-13T09:45:42" time="0.154">
    <testcase classname="addition positive numbers" name="should add up" time="0.005">
    </testcase>
  </testsuite>
</testsuites>

Changing just the ancestorSeparator:

JEST_JUNIT_ANCESTOR_SEPARATOR=" › " jest

<testsuites name="jest tests">
  <testsuite name="addition" tests="1" errors="0" failures="0" skipped="0" timestamp="2017-07-13T09:47:12" time="0.162">
    <testcase classname="addition › positive numbers should add up" name="addition › positive numbers should add up" time="0.004">
    </testcase>
  </testsuite>
</testsuites>
